[Freeswitch-users] Trouble w/ incoming calls from gateway

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,
