Summary:                    ChanSpy Whisper not working properly when peer has
VAD and CNG on.
Description: 
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.
