[Freeswitch-users] Configuring different codecs for internal and external calls.

Hi Brian,


No it does not do what I expect.


When I make outgoing calls from a Freeswitch extension (using GSM) and then
out to a gateway using PCMU everything works fine.


When I receive calls from the same gateway, the end point behind the gateway
can't hear me.


The GSM-PSMU (and viceversa) transcoding for outgoing from an endpoint
associated with a  Freeswitch  extension to the external gateway is perfect
but incoming there seems to be an issue.


Any ideas?
