[Freeswitch-users] Codecs and things

[Ahmed Naji]

Hi Rupa,

Thanks for your feedback.

I am currently running proxy mode, but whenever I try to force G.729 on
in-bound and out-bound calls, I get an error in my logs to the effect the
G.729 is only a pass-through codec. Both originator and reciepient have
G.729 codecs.

Have you seen this before ?

Regards,

Ahmed.
