[Freeswitch-users] INCOMPATIBLE_DESTINATION

[Steven Ayre]

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?
