Administering Avaya Aura® Communication Manager for video endpoints
Administering Avaya Video Conferencing Solution 6.0.1 Issue 2.1 April 15, 2011 61
Review page 2 of all the codec-sets to be used by video stations and video trunks. Ensure
Allow Direct-IP Multimedia is set to yes. Also ensure Maximum Call Rate for Direct-IP
Multimedia set appropriately considering the codec-set is used for inter-region where there are
bandwidth issues.?
10. Ensure Inter Region Video Bandwidth Management on the IP Network Region screen is
used across WAN links. Ensure appropriate video total bandwidth limits on the IP Network
Region screen are set correctly.
Note:
Note: Expect low-quality video if the entry is not appropriate. 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.
11. On SAT, enter change station n (where n is the station number) and set the following
parameters:
● IP Video : Y
● IP Video Softphone : Y
● Direct IP-IP Audio Connections : Y
12. On SAT, enter change signaling group n (where n is the group number)
administration is appropriate for video support. Review the signaling groups used between
Communication Managers, to Polycom MGCs/RMXs, and to SE200s. Set the following
parameters:
● IP Video : Y
● Direct IP-IP Audio Connections : Y
● Calls Share IP Signaling Connection : No, though this setting may be Yes between
Communication Manager servers.
13. Ensure the network-region value in the Signaling Group screen corresponds to an IP
Codec Set that supports video.
14. Also ensure the DSCP tagging provisioning is correct.
Ensure that DSCP parameters are provisioned for the network region to which endpoints
are registered. For Communication Manager Release 4.0: Polycom VSX 8.5.3 onwards and
Polycom MGC 8.0.1 onwards will automatically obtain DSCP parameters as configured in
the network region. All other endpoints should have DSCP parameters set manually to the
same values to which Communication Manager is set.
15. Ensure the network region of the Avaya IP Softphone is the same as the IP set. On SAT,
enter change ip-network-map and set the Avaya IP Softphone to be mapped to the
same network region as the IP set.
