Setting Up Video Endpoints
126 Avaya Video Telephony Solution Networking Guide
This section describes how to configure a Polycom MGC video conferencing bridge platform as
an H.320 gateway.
Before performing the procedures in this section, make sure the MGC is already administered
and registered to an Avaya Communication Manager system with inbound and outbound trunks
correctly configured per the instructions in Configure Polycom MGC Video Conferencing Bridge
Platforms with Avaya S8500 and S87xx Serveron page 82.
Trunk Groups
If the MGC is set up with outgoing and incoming trunk groups, you must create one incoming
trunk group that may map to many signaling groups with one signaling group per IP board. This
trunk group is the “incoming and gateway” trunk group.
Set the following parameters for the incoming and gateway trunk group:
●Direction to two-way.
●Service Type to tie.
●Disconnect Supervision - In? to y.
●Outgoing Display to y.
●Send Calling Number to y.
●Format to private.
This incoming and gateway trunk group may consist of trunk members associated to many
incoming and gateway ARQ+RRQ signaling groups. As result, the outgoing call traffic will
spread across all signaling groups and IP boards.
