Polycom is pleased to announce the release of Polycom PVX™ version 8.0.2.
Polycom PVX version 8.0.2 delivers unprecedented technology and
performance to computer video conferencing. With premium audio and video
algorithms and enhanced collaboration features, the Polycom PVX software
delivers power and performance never before seen in computer video
conferencing.
Working together with a computer and a standard USB camera, the Polycom
PVX 8.0.2 software application brings video conferencing to your desktop. It
is ideal for employees who work from home, sales or consulting professionals
who travel, educators conducting distance learning events, or health care
professionals delivering services in remote facilities. Polycom PVX software
extends Polycom’s unmatched capabilities and conference room performance
to the desktop.
Polycom PVX 8.0.2 will continue to support the ViaVideo™ and ViaVideo II
cameras. However, Polycom recommends using standard USB 2.x webcams to
achieve the highest video quality. When you choose a standard webcam, the
computer’s processing capabilities let you use additional features such as
H.264 and Siren™ 14. View-only mode allows users without cameras to
participate in video conferences using audio and to share content using
People+Content™ and standards-based H.239.
What’s New in Release 8.0.2?
Polycom PVX 8.0.2 is a maintenance release. This release includes general
improvements to SIP interoperability and stability, support for the SIP Express
Router (SER) SIP server, and other minor improvements.
What’s New in Release 8.0.1?
Polycom PVX 8.0.1 is a maintenance release. A number of minor
improvements have been added to PVX for this release; however, the major
change is that you can now specify the CPU resources required by your
camera.
A new tab, the Advanced Tab, has been added to the Video page. Settings on
this tab allow you to configure PVX to compensate for a higher CPU load from
your camera driver. You can lower the estimated CPU power by a fixed
amount and, thereby, enhance the quality of your PVX video.

Supported Audio Devices and Webcams
Polycom PVX software is tested extensively with a wide range of audio devices
and webcams. For a list of compatible devices and for important information
about factors you should consider when selecting your audio and video devices,
refer to the Selecting Audio and Video Devices for Use with Polycom PVX document,
available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.
SoundStation2 and SoundStation2W
To make calls with PVX using the Polycom SoundStation2™ or
SoundStation2W™, you need the Computer Calling Kit. For more information
about this kit, refer to the Selecting Audio and Video Devices for Use with Polycom
PVX document, available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.
System Performance
For systems with a ViaVideo or ViaVideo II camera, most of the media
processing is done by the camera. People+Content sharing requires computer
processing and, therefore, demands a higher performance processor. Systems
with a 1.2 GHz Pentium 4 or later can support People+Content. Content sharing
will benefit from additional CPU speed.
For systems with a webcam, all of the processing is done on the computer. There
are a wide range of computer performance levels. To optimize the video
experience on each system, a CPU resource manager within the Polycom PVX
software gauges the system performance and adjusts the media features
accordingly.

Polycom PVX
Great audio and video while reducing the responsiveness of
other applications.
Factors Affecting Video
The video format in a call depends on many factors — both on the near-site
system and on the far-site system.
Some of the other factors that can affect the video format include:
•
System processor and speed
•
PVX settings under Setup > General > Performance
•
PVX settings under Setup > Video
•
Gatekeeper configuration under Setup > H.323
•
Audio format
•
Presence of content video (send or receive)
•
Camera type
Camera Driver Load
The For the camera you have selected, specify the camera driver’s load on the
system setting on the Setup > Video > Advanced page allows you to configure
PVX properly, especially if you need to compensate for a higher CPU load
from the camera driver. This setting enables you to lower the estimated CPU
power by a fixed amount so you can enhance the quality of your PVX video.
The original video capture driver load for PVX is approximately 150 MHz
worth of CPU resources. Therefore, on a 1.5 GHz computer, the video capture
driver will use 10% of the CPU (you can check this using the Task Manager).
On a faster computer, the load will be less, such as 5% on a 3.0 GHz system.

PVX 8.0.2 Processor/Bit-rate/Resolution Tables
The tables in this section provide overall targets for different computer processor
types and call speeds.
Keep the following in mind when viewing the tables:
•
The values listed in the tables assume that PVX is set to Balanced on the
Setup > General > Performance page. If you select Other Applications on
this page, PVX will use less processing power; if you select Polycom PVX,
PVX will use more of the CPU. For more information, refer to System
Performance on page 5.
•
The values listed are based on the Low camera driver load setting. To check
this setting, see the For the camera you have selected, specify the camera
driver’s load on the system field on the Setup > Video > Advanced page. If
your camera driver load setting is set to High or Medium, you must
manually compensate for the different setting as follows:
— If your camera driver load setting is set to High, subtract 600 MHz from
the speed shown. For example, if your system’s CPU speed is 2000 MHz,
subtract 600 MHz from that, for a total of 1400 MHz.
— If your camera driver load setting is set to Medium, subtract 200 MHz
from the speed shown. For example, if your system’s CPU speed is 2000
MHz, subtract 200 MHz from that, for a total of 1800 MHz.

