[Freeswitch-users] Codec negotiation. Totally confused

Mon Mar 7 01:29:29 MSK 2016

Yep, tried to play with it, same idea, on external profile call - only
g722. Which is not even in outbound codec list. And, according to manual,
FS should offer all codecs in list to next endpoint, which is not happens.
That’s my main confusion…
