[Freeswitch-users] Error in codec negotiation: What are all the places that specify accepted codecs for outgoing calls?

Hi Kristian,
I've narrowed this INCOMPATIBLE_DESTINATION error down to a specific case:
1 - Freeswitch sends the outgoing call, and offers PCMU/PCMA/GSM
2 - Other end accepts only PCMU
3 - At some point after Pre-answer, the other end issues a 183 Session Progress, changing to only accept PCMA.
4 - Freeswitch attempts to select new codecs but only looks at PCMU, and cancels the call with INCOMPATIBLE_DESTINATION.
Here is the console log and sip trace... Hope it helps!
