We have a problem connecting to a Cisco AS5300 trunk.
We set the sip peer to allow only g729. The call attempt is able to connect, but when answered, no audio is heard or transmitted. The only codec that can be used for this trunk is ulaw.
Our asterisk version is 184.108.40.206 . Codec is licensed, bought from Digium.
We do not have this problem on our other providers using asterisk and other non-cisco systems.
Anyone else having this same problem?
