Lifesize Video Communications System and ShoreTel v8.x IP Phone

Application Note
LifeSize® Video Communications System and
ShoreTel IP Phone System
This application note provides the details for integrating a LifeSize video communications system
with the ShoreTel IP phone system. This application note requires the use of ShoreTel v8.x,
which supports the integration of LifeSize components as SIP extensions.
For the purposes of this application note, a LifeSize video communications system consists of the
following components:
•
LifeSize codec
•
LifeSize camera
•
Audio I/O device, such as LifeSize Phone, LifeSize MicPod, or ShoreTel IP 8000
LifeSize cameras and audio devices are connected to the LifeSize codec. All communication
between the ShoreTel system and the LifeSize system occurs through the LifeSize codec. All
configuration of LifeSize system components occurs on the LifeSize codec.
Use of LifeSize equipment and software components are governed by the
conditions and terms of the LifeSize Communications End User License
Agreement.
Requirements
The following requirements apply to this application note:
•
LifeSize video communications system v3.5 or later
•
ShoreWare Server Software v8.x. (Versions prior to 8.0 do not support SIP extensions.)
•
ShoreWare SIP phone licenses
Limitations
•
ShoreTel systems do not pass along any INFO messages from the LifeSize video
communications system.
•
ShoreTel systems do not pass along the Remote Mute Status of the LifeSize video
communications system.
Configuration Overview
The following general steps are required to integrate a LifeSize video communications system
with the ShoreTel IP phone system:
1. Using ShoreWare Director, configure the ShoreTel system as described in the next sections.
2. Using your web browser, register the LifeSize video communications system with the
ShoreTel SIP server.
Notes for Users Upgrading from a Previous ShoreTel Version
If you upgraded from a previous ShoreTel version, a certain parameter may be visible in the Call
Control options. You must disable this parameter in order to properly configure the SIP
extension. To check for this parameter, follow these steps:
1. Using ShoreWare Director, navigate to Administration→Call Control→Options.
The Call/Control Options screen appears.
2. If the Always Use Port 5004 for RTP parameter is visible, disable the parameter.
3. Click Save to apply the change.
4. Restart the ShoreTel system in this order: restart all servers, then all ShoreGear switches,
and then all IP phones.
If you are upgrading from a pre-8.0 version of ShoreWare and you configured the system to
integrate a LifeSize device in a SIP Trunk environment, follow the next steps. Otherwise, proceed
to the “ShoreTel System Configuration” section.
1. Using ShoreWare Director, navigate to Administration→Trunks…→Individual Trunks.
2. Delete all of the individual trunks that are currently in use by the LifeSize video
communications system.
3. If you plan to use the extension number currently assigned to the LifeSize system, navigate
to Administration→Trunks…→Trunk Groups, select the trunk group for the LifeSize
system, and edit the Off System Extensions range to either delete the extension number or
exclude the number.
If you do not plan to use the SIP trunk group any longer, you may delete it. However, if any user
groups are currently using the trunk group, you must first remove access to that trunk group
before you can delete it.
ShoreTel System Configuration
This section describes how to:
•
Create a SIP Profile for the LifeSize video communications system.
•
Create a Codec List for the LifeSize video communications system.
•
Configure a Switch port to act as a SIP proxy.
•
Configure the Site to use high-bandwidth codecs.
•
Create a SIP Individual User extension for the LifeSize video communications system.
Creating a SIP Profile
1. Using ShoreWare Director, navigate to Administration→Call Control→SIP Profiles.
The SIP Profiles screen appears.
2. Click New to create a new SIP profile.
3. Provide input for the following parameters:
Name—Enter an appropriate name, such as LifeSize.
User Agent—Enter the following:
LifeSize.*
Priority—Set this to 100.
Enable—Check this box.
Custom Parameters—Enter the following:
1CodecAnswer=0
4. Click New to create the new profile.
Creating a Codec List
1. Using ShoreWare Director, navigate to Administration→Call Control→Codec Lists.
The Codec Lists screen appears.
2. Click New to create a new codec list.
3. Provide input for the following parameters:
Name—Enter an appropriate name, such as LS_codecs. You will use this name later when
you configure the ShoreTel site.
Codec List Members—Select the AAC_LC/32000 codec and click Move Up until the codec
is at the top of the list.
4. Click New to create the new codec list.
Configuring the Switch Port
1. Using ShoreWare Director, navigate to Administration→Switches.
The Switches screen appears.
2. Select the switch you want to use to connect to the LifeSize video communications system.
The Edit Switch screen appears.
3. Find the port you want to use and set the Port Type to 100 SIP Proxy.
If your installation requires more than 100 SIP extensions, configure more ports as
necessary. For example, two ports each set to 100 SIP Proxy provides 200 SIP extensions.
Alternatively, if the switch you selected has Built-in Capacity for SIP trunks, you can set
aside a number of ports for SIP extensions. Every 5 ports assigned to SIP trunks provides
100 SIP extensions. For example, a single ShoreGear 120 switch with all ports assigned to
SIP trunks can provide 2400 SIP extensions.
4. Click Save to apply the change.
Configuring the Site
1. Using ShoreWare Director, navigate to Administration→Sites.
The Sites screen appears.
2. Select the site you want to configure.
The Edit Site screen appears.
3. In the SIP Proxy area, ensure that the following parameters are set:
Virtual IP Address—Designate the static IP address that can be used as a SIP proxy for the
site in case of failure. If you do not set a Virtual IP Address, you can define only one proxy
switch.
Proxy Switch 1—Select a switch to serve as SIP proxy if the current site fails. Switches are
available for selection only if proxy resources are enabled on the switch.
Proxy Switch 2—Select a switch to serve as SIP proxy if the Proxy Switch 1 fails.
4. In the Bandwidth area, ensure that the following parameters are set:
Admission Control Bandwidth—Defines the bandwidth to and from the site. This
parameter is important because SIP devices may be counted against the site bandwidth. For
more information, refer to the ShoreTel Planning and Installation Guide.
Intra-Site Calls—Enter the codec list name you defined in the “Creating a Codec List”
section.
Inter-Site Calls—Enter the codec list name you defined in the “Creating a Codec List”

appropriate extension. You will use this number later when you register the LifeSize video
communications system with the ShoreTel SIP server.
