Release Notes
Polycom PVX Version 8.0.4
Polycom is pleased to announce the release of Polycom PVX™ version 8.0.4.
Polycom PVX version 8.0.4 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 8.0.4 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 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 8.0.4?

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 Configuring Video and Audio Devices for Use with Polycom PVX
document, available from www.polycom.com/support/pvx804.
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 Configuring Video and Audio Devices for Use with Polycom
PVX document, available from www.polycom.com/support/pvx804.
System Performance
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
is 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.
You can also adjust the way Polycom PVX allocates system resources between
PVX and other applications. To do this, on the Setup > General page, click
Performance. Choose one of these performance settings:
Setting
Description
Balanced
Good video without too great an impact on general
application performance.
Other Applications
More processing power for running critical applications
while reducing the processing allocated to people video
and audio.
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:

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 8.0.4 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.
For more information about the camera driver load, refer to the Configuring
Video and Audio Devices for Use with Polycom PVX document, available
available from www.polycom.com/support/pvx804.

H.263/H.263+ People Video
H.263/H.263+ video is scaled in a similar way to H.264. However, it is not as
efficient and it is not used at any call rate unless H.264 is disabled on PVX or
the far site does not support H.264.
For example:
•
On a 2.4 GHz Pentium 4, PVX will support 1920 kbps VGA/4@30fps.
•
On a 3.6 GHz Pentium 4, PVX will support 1920 kbps VGA@30fps.
The CPU speed for H.263/H.263+ video is 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.

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. Note that PVXSET is not supported on systems
running Windows Vista. 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 > Feature Enhancements.
PVXSET Utility
Note: Polycom does not support the PVXSET utility. PVXSET can be used only
on systems running on Windows XP.
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.

Release Notes
Polycom PVX Version 8.0.4
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.
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.

Release Notes
Polycom PVX Version 8.0.4
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.
•
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
PVXSET Feature Limitations
•
The following PVXSet features appear in the PVXSet sample file, although
they are no longer supported: Data Conference, ILS Directories, and IBM
SIP. Using these features causes undesirable behavior.
•
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.
•
When you use the PVXSET utility to set a property while PVX is shutting
down, PVXSET will fail to connect to VVManager.
•
When you use the PVXSET utility to set a property, none of the Out-of-Box
setup pages are shown.

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 Configuring
Video and Audio Devices for Use with Polycom PVX document, available from
www.polycom.com/support/pvx804.
Network Profile Management and Configuration
PVX enables users to specify different network settings depending upon the
location in which they’re using the system. System configurations can be set for
particular locations and the network settings can be saved as a named profile.
16
Release Notes
Polycom PVX Version 8.0.4
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
•
H.323 Page
— Use PathNavigator™ OneDial for gateway calling
— Dial Prefix
Creating .plcm Speed-dial Files
You can create speed-dial desktop shortcuts for PVX directory entries that you
dial frequently.
To create a shortcut on their desktop, and make a call, users can do the
following:
1. Click the Directory button on the main PVX page or on the Toolbar.
2. Click and drag any directory entry onto their desktop.
A new speed-dial icon will appear on the desktop. The filename will
correspond to the directory entry and will be appended with an extension
of .plcm.
3. To make a call to the entry on the desktop, either double-click the icon or
right-click the icon and select Call from the menu.

You can also manually create speed-dial files as text files with a .plcm
extension. To do so, use this format:
NAME=<Name Field>
SPEED=<Speed Field>
NUMBER1=<IP Address Field; can also be a DNS name>
NUMBER2=<not used; leave blank>
EXT=<H.323 Extension (E.164) Field>
SIP=<SIP Address Field>
ISDN=<ISDN Number Field>
This is a sample file named AnyUser.plcm.
NAME=AnyUser
SPEED=512
NUMBER1=100.100.100.100
NUMBER2=
EXT=
SIP=
ISDN=
When creating the speed-dial files:
•
The speed must equal one of the call speeds listed in the directory's Call
Rate list. These speeds can be configured by going to the Network >
Bandwidth page and clicking the Call Speeds button.
•
If you enter both a SIP and a H.323 number, PVX will dial the call using

Polycom PVX Version 8.0.4
•
Many Bluetooth® headsets only support telephone quality audio and
degrade the wideband audio feature in PVX. Consider the frequency
response and convenience tradeoff when using a Bluetooth headset.
•
You may notice an increase or decrease of the system’s audio volume level
when starting the Polycom PVX application.
Calling Issues
•
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.
•
When you save the far end's information to the Directory after a call ends,
the saved call rate is the default rate, regardless of the actual rate used in
the call. If a directory entry includes an asterisk (*), you can not drag it to
the desktop.
•
If you include “&” or “<“in any field of a directory entry, that entry and
any other entries added or modified during this session will not be saved.
•
In conference-on-demand calls among three PVX systems, some systems
may not receive video.
•
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.

