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!

+Mark

Thanks for the help.  I'm working on a clean log.  We had many outgoing calls at the same time, the console log is mixed up with other calls.

Digging more into our logs, it seems the issue is sporadic: 50% of the time we can connect to a switch offering only PCMA, and other times we only offer PCMU and get this codec negotiation error.  The configuration has not changed across calls:

 <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G722,PCMU,PCMA,GSM"/>
 <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,GSM"/>

I'll work on a console log and sip trace.  In the meantime, any idea what could cause variation between calls in the codecs offered?

We would need to see a full siptrace and console log to see what's
happening here.

The carrier offers PCMA, and it looks like Freeswitch refuses to accept
anything but PCMU:

However, our codec settings in vars.xml specify:

 <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G722,PCMU,PCMA,GSM"/>
 <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,GSM"/>

The sip profile uses these settings.  Any idea how to debug what codecs
Freeswitch is willing to accept?

Thanks!
