[Freeswitch-users] enable-3pcc=proxy behavior

[Sharath Kumar]

Ok. You are right the =true works but It gives me the unpleasant side
effect of auto-answering the call even before the user has answered the
call. So I thought the =proxy will help and give me the control over
providing the answer by the user(200 OK) rather than Fs supplying it. Do
you know if I can hook up an API for generating the local SDP and setting
the m_sdp variable ? I can contribute it back if it useful for other FS
endpoint users who don't use verto. Or is this something that can be done
in verto ?