Release Notes
Polycom PVX Version 8.0.2
Updating to PVX Version 8.0.2
To install Polycom PVX 8.0.2 for the first time or to upgrade from Polycom PVX
6.x or 8.x:
1. Close any programs running on your computer.
2. If you are using a ViaVideo or ViaVideo II camera, make sure that the
camera is turned off.
3. Download the PVX version 8.0.2 installation file from the Polycom
website, www.polycom.com/videosoftware.
4. Double-click the downloaded installation file.
5. When the install wizard starts, follow the instructions on the screen.
6. When installation is complete, verify the new software version number in
the Polycom PVX System Information screen.
Post-Installation Note:
Should you decide at any time to reinstall PVX version 6.x, you must first uninstall version
8.0.x using the Microsoft Windows Add/Remove Programs utility. Before uninstalling PVX,
make a note of your existing user settings and directories and back up any files that you
personally created and placed in the PVX program files directory, typically C:\Program
Files\Polycom\PVX, that you wish to save. All files in the PVX directory are deleted during the
uninstall process.
Tools for System Administrators
The tools listed in this document are being made available to system
administrators to facilitate deployment and management of PVX systems. The
PVXSET utility allows administrators to set or query PVX configuration
properties. The PVX Capability Viewer allows administrators to view the
video capabilities for a variety of system configurations.
While these tools are now being offered by Polycom, their immediate use is
contingent upon their implementation “as-is” and without technical support
from Polycom Services. Fully supported versions of these tools may be made
available in a future release of the Polycom PVX software.
As always, user feedback is encouraged. Your comments and suggestions will
assist in the future planning and development of these and other tools for
system administrators that will ultimately enhance the Polycom PVX user
experience. To submit feature enhancement ideas, go to www.polycom.com
and click on Support > Video > Suggest Product Enhancements.

Release Notes
Polycom PVX Version 8.0.2
PVXSET Utility
Note: Polycom does not support the PVXSET utility.
PVXSET is an unsupported utility that enables administrators to set or query
PVX configuration properties. The PVXSET application and a sample .pvp file
(sample.pvp) are installed automatically when you install the PVX software.
The sample file contains additional information about using PVXSET.
When PVX is installed, the .pvp and .pvq file extensions are associated with
the PVXSET utility. Double clicking a file with one of these extensions will
cause PVXSET to process that file.
You can run PVXSET while the PVX application is open or closed. Please note
that if PVX is open when you set properties, some property changes may not
take effect until PVX is closed and restarted.
When you start PVXSET, you see a status dialog showing the name of the file
that is running and the completion status. Click Details to display each
property that was processed in a .pvp file.
Keep the following guidelines in mind when you create your .pvp and .pvq
files:
•
List each property on a separate line.
•
Blank lines are ignored.
•
Use only valid property names. See sample.pvp for a list of recognized
property names.
•
Start comment lines with a semicolon. Comments cannot be on the same
line as a property.
Using PVXSET to Set Properties
To set properties, you create an ASCII text file with a .pvp extension. This file
contains the properties and values you want to set. See the information
contained in the sample.pvp file for a list of recognized properties and the
allowable settings for each.
Use this format for each property. Note that if you leave the value blank, the
property is set to an empty value.
property_name = value
The following example sets the AES Encryption property to Auto:
; AES encryption: 0 - None, 1 - Auto
H323_ENCRYPTION = 1
Using PVXSET to Query Properties
To get properties, you create an ASCII text file with a .pvq extension. This file
contains the properties you want to query. See the information contained in
the sample.pvp file for a list of recognized properties and the allowable
settings for each.
13
Release Notes
Polycom PVX Version 8.0.2
When you run the query, the results are saved to a .pvp file in the same
directory and with the same root name as the source .pvq file. For example,
running C:\pvxsetfiles\gatekeeper.pvq generates a new text file named
C:\pvxsetfiles\gatekeeper.pvp.
Use this format for each property you want to query.
property_name =
The following example queries the system to discover the AES Encryption
setting.
; AES encryption: 0 - None, 1 - Auto
H323_ENCRYPTION =
Using .pvp Files to Initialize Systems for New Users
Most PVX properties are unique to each PVX user; however, some properties
are computer-specific (that is, they are common for all users on a particular
computer). When a new user launches PVX for the first time, PVX will
initialize properties for that user. If that user is the first user on the computer,
PVX will initialize the computer-specific properties, as well.
At first launch, PVX displays a setup wizard to help the user to set up the
system. Alternatively, an administrator could provide a .pvp initialization file
that contains the initial settings. This file could contain all or some of the
needed values. The file must be named InitConfig.pvp, and it must reside in
the same folder as the PVX executable, ViaVideoNG.exe (typically
C:\Program Files\Polycom\PVX). Refer to the sample.pvp file for more
information about creating an InitConfig.pvp file.
The first time each user on the computer opens PVX, PVX parses the
configuration file, sets the designated properties, and then proceeds with the
first-time-use initialization.
Running PVXSET from the Command Line
PVXSET supports three quiet modes when you run the application from the
command line.
14
•
Normal mode displays all messages. For example, this command runs
sample.pvp in normal mode:
pvxset sample.pvp
•
Super quiet mode suppresses all messages, progress messages, warning
message, and error messages. To run in super quiet mode, precede the file
name with /qq. For example, this command runs sample.pvp in super
quiet mode:
pvxset /qq sample.pvp
•
Quiet mode suppresses all messages except error messages. To run in
quiet mode, precede the file name with /q. For example, this command
runs sample.pvp in quiet mode:
pvxset /q sample.pvp

