Changing the default codec selection
About this task
By default, all B5800 Branch Gateway IP trunks and extensions use automatic codec
negotiation. The default negotiation order is G729(a) 8K CS-ACELP, G711 U-Law 64K, G711
A-Law 64K, and G723.1 6K3 MP-MLQ. G.722 64K is also available.
If bandwidth between the B5800 Branch Gateway and Avaya Aura
®
sites is sufficient, change
the first default preference to one of the G711 codecs. Note that the specific setting for
individual branch trunks and extensions can be set to override the system setting if
necessary.
