Configure Ad-hoc Video Conferencing for a Polycom MGC Video Conferencing Bridge Platform
Issue 3 January 2008 95
6. Set ID Range to the range of ports. These IDs correspond to the actual conference ID
numbers of meeting rooms configured on the MGC. For example, if you enter the range
1000 - 1003, you must configure 1000, 1001, 1002, and 1003 as meeting rooms on the
MGC. These meeting rooms are for Ad-hoc use only and must not be accessible via the
Unified Dial Plan (UDP). Note that Automatic Alternate Routing (AAR) and Unified Dial Plan
are not used to connect to these meeting room numbers. Conference IDs (and factory
numbers) are completely independent of the dial plan. As a result, you can set up several
video bridges with exactly the same conference IDs and numbers. (This will make it easier
for you to maintain configurations and swap hardware.)

Procedure 6: Configure the MGC System

On the MGC system, perform the following steps for Ad-hoc conferencing:
1. Create meeting room IDs that correspond to the ID range on Avaya Communication
Manager Video Bridge form, with each being video switching auto conferences. Determine
the ID length from the MGC system.cfg file.
2. Set 1*1 transcoding so cascaded conferences display properly.
Display Capacity for Ad-hoc Video Conferencing
To display the capacity for Ad-hoc video conferencing:
1. Use the display capacity command to access the System Capacity form.
2. Go to page 7. Ad-hoc Video Conferencing Ports displays the following Ad-hoc video
conferencing information:
- Used - the number of video conferencing ports currently in use.
- Available - the number of video conferencing ports currently available.
- System Limit - the total number of video conference ports in your system. (This is the
sum of Used ports and Available ports.)

Use the list video-bridge command to view the video conferencing bridges administered on
your system.
