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.

---------------------------------------------------------------------- 
I think this issue can be considered as major since 90% of the time
asterisk is being used on a call center setup, and 90% of the case VAD
can't be simply disabled on telco side for the same reason bandwidth
savings. This hold's true 100% all the time in my setup here in my country,


Provider here in the philippines whether small or large use this, yes they
suck all the time but this how it is.

It's just IMHO.