Release Notes
Polycom PVX Version 8.0.2
PVXSET Feature Limitations
•
When you use PVXSET to set the license number and key code running the
system for the first time, PVX crashes on startup. When you use PVXSET
to set the license number and key code running the system for the first
time, the software is not activated. To activate the license, run the setup
wizard, and then use PVXSET to set the license number and key code.
When you use PVXSET to set the license number and key code, calls are
limited to 5 minutes until PVX is restarted. PVXSET cannot be used to
query password values. If you attempt to query password values using a
.pvq file, the resulting .pvp password value will contain “<password
value is hidden.>” If you run this .pvp file, the password will be changed.
•

PVX Capability Viewer
The PVX Capability Viewer allows administrators to view the video capabilities
of various system configurations. This program can be found in the PVX
program files directory, typically C:\Program Files\Polycom\PVX.
To view the capabilities of a system:
1. Double-click the VvCapView.exe application file.
2. Do one of the following:
— To view the capabilities of the current system, clear Choose a different
PC configuration.
— To view the capabilities of other system configurations, click on the
Choose a different PC configuration check box, select a computer
model, and enter both the processor speed and size of the L2 cache.
3. Click View to view the Summary window, which displays system
capabilities in Balanced mode.
4. In the Summary window, click Details to view the system capabilities for
all three performance modes: Balanced, Favor Other Applications, and
Favor Polycom PVX.
5. In the Details window, click Save to save the capabilities detail to a text file.
The capabilities shown in the VvCapView.exe file are based on the Low camera
driver load setting. To check this setting, see the For the camera you have
selected, specify the camera driver’s load on the system field on the Setup >
Video > Advanced page. If your camera driver load setting is set to High or
Medium, the VvCapView.exe file does not reflect this, so you must manually
compensate for the different setting as follows:
•
If your camera driver load setting is set to High, subtract 600 MHz from the
speed shown in the Speed field in the VvCapView.exe file. For example, if
the Speed field shows 2000 MHz, subtract 600 MHz from that, for a total of
1400 MHz.
•
If your camera driver load setting is set to Medium, subtract 200 MHz from
the speed shown in the Speed field in the VvCapView.exe file. For example,
if the Speed field shows 2000 MHz, subtract 200 MHz from that, for a total
of 1800 MHz.
For more information about the camera driver load, refer to the Selecting Audio
and Video Devices for Use with Polycom PVX document, available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.

Release Notes
Polycom PVX Version 8.0.2
Several profiles can be created for a single user. Then, whenever the system is
moved to a different location, the profile selection can simply be changed
rather than having to change multiple network settings on various Setup
pages.
Location profiles are configured from the Setup > Network page. PVX
provides three default profiles: Office, Home, and Travel.
•
To activate a profile, simply choose the location name from the list.
•
To create a new profile, change a profile name or description, or copy, edit,
or delete a profile, simply click the Configure Profiles button.
All the configuration settings on the Network page apply to a location profile,
including all items on the Connection, Ports, QoS, and Bandwidth pages.
Other settings that are defined per location are:
•
General > Call Settings Page
— Maximum time in call
•
Video > Video Sources Page (for ViaVideo cameras only)
— Power Frequency
— 60 Hz
— 50 Hz
•
H.323 Page
— Use PathNavigator™ OneDial for gateway calling
— Dial Prefix

•
You may notice an increase or decrease of the system’s audio volume level
when starting the Polycom PVX application.
•
When using a headset with the ViaVideo or ViaVideo II cameras, connect
the headset to the camera via a 2.5 mm stereo jack to the 3.5 mm stereo
plug adaptor. While many cell phone headsets are compatible for use with
ViaVideo cameras, those that support an audio range up to 7 kHz are
recommended.
•
While PVX supports audio algorithms up to Siren 14, audio algorithms up
to G.722 only are supported in calls using a ViaVideo or ViaVideo II
camera. This is a limitation of the camera.
•
If a ViaVideo or ViaVideo II camera's audio cable is connected to a
microphone jack and the playback volume is too loud, check to make sure
that there is no microphone level adjustment enabled. This may be labeled
Microphone Boost on some audio devices.
Calling Issues
20
•
Before troubleshooting calling issues, check first to ensure that the latest
firmware versions and device drivers are downloaded onto all peripherals
such as routers, webcams, etc., that are connected to the PVX system.
Often, simply updating these items with the latest drivers or firmware will
correct the problem.
•
If you switch to a different camera while recording VideoMail, the system
begins recording a new VideoMail instead of continuing to record the
existing VideoMail.
•
System names that contain the ampersand character (&) may not be
displayed correctly on the System Information page. In addition, system
names that contain the ampersand character (&) cannot be added to the
Global Management System™ using the Global Management System web
interface.
•
In a call between two PVX systems, if you enable VGA People and then
disable it, the transmit people frame rate drops to 15 fps. The frame rate
returns to 30 fps after you restart PVX.
•
On a PVX set to use the “Other Applications” performance setting,
sending content in an H.323 768 kbps call uses 85% of the system
resources.
•
In a 64 kbps call between PVX and Windows Messenger, the receive
bandwidth on the PVX is much higher than 64 kbps. This is a known
characteristic of Windows Messenger.
•
After you restart a Japanese system, you must click the Change Password
button twice on the Setup > Locks page the first time you try to open the
Change Password dialog box.
•
In a 768 kbps video switching conference with H.263 video, a PVX system
using a webcam may connect in secondary mode (audio only).
•
Although PVX supports both encrypted call mode and H.239, some

