Do you have G726-40 enabled in global_codec_prefs in vars.xml? On Tuesday 26 January 2010, Joseph L. Casale wrote:
INCOMPATIBLE_DESTINATION usually means codec-related problems. Perhaps SPA offers G729 codec only and the codec name in SPA settings is set to G729a?
I think you narrowed it down:) After following the cisco docs for days to get rid of echo unsuccessfully, we were horsing around and changed the codec from G711u to G726-40 and the echo disappeared. Blank stares were met with a shrug. The firmware was updated but no powerdown was done and a test yielded it still working so we left it. The only change was a powerdown recently.
The output leading up to the hangup is:

So if I gather from this correctly, fs doesn't even have a codec to match against it?
Thanks a ton for the insight Sergey, jlc
