24 Avaya Video Telephony Solution Networking Guide
Question 9: Is the video administration correct in the ip-codec-set form?
Review page 2 of all the codec-sets to be used by video stations and video trunks.
Is “Allow Direct-IP Multimedia?” set to yes?
Is “Maximum Call Rate for Direct-IP Multimedia” set appropriately considering whether the
codec-set is used for inter-region where there are bandwidth issues.?
Yes.
No. Expect audio only calls.
Question 10: Is ip-network-region inter-region video bandwidth
management used across WAN links?
Ensure appropriate video total bandwidth limits on ip-network-region page 3 are set
correctly.
Yes.
No. Expect low-quality video. Avaya recommends replacement of CAC via trunk-member
counting with cumulative bandwidth management. Note that unlike audio, Avaya
Communication Manger’s bandwidth management feature does not take into account the
variable video headers. Allow 20% overheads. Best practice recommends video applications
should consume no more than 35% of the total WAN bandwidth.
Question 11: Is video station administration correct in the station form?
First refer to this guide or the quick setup guide.
Ensure “IP Video?” is yes.
Ensure “IP Video Softphone?” is yes.
On page 2, ensure “Direct IP-IP Audio Connections?” is yes.
Yes.
No. Expect audio only calls.