Polycom PVX Version 8.0.4
•
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
Network Address Translator (NAT)/firewall devices do not. If you
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
21
Release Notes
Polycom PVX Version 8.0.4
far-site system is being prompted to accept or decline your incoming call.
PVX endpoints will not be prompted to enter a password.
•
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.
Global Directory Server
•
If you configure a password for a Global Directory Server and then delete
the GDS, the password is not deleted. This may interfere with registering
the system to another GDS. To prevent this problem, delete the password
before you delete the GDS.
•
When the Global Directory Server goes offline, the PVX system does not
display an alert until it is restarted.
Installation
•
Restoring the PVX to factory defaults does not reset the Auto-start
Application in Background setting if it was previously enabled.
Microsoft Windows Issues
•
Configuring the system to use an invalid Global Directory causes the PVX
system to freeze for several seconds on startup.
•
When you send content from a Windows Vista system with the Aero color
scheme enabled, the content frame rate is slow and the content can appear
blocky. To work around this problem, set the system to use another color
scheme, such as Vista Basic.
•
When you run Polycom PVX on a Windows Vista system with the
Windows Aero color scheme enabled, pressing Ctrl+Alt+Delete changes
the Windows color scheme to Windows Vista Basic. The color scheme
returns to Windows Aero when you close PVX.

If you have installed PVX 8.0.2 on your Windows Vista system, you must
uninstall it before you can install version 8.0.4.
•
When you record VideoMail on a system running Windows Vista and
using the internal sound card as the audio input device, clicking mute
causes video to freeze and recording to stop. If you change the audio input
device to a camera or a microphone, VideoMail records as expected.
•
When you enable Auto-Start Application in Background on a PVX
running on a Vista system, the PVX application may take up to one minute
to start.
•
On a system running Windows Vista, PVX does not display a camera alert
message when you disconnect the camera. PVX displays an alert when
you restart PVX.
•
In a call between Polycom PVX running on Windows Vista and a
Tandberg 880 system, the far end sees black video when PVX shares the
desktop.
•
When you run PVX in full-screen mode on the secondary monitor of a
dual-monitor computer, you may receive black video from the far site.
•
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.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).
Network Issues
•
When you place or receive a SIP call through a Netgear WGT624 router,
version 3, the call may not connect.
•
When you place a call from a PVX system running on a AMD Turion dual
core laptop, connected via VPN through a Cisco VPN concentrator
running with 128-bit AES encryption, the call crashes. Changing the VPN
encryption to 256 bits resolves the issue.
•
When you connect a USB device running Windows Mobile 5 (with
Activesync 4.1) to your computer, the device creates an ethernet adapter
with the address 169.254.2.2 and places it first in the network adapter list.
Because Polycom PVX uses the first adapter listed when it is configured to
use the Windows default adapter (on the Setup > Network > Connection
23
Release Notes
Polycom PVX Version 8.0.4
page), PVX uses the Windows Mobile 5 adapter instead of the LAN
adapter. To work around this problem, do the following:
1. From Windows, choose Start > Control Panel > Network
Connections.
2. From the Advanced menu, choose Advanced Settings.
3. Select the Windows Mobile 5 adapter, and click the down arrow to
move it below the LAN connection in the list of network adapters.
•
If you configure the system as Connected over VPN using the default
network adapter before you connect the system to the VPN, the system
displays a Network alert. This alert continues to display until you change
and reapply the network setting.
•
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. If you change the Media port
range on the Ports tab of the Setup > Network page and then upgrade to
PVX version 8.0.4, 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.
•
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

•
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

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

•
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.
•
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

not enable this setting. For important information about how to set this and other
settings to achieve optimum video quality, refer to the Configuring Video and
Audio Devices for Use with Polycom PVX document, available from
www.polycom.com/support/pvx804.
Polycom has qualified the cameras listed in the Configuring Video and Video
Devices for Use with Polycom PVX document available from
www.polycom.com/support/pvx804) 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.
•
On the Setup > Video > Advanced page, if you select Low or High in the For
the camera you have selected, specify the camera driver's load on the
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.
•
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 Configuring Video and Audio Devices for Use
with Polycom PVX document, available from
www.polycom.com/support/pvx804.
•
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.

