[Freeswitch-users] ILBC takes precedence regardless of the codec prefs

[Steven Ayre]

In your example FS is selecting the G711 alaw (PCMA) '8' codec. The client
offers it, the FS reply only returns the codec it has selected.

Try a debug level log of the call. It will show you a description of the
codec negotiation.

If you're not expecting the G711 codec to be accepted, check your codec
preferences. Inbound and outbound are separate parameters, and if you're
setting it from vars.conf.xml that sets a variable used in the sofia
profile... the profile could be using a static value that's different.

There are also other parameters that'll have an effect on a bridged call
such as late negotiation which would leave codec selection it up to the
bleg.
