Overview
This document provides detailed instructions to configure the LifeSize video components (video codecs, cameras,
and audio I/O devices) with the ShoreTel System, to use extension dialing and video interoperability. Video
interoperability is a new feature introduced in ShoreTel 13 whereby a Communicator user can call from/to a
Lifesize room system and establish a video session.
Please note that ShoreTel has verified interoperability with a single Lifesize model, the LifeSize Room and
software version for ShoreTel 13.
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
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 configurations of LifeSize system
components occur on the LifeSize codec.

Architecture Overview
With ShoreTel 13, ShoreTel Communicator for Windows video-calls to and from LifeSize. By calling into a
Lifesize device with an embedded MCU, it can also participate in a multi-party video session.
Media path is peer-to-peer both video and audio.

Requirements, Certification and Limitations
The following requirements apply to this application note:




Any LifeSize Room system with Firmware version v4.7.19.
ShoreTel 13
ShoreTel SIP phone license (one per Lifesize unit)
ShoreTel Standard video license (VGA, 640 x 480)
Please note that the high resolution license is not supported with third party video system. For information on
future HD video plan please contact your Area Sales Manager
A call between Communicator and Lifesize can use up to 600 kpbs. The bandwidth used will vary with the
level of image activity.
Caveats


ShoreTel systems do not pass along the Remote Mute Status of the LifeSize video communications
system.
Video (both desktop video and LifeSize video) requires that the user have an IP Phone MAC address as
primary port
o Video will fail if the SoftSwitch (i.e. a ShoreTel server, or "unassigned") is selected as your
primary port
o Video will work if your primary port is an IP Phone MAC address, even if you are externally
assigned to a PSTN number or the SoftPhone

Figure 1- Non supported configuration


You cannot dial into a room system by entering an IP address into Communicator. You simply need to dial
into the Lifesize extension.
The video Accept feature in Communicator presents caveat with Lifesize. If the user setting in the video
option is set as “Ask Me: accept video from others” and you receive a call from Lifesize, the call will be
established with audio first. When the Communicator’s user presses the “Accept” button in the call cell,
the user will be able to see the video from LifeSize but Communicator’s video stream is not displayed on
the LifeSize unit. This is a LifeSize defect. Please contact your Lifesize representative for further details.

Multipoint Video
Communicator supports a multipoint call hosted on the Lifesize unit if the latter offers an embedded MCU.

Figure 3- Multipoint sample
When connected to a LifeSizeembedded MCU, the LifeSize system can change views and change display parameters
for their TV-based view. But Communicator will alwaysbe given a "grid" display of all participants and cannot adjust
or change that view
TIP: If the LifeSize MCU is set to "auto-answer" then multiple ShoreTel Communicator users could create an ad-hoc
multi-party video conference without any assistance from the LifeSize room system.
Configuration Overview
The following general steps are required to integrate a LifeSize video communications system with the ShoreTel IP
phone system:
1. Using Director, configure the ShoreTel system as described in the next sections.

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.

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

Troubleshooting Tips
Symptoms : « I see a black video in preview Window »
Areas of investigation:


Graphics card issue – update the graphics card drivers through device manager
User may be using generic windows drivers for their camera. In this case the generic windows drivers
need to be deleted from device manager and the correct drivers need to be installed.
