We have an AS5300 configured for VoIP.
Our gateway is as terminating gateway.
We only receive calls from several partners.
In this case, is codec autonegatiation on by default?
For example, if we have two partners where the first is sending calls with G723 and the other is is sending calls with CODEC G728, does our gateway by default can select G723 CODEC with the first partner and G728 with the second partner?
If the codec autonegotiation is not on by default, what command should we use in our gateway?
