Note: Enter change ip-codec-set and enable the Allow Direct IP Multimedia field. In
Communication Manager 6.0.x, there are two options: normal users and priority

Allow reasonable inter-PBX network connectivity rates.
Avaya recommends that inter-PBX network connectivity be less than 150 ms end-to-end
one-way delay and less than 1% packet loss at all times. Otherwise, expect slower call
establishment. Compared with audio-only calls, multimedia calls have a greater number of
round-trip signaling messages by a factor of 5.