3725-22754-006/A
Release Notes
Polycom PVX Version 8.0.2
encounter difficulty with call connection or data sharing and your system
is connected to a NAT/firewall, you may experience better results by
disabling one or both of these options in the Polycom PVX application.
•
When you are in an audio-only call, you may lose your local video if you
click the PIP button. Local video will return once the call is terminated. To
avoid losing local video, do not click the PIP button in an audio-only call.
•
If your system is registered with a gatekeeper, you must use quotes when
you call an alias or extension that includes a space in the name. For
example, to dial Polycom Austin as an alias, you must enter “Polycom
Austin” in the address field to connect the call.
•
When placing a call from the Directory dialog either by manually entering
an address or by selecting a number from a directory, use the Call Quality
list to choose a call rate for that address. The selected rate will override the
rate stored in the directory for that number. If you choose a different
address from the directory, the call will be placed using the rate stored in
the directory rather than the Call Quality override rate.
•
If you change the available speeds on the directory list or remove the
current directory default speed, you must go back to the directory and
explicitly change to the new speed. If you do not select a new speed in the
directory, Polycom PVX will continue to place calls at the previous default
speed, even though that speed no longer appears in the list. Go to the
Network > Bandwidth page and click on the Call Speeds button to select
up to six speed settings.
•
If you are having problems with E.164 or ISDN dialing, check that the Dial
using H.323 extension when connected to a gatekeeper setting is enabled
on the Setup > Directory page.
•
You may see incorrect information in the Recent Calls list when dialing
E.164 prefixes through an MCU.
•
Encryption is not supported when the system is registered to a gatekeeper
that is configured to do H.245 routed signaling. Either change the AES
Encryption setting to Off on the Setup > General > Call Settings page or
disable H.245 routed signaling on the gatekeeper.
•
The use of the Call Forwarding feature requires that your system be
registered with a gatekeeper. Once you have registered your system with
a gatekeeper, the Call Forwarding options will be enabled.
•
The use of People+Content requires calling speeds above 128 kbps.
•
When dialing into a password-protected VSX™ multipoint call from PVX,
you may encounter black video for up to 30 seconds. During this time, the
far-site system is being prompted to accept or decline your incoming call.
PVX endpoints will not be prompted to enter a password.
•
Once you have closed a PVX chat session, you must reactivate data
sharing by turning it off and then on again before beginning a new chat
session.
•
The Maximum Call Rate setting on the Bandwidth tab under Setup >
Network does not currently apply to inbound SIP calls.
•
Dynamic bandwidth allocation is not currently supported in SIP calls.

•
PVX calls that are transferred to an invalid extension will display black
video and require manual disconnection of the call.
•
When a call is placed from a PVX system registered to a gatekeeper to an
endpoint with call forwarding activated, the entry saved to the address
book when the call completes will need to be modified. The IP address of
the endpoint will appear correctly in the address book, but the system
name will not.
•
In a call using Toolbar View, when you click the Transfer button on the
Toolbar, the call is transferred to the address in the Enter address and
click Call to dial field.
Microsoft Windows Issues
•
If you experience difficulty with PVX call connection, ensure that the latest
Microsoft Windows updates are installed on the operating system. Often,
simply installing the latest updates will correct the problem.
•
Do not change the screen resolution when PVX is running. If you need to
change the screen resolution, exit from the PVX application, change the
resolution, and then restart PVX.
•
Changing the Windows font size while PVX is running causes PVX to
crash.
•
On a Windows 2000 system, VideoMail recorded when PVX is muted does
not include audio. On Windows XP systems, VideoMail includes audio
regardless of whether the system is muted.
•
On a Windows 2000 computer, if you turn off or disconnect a ViaVideo
camera while PVX is running and then restart the system, PVX may fail to
properly initialize. To correct this problem, reconnect or turn on the
ViaVideo camera, and restart PVX. To prevent this problem, go to Setup >
General page and choose Always Use ViaVideo hardware.
•
When you install the ViaVideo camera and Polycom PVX software on a
Windows 2000 system, you must restart the computer in order to complete
the installation. If you do not restart the computer, DiffServ does not
display correctly.
•

Some laptops will slow the clock speed when running on batteries,
thereby causing the Polycom PVX software to show a processor alert. To
correct, connect the computer to AC power and restart Windows or
reconfigure the Power Options settings in the Windows control panel to
maximize performance (shorter battery time).
NAT/Firewall Traversal
•
PVX does not save the Use UPnP router to detect address setting correctly
as part of a Profile. To work around this problem, manually re-enable this
setting when you switch to a Profile that should use UPnP.
•
When the PVX system is configured to be behind a NAT/firewall and set
to use a UPnP router to detect the address, the IP address is not always
displayed on the home screen.
Network Issues
•
The QoS tab on the Setup > Network page has been simplified so that a
single setting allows you to enable or disable QoS. In PVX version 8.0.0, IP
Precedence and DiffServ had to be set separately, which did not work
reliably on all Windows systems.
•
Restoring the system to factory defaults does not reset the allocation of
system resources to the “Balanced” setting. The default port on a server is
typically 1002 or 389, depending on the installed versions of ILS and
Windows. Note that the default port for PVX is 389.
•
If you change the Media port range on the Ports tab of the Setup >
Network page and then upgrade to PVX version 8.0.2, the values you
entered in the Media port range field will be set back to the default values.
•
If you register to an invalid Global Directory Server, the PVX user interface
may hang briefly and then recover.
•
Users with the Windows XP operating system will not be able to place or
receive video calls if the Internet Connection Firewall is enabled. To
correct this:
1. Right-click My Network Connections.
2. Select Network Properties.
3. In Local Area Connection Properties, select Advanced.
4. Clear the Internet Connection Firewall option.
•
Users running Windows XP Service Pack 2 may experience difficulty
establishing a connection to incoming calls through a firewall. If this
occurs, do the following:
1. Click Start and then choose Settings > Control Panel.
2. Select Windows Firewall.
3. Select Exceptions.

