INCOMPATIBLE_DESTINATION means a codec problem.

The remote SDP sends they're offerring PCMU and G729.

What codecs are you allowing, what codecs are you bridging with, and since G729 is on the list are you perhaps trying to transcode without using mod_com_g729+licenses?

Hi,

My client has been running FreeSWITCH with low call volume and has been stable for several months now. This Tuesday morning we switched all call volume over to FreeSWITCH and everything was running fine until this morning.

Out of the blue, *all* calls started rejecting with INCOMPATIBLE_DESTINATION.

Restarting FreeSWITCH fixed the problem. The version of FreeSWITCH is a trunk build from approximately 7/11/2013. Is this an issue that an update could fix? Could this be port starvation? Please assist, thanks.

Here's a snippet from the freeswitch log where the first occurrence of that error:
