Avaya 16-601423 manual † No. Expect call failures

Avaya Communication Manager Administration for Polycom MGC Systems

Question 8: Is the incoming signaling group to the Polycom MGC configured correctly?

“RRQ Required?” must be y. “ARQ Required?” must be y.

“Near end Listen Port” must be 1720. “Far end Listen Port” must be 1720.

“Trunk Group for Channel Selection” must be set to the trunk that uses the group.

†Yes.

†No. Expect call failures.

Question 9: If a Polycom MGC is to be used for six-party Ad-hoc video conferencing with Avaya Communication Manager Release 5.0, has the MGC been placed in a dedicated network region?

You must have:

-a dedicated network region for MGC use

-dedicated codec sets to infer the conference bit rates

Map the MGC to the new dedicated network region using the region field on the signaling groups connected to the MGC.

Ensure that you are using a codec set that reflects the correct conference bit rates for the MGC’s network region.

Use the change ip-network region command to ensure that all other network regions have direct connectivity to the MGC’s network region.

†Yes.

†No. Expect the MCU selection algorithms to make compromised decisions based on potentially incorrect inferred information from the codec-set conference bit rates.