4. Confirm that the vvsys.exe and Windows NetMeeting check boxes
are selected.
•
T.120 may not work properly through some NAT devices.
•
If calls stop working after you configure the software and the NAT device,
ensure that the NAT is still configured properly. Internal testing has
shown that some NAT devices can lose their settings and must be
reconfigured. Verify that you have the latest firmware for your NAT
device.
•
After installing a new NAT device and configuring the NAT device
settings in the Polycom PVX software, you must power cycle both the
device and the computer. To do this:
1. Close all applications currently running on the system.
2. Power off the computer.
3. Power off the NAT device.
4. After 30 seconds, power on the NAT device.
5. Power on the computer.
6. Restart Polycom PVX.
•
If the system is registered with an Internet Locator Server or a Global
Directory and you delete the server address, the system displays a server
error message. Clear the Register check box instead.
•
Auto-discovery of a gatekeeper may not operate properly if the PVX
system is connected to a router.
•
PVX calls conducted over a network that uses a combination of both a
NETGEAR® router and a Cisco® Gatekeeper may disconnect after a
period of approximately four minutes.
•
PVX systems registered to the Global Management System that are also
located behind a NAT must open port 3603 (TCP) on the NAT firewall
device.
Session Initiation Protocol (SIP) Issues
24
•
T.120 is not supported in SIP calls.In a SIP call that uses a 128 kbps
continuous presence meeting room on the MGC™, the audio is received
before the video. In a SIP call from a system behind a UPnP router, the
receiving site sees the calling system's internal IP address instead of the
external address. In a SIP 768 kbps transcoding MGC call with auto audio
and H.263 video, the IP+48 card on the MGC crashes when the second
PVX starts to connect. If you place a SIP call using a SER server and hang
up before the call connects, your PVX system crashes. You can specify the
server name in the format <host>:<port>, where <host> can be either an
IP address or a DNS name.
•
Encryption and People+Content do not work in SIP calls.
•
On the Setup > SIP page, you must enter the IP address of the SIP proxy
server in the Proxy Server field. In PVX version 8.0.0, you were not
3725-22754-006/A
Release Notes
Polycom PVX Version 8.0.2
required to enter the Proxy Server if it was the same as the Registrar
Server; however, in version 8.0.2 you are required to enter an address in
both fields in order to register to the server.
•
If you register to a SIP server on the Setup > SIP page, unregister, and then
place a SIP call, the far site will display your IP address as unreadable
characters. To correct this issue, restart the system after changing SIP
server settings.
•
SIP calls to systems using MSN Windows Messenger or Microsoft Office
Communicator may:
— Report incorrect calling rates on the PVX Media Statistics page.
— Connect with audio only.
— Connect at line rates lower than those requested when the call was
dialed.
— Fail to resume video transmission if the Pause feature on
Communicator is activated.
•
PVX SIP calls to a VSX version 7.5.2 may intermittently fail to connect.
Redialing the call or upgrading the VSX to version 8.x will correct the
problem.
•
If two PVX endpoints with identical user names both register to the same
Microsoft LCS server, the second user to register will be able to answer
incoming PVX SIP calls from a third system. The first to register will not.
•
PVX systems located behind a Cisco PIX® firewall will be unable to
receive incoming SIP calls routed through a Microsoft LCS server.
•
Nortel MCS Servers will confirm registration of a PVX system even if a
blank or incorrect server password is used.
•
Nortel MCS servers do not support PVX SIP calls that use a ViaVideo
camera.
•
PVX SIP calls through an SMC SMC7004BR NAT firewall device will
transmit an incorrect IP address to a far-site system. If the far-site system
saves that information in the address book and attempts to place a return
call using the saved entry, the call will not connect.
•
If a PVX system that is registered to a Microsoft LCS server does not
answer an incoming SIP call, the call cannot be returned using the address
as listed in the Recent Call log.
User Interface
•
In this version of PVX, you must enter the access password on both the
Page Access page and the Feature Access page.
•
To display help on using the menu tree in the PVX Setup screens, click the
? Button in the upper left corner of the screen and then click the menu tree.
Displaying help by right-clicking the menu tree is not supported.
•
The help topic which describes the setup pages incorrectly implies that the
user can set the default SIP port.