Release Notes
Polycom PVX Version 8.0.4
•
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.

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.
Cisco Call Manager
Cisco IP phones do not disconnect correctly from calls
with PVX systems.
Check Point Firewall
PVX H.323 calls through a Check Point Firewall
version NG R55 may connect without audio or video.
Cisco VPN
When you connect to the VPN before you configure
PVX to use the Cisco VPN client, PVX displays a
network alert, though there is no network problem.
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.
ClearOne Chat 50
In a call between Polycom PVX and ClearOne Chat 50,
when either end mutes the call, the indicator on the
other end does not correctly show the mute status.

Release Notes
Polycom PVX Version 8.0.4
Product
Issue
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.
D-Link DI-624 router
When a PVX located behind a D-Link DI-624 router
calls a PVX that is registered to a PathNavigator in
routed mode, the call fails.
Ezenia! MCU
When using the Polycom PVX software with an Ezenia!
MCU version 6.0, AES encryption must be disabled.
Logitech Fusion camera
Using a Logitech Fusion camera with version 10.0.4
drivers increases the CPU utilization approximately
20% when compared to the CPU utilization with the
version 9.5 drivers.
Video sent from a PVX system using a Fusion camera
periodically displays bright white video artifacts in calls
experiencing packet loss.
Microsoft LifeCam
VX6000 camera
In calls using the Microsoft LifeCam VX6000 camera,
the PIP is displayed about 5-7 seconds after you
enable it if PVX is running on the secondary monitor.
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 router
A PVX configured to use a NETGEAR NAT receives
black video when the far end sends content.
Office Communicator
When you use Office Communicator to place a SIP call
to PVX through the LCS server, the audio and video
received by Office Communicator is out of sync is off by
about 1 second. Audio and video received by PVX are
in synch.

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 HDX
When you use Polycom HDX to initiate a SIP call
above 1920 kbps to Polycom PVX, PVX accepts the
call and connects at the specified rate, although PVX
does not support calls above 1920 kbps.
Polycom iPower
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.

Issue
Polycom MGC
In a video switching SIP conference through the MGC,
PVX connects in secondary mode.
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.
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.
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.
Users may experience poor video quality when only
one endpoint is using PathNavigator 5.0. Use one of
the following options to correct this:
36
•
Register both end points with PathNavigator 5.0.
•
De-select PathNavigator and reestablish the call.

Issue
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. When a SoundPoint
501 phone places an audio-only call to Polycom PVX,
the SoundPoint 501 does not receive audio. If the PVX
calls the SoundPoint system, audio works as expected.
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 ViewStation FX
When a ViewStation FX system downloads a
PowerPoint presentation from the ViewStation FX web
interface and sends it to Polycom PVX, the PVX
system does not open a browser to display the
presentation.
Polycom WebOffice
Polycom WebOffice 6.0 is currently incompatible with
Polycom PVX. 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
In an encrypted H.239 call through a RADVISION viaIP
MCU version 4.2.10, content sent from one PVX to
another is not displayed. To work around this problem,
turn off encryption.
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.

Product
Issue
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.
Venturi accelerator
software for Verizon
wireless cards
Systems that use vlsp.dll, a DLL that is part of the
Venturi accelerator software that is part of the
installation used for Verizon wireless cards, may
experience very slow PVX startup. To avoid this
problem, uninstall the Venturi software.
Windows Messenger
In calls between Windows Messenger and Polycom
PVX, the audio and video received by Windows
Messenger may be out of sync by about 1 second.
Audio and video received by PVX are in synch.
When you initiate a call to Windows Messenger version
5.1, PVX does not transmit audio. When the call is
initiated from Windows Messenger, PVX receives
audio as expected.
