> when I use a SIP provider with VAD/CNG that is always ON. firt of all I get this in the CLI:
> rtp.c:831 process_rfc3389: Comfort noise support incomplete in Asterisk (RFC 3389). Please turn off on client if possible. Client IP: 0.0.0.0
> which is normal and the call would work fine.
> the strange thing is when I ChanSpy on the call.
> A(Sping)
> B(Spied)
> C(Person on the other end of the peer.)
> A can hear B and C
> B can only hear A if C is not silent
> so it feels to me that in order for B to hear A there must be audio coming from C for asterisk to mix it in with A's audio.