Polycom PVX Version 8.0.2
•
The online help incorrectly states that you can enter the password on
either the Page Access or the Feature Access pages. In the current version,
you must enter the password on each page in order to change any settings.
•
The online help incorrectly states that you can set the default SIP port. The
default SIP port cannot be changed by the user.
•
On some wide-screen laptops, the PVX screen title text may be distorted.
ViaVideo and ViaVideo II Hardware Issues
•
Do not shut down PVX while the ViaVideo or ViaVideo II camera is being
loaded. Doing so causes vvsys.exe to crash.
•
The Polycom PVX software may intermittently fail to recognize the
ViaVideo cameras. If this happens, close the camera's shutter for
approximately 10 seconds and reopen it. You may need to restart the
Polycom PVX application if the camera preference is set to Use ViaVideo
hardware if present.
•
ViaVideo camera users who do not plan on switching between their
ViaVideo and a webcam, should configure their system to always use
ViaVideo hardware. This prevents Polycom PVX from switching to
webcam mode if a ViaVideo camera is not detected on startup. To do this,
go to the Setup > General page.
•
If you use a laptop docking station, you may encounter difficulty while
loading the ViaVideo camera's firmware. If this happens, connect the
ViaVideo unit directly to computer's USB port.
•
If you experience problems loading ViaVideo firmware through a USB
hub, connect the ViaVideo unit directly to computer's USB port instead.
Video Issues
26
•
If you are using a new Logitech QuickCam for Notebooks Pro camera, you
may see horizontal streaks in the video under very low lighting
conditions.
•
With some webcam drivers, the camera appears to be connected when it
is not actually connected. The system does not display an alert and no
video is displayed locally or during a call.
•
Users may experience no video from the Polycom PVX application after a
computer restart or upon leaving hibernation or standby mode. To correct
this, cycle the power switch to refresh the ViaVideo camera's firmware.
•
Users may experience no video from the Polycom PVX application after a
computer restart if Auto-Start Application in Background under the
General tab is selected. To correct this, open the system's Windows Task
Manager, click on the Processes tab, click on vvsys.exe, and click End
Task. Exit the Windows Task Manager and restart the Polycom PVX
application.
•
For optimal low light calibration with the ViaVideo camera, the camera
lens must be completely covered. To cover the lens, move the slider on the

6. When prompted, move the slider on the front of the camera to the
middle position to cover the lens.
•
ViaVideo cameras may display corrupted video if the camera has been on
for a long period of time. Use one of the following solutions to correct:
— Recycle the power on the ViaVideo camera.
— Close all programs and restart the Polycom PVX application.
•
When the user launches the Polycom PVX application, the application
loads software to the ViaVideo camera. This is normal operation for the
ViaVideo unit. This occurs when:
— The camera is powered on.
— The computer is restarted and the application is launched while the
camera is powered on.
•
The ViaVideo camera software may fail to load when the customer is
using a non-powered USB hub. Complete the following steps to load the
software to the camera:
1. Power off the ViaVideo camera.
2. Disconnect the USB cable from the back of the ViaVideo camera.
3. Verify that the Polycom ViaVideo device driver has been removed
from the computer's device manager.
4. Reconnect the USB cable to the back of the ViaVideo camera.
5. Power on the ViaVideo camera.
6. Verify the existence of the Polycom ViaVideo device driver in the
computer’s device manager.
Note: If the Polycom ViaVideo device driver is not present, restart the
computer and repeat steps 1-5.
7. Launch the Polycom PVX application software.
•
To optimize video quality, application sharing is disabled in Polycom PVX

Upgrading the 6.0.1 system to PVX version 6.0.2 will correct the problem.
VideoMail Issues
•
If you are having difficulty saving a VideoMail file, it may be because
Windows has not appended the .asf extension correctly in the File Save
dialog box. If you explicitly enter the .asf extension as part of the file name,
the file will be saved correctly. For example, in the file name field, enter the
file name as MyVideoMail.asf.
•
Recording VideoMail is interrupted when an incoming call is
automatically answered. To resolve this issue, turn off the Auto-Answer
feature.
•
If you leave the VideoMail box open after recording a VideoMail message
and then place a call, you cannot play or record VideoMail until you close
the VideoMail box and then reopen it.
•
The VideoMail feature cannot be used if you are in a call and the
VideoMail control panel is disabled.
•
Use of the VideoMail recording feature with third party cameras is
currently supported on Windows XP operating systems only.
•
If you expand the PVX window to preview a VideoMail recording and the
video image does not expand as well, the problem may be resolved by
temporarily disabling hardware acceleration. To disable hardware
acceleration, go to the Setup > Video page and clear the Use DirectX
Hardware Acceleration box.
•
Because VideoMail is recorded to the system’s hard drive, the size of a
VideoMail recording is limited only by the available space on your hard
drive.

system field, and then you press Reset to restore the system defaults, the
camera driver load setting does not change back to Medium. Since this
setting is machine-dependent, it does not get automatically restored.
If you have a new Logitech camera, such as the QuickCam 5000 Pro, Orbit MP,
QuickCam Fusion, or a new QuickCam for Notebooks Pro, the local video may
become choppy or may freeze if you enable Enable VGA 30 frames per second
on the Setup > Video > Advanced page. For most cameras, you should not enable
this setting. For important information about how to set this and other settings
to achieve optimum video quality, refer to the Selecting Audio and Video Devices
for Use with Polycom PVX document, available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.
Polycom has qualified the cameras listed in the Selecting Audio and Video Devices
for Use with Polycom PVX document (available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf)
for use with Polycom PVX software. Many other cameras with Microsoft WDM
video capture support will also work, although some are not fully compatible or
place their own demands on the CPU that prevent them from being included on
the list. Polycom continues to evaluate cameras and will add them as
appropriate.
•
Very high CPU usage can be seen in a number of situations:
— On systems with less than a 2.0 GHz Pentium 4 or equivalent, the
software is very busy with media processing with only a modest amount
left for other applications. Changing the resource allocation under the
Setup > General > Performance page to favor Other Applications can
reduce the load for video processing.
— On systems with some video capture devices, including some USB 2.0
cameras, the camera driver can use a high percentage of the CPU to do
video capture. If you see the CPU load above 40% while previewing
local video when not in a call, this can be the cause. Changing the system
resource allocation to favor Other Applications under the Setup >
General > Performance page can help with this somewhat. Please verify
that you have the latest video capture drivers for your device.
— When sending the desktop to the far site, you should see the CPU at or
above 95%. This is expected since the desktop capture and encoder are
busy running to provide the best desktop video quality. This code is
running at a lower priority than normal applications, which ensures that
those applications run first, but that desktop video uses all remaining
CPU resources.
For important information about how to manage CPU resources to achieve
optimum video quality, refer to the Selecting Audio and Video Devices for Use with
Polycom PVX document, available at
http://www.polycom.com/common/pw_item_show_doc/1,1276,4556,00.pdf.
•
If you experience no video or audio in a call, please verify that the latest
hardware drivers are installed and check the video or audio with the
vendor's software to verify that the operating system can handle the device
properly. This can make a significant difference in media performance.

•
In some cases the graphics interface in older systems is too slow to render
video properly. This is especially true when multiple video windows are
open at the same time or if a video window is stretched to a larger size.
This can be an issue with older video cards.
•
You can connect multiple third-party cameras; however, not all types of
cameras work with other cameras. If you experience problems using a
system with two third-party cameras connected, try connecting only the
camera you want to use.
•
Multiple cameras of the same model are not supported.
•
The camera configuration dialogs are provided by the camera vendor and
may not be translated into all languages.
•
If you wish to designate a preferred camera on the Setup > Video page,
you must connect the camera prior to starting the PVX application.
Otherwise, the camera will not appear as a selection in the Preferred
Camera list.

Interoperability and Compatibility Issues
Product
Issue
Aethra Vega Star Gold
In calls with Aethra Vega Star Gold version 5.2.11 systems
using H.239, content can be sent by PVX to the Aethra
system, but not received.
Check Point Firewall
PVX H.323 calls through a Check Point Firewall version NG
R55 may connect without audio or video.
Cisco VPN
This version of Polycom PVX interoperates with Cisco VPN
software version 4.0.3F and later.
Cisco PIX Firewall
The Cisco PIX firewall version 6.3 (4) does not support PVX
H.323 dual stream calls with H.323 aware enabled. To correct
this, disable the H.323 aware feature on the Cisco PIX
firewall.
Cisco IP Gateway
The Cisco IP Gateway does not currently support PVX calls
using People+Content, H.239 data sharing or encryption.
Creative Webcam Live! Pro
camera
On some systems using the Creative Webcam Live! Pro
camera, there may be periods when the display of local video
may have a very slow frame rate (video appears jerky). This
behavior may occur at the beginning of a call, while recording
video mail, or immediately after starting PVX, and it may last
5-30 seconds. During this period, video transmitted to the far
site will be seen at a normal frame rate. Any recorded video
mail will also play back at a normal frame rate.
Ezenia! MCU
When using the Polycom PVX software with an Ezenia! MCU
version 6.0, AES encryption must be disabled.
Fusion camera
Video sent from a PVX system using a Fusion camera
periodically displays bright white video artifacts in calls
experiencing packet loss.
Microsoft NetMeeting
The Polycom PVX application does not support G.723 audio
when using a webcam. This means that connections to
endpoints like NetMeeting that previously connected at G.723
may now connect with G.711. The call rate must be increased
to 128 kbps or above or there will be no video.
NetMeeting calls to a PVX system that are subsequently
transferred by PVX will disconnect. NetMeeting does not
support Call Transfer.
NETGEAR UPnP Router
A NETGEAR UPnP router may stop forwarding audio and
video to the PVX system after a call has been connected for
several minutes. A PVX configured to use a NETGEAR NAT
receives black video when the far end sends content. If
possible, configure both the NAT device and the PVX to use
UPnP. A PVX behind a NETGEAR NAT cannot register to a
gatekeeper if the port settings are set manually. If possible,
configure both the NAT device and the PVX to use UPnP.

Release Notes
Polycom PVX Version 8.0.2
Product
Issue
Polycom Global
Management System
Global Management System managers may notice incorrect
caller ID listed under the Call Status tab in the Global
Management System Manager. This occurs when a Polycom
PVX is in a video call with a ViewStation FX.
The current version of Global Management System does not
display alert messages from PVX systems.
Polycom iPower
T.120 does not work with an iPower if the iPower is configured
for encryption required.
iPower systems do not accept transferred calls from Polycom
PVX at this time.
When sharing data from PVX to an iPower system, you must
wait until the readiness tone is heard before sending data.
Sending data before the receiving end is ready to accept it,
may result in having to disconnect and redial the call.
During audio-only calls to an iPower system, the data-sharing
buttons on the PVX system may appear to be active and
functional when they are not.
Polycom MGC
Polycom PVX does not support sending snapshots when in a
conference call with an MGC-100 using H.261 protocols. To
correct this, reestablish the call using H.263 protocols.
Users may experience ghosting and freezing image video
when in a video call with an MGC-100 bridge running software
version 5.0. MGC version 5.1 addresses this issue.
PVX far end camera control (FECC) is not operable on SIP
calls through a Polycom MGC conferencing bridge.
When deactivating a T.120 data-share through a bridged MGC
call, the data-share option buttons may continue to appear
active and functional in the PVX application when they are
not.
PVX SIP calls through an MGC bridge to a VSX system
running version 7.5.2 may result in no audio being heard from
the VSX system.
In a 384 kbps transcoded conference with dynamic bandwidth
allocation, encryption, and People+Content on the MGC, the
PVX system reports packet loss. To avoid this problem,
disable dynamic bandwidth allocation for calls using the MGC.
Calls using a 128 kbps continuous presence SIP conference
room on the MGC+H29 connect as secondary mode. To avoid
this problem, set the MGC’s video algorithm to H.263 and set
the video format to a format other than Auto (for example, CIF
or QCIF).In a 384 kbps call that uses a continuous presence
meeting room on the MGC, the transmit rate does not go
above 70 kbps. In a 384 kbps transcoding multipoint call that
uses People+Content on the MGC, the people transmit rate
drops when the system receives content.

Product
Issue
Polycom PathNavigator
Users may experience an audio screech when in a
Conference on Demand call. This is caused when one or
more of the conference parties are placed on mute. To correct,
users should unmute the far sites.
If you designate a PathNavigator version 5.0 or 6.0 address
as your system gatekeeper, call forwarding settings will not
automatically be reestablished when you close and then
reopen PVX. This problem does not occur with PathNavigator
version 7.0.
Call transfer cannot currently be used when you are in a call
using Conference on Demand.
T.120 is not supported in a Conference on Demand call.
Users may experience poor video quality when only one
endpoint is using PathNavigator 5.0. Use one of the following
options to correct this:
Register both end points with PathNavigator 5.0.
De-select PathNavigator and reestablish the call.
Polycom ReadiManager™
SE200
Systems that unregister from an SE200 gatekeeper may not
be purged from the gatekeeper list. Systems registered to a
SE200 gatekeeper may still be able to call the unregistered
system.
Polycom SoundPoint IP
600 and IP 4000
Calls to Polycom SoundPoint IP 600 and IP 4000 phones
version 1.5.2 are not supported.
Polycom SoundPoint IP
301, 501, and 601
In SIP calls placed from a SoundPoint IP 301, 501, or 601
phone to a PVX, the SoundPoint may not receive audio from
the PVX. Calls from PVX to the SoundPoint experience
normal audio. In order to insure proper interoperation, the
SoundPoint IP phone must be configured to use only G.711
uLaw and G.711 aLaw. G.729 A/B should be disabled, and
G.711uLaw should be the preferred audio algorithm.
Polycom V2IU
Calls received from an endpoint using a Polycom V2IU 5300E
version 5.4.1 will display an incorrect system address in the
PVX address book if added when prompted at call completion.
The correct endpoint dialing information should be entered
manually to the address book.
Polycom WebOffice
Polycom WebOffice 6.0 is currently compatible only with
ViaVideo version 5.1. Interoperability with Polycom PVX
software may be addressed in a future release of WebOffice.
RADVISION ECS
Gatekeeper
Encrypted calls through a RADVISION ECS gatekeeper may
connect without audio or video.
RADVISION viaIP Gateway
A loud tone may be heard from PVX systems when
disconnecting calls from a RADVISION viaIP Gateway.
Content sharing using H.239 or People+Content is not
supported in PVX calls placed through a RADVISION viaIP
Gateway version 4.0.

Product
Issue
RADVISION viaIP MCU
Calls through a RADVISION viaIP MCU version 3.2.38 may
connect without video.
Calls placed from PVX through a RADVISION viaIP MCU may
appear to be fully encrypted when they are not. Data on the
PVX statistics page may indicate that far end camera control,
video, and audio channels are encrypted, when only the PVX
channels are encrypted.
Sony G70
PVX does not receive H.264 video in calls with the Sony G70.
Sony PCS-1600
Users will experience an audio only call when connecting to a
Sony PCS-1600 video conferencing system.
Sony PCS-1 with H.264
Some Sony PCS-1 systems will not decode a Polycom PVX
H.264 video stream if the format is not exactly CIF. Sony has
been made aware of the issue.
In any call with the Sony PCS-1, PVX sends 30 fps and
receives 15 fps.
Tandberg Gateway
Calls through a Tandberg Gateway version G2.1 may send
video to PVX at algorithms lower than that at which PVX is
transmitting. For example, PVX may transmit H.263 video, but
receive only H.261.
Tandberg 880 MXP
In calls with a Tandberg 880 MXP with H.239 enabled, content
may continue to display on the Tandberg system even after
content sharing has been terminated. To correct this,
disconnect the call and redial.
In calls with a Tandberg 880 MXP versions B9.2, E4.2 & F2.5
with H.239 enabled, video may transmit at only 50% of the
dialed rate.
Tandberg 6000 E
Tandberg 6000 E systems may not display far-site video if
H.239 is enabled on PVX when the call is connected. To
correct this, disconnect the call, disable H.239 on PVX and
redial.
In calls with a Tandberg 6000 E with H.239 enabled, content
may continue to display on the Tandberg system even after
content sharing has been terminated by PVX. To correct this,
disconnect the call and redial.
VCON Escort
Users will experience corrupted audio when a call is made
from Polycom PVX to a VCON Escort at 64 kbps.
VCON HD3000
PVX is unable to send content to the VCON HD3000 when
H.239 is enabled. In H.239 calls with the VCON HD3000, PVX
is unable to transmit or receive H.264 video.
VCON MXM Gatekeeper
The VCON MXM Gatekeeper does not currently support the
Send Desktop feature in Polycom PVX.
The VCON MXM Gatekeeper may fail to successfully register
a Polycom PVX endpoint upon the initial registration attempt.
Repeating the registration process typically proves to be
successful on the second attempt.
