asterisk users - Feb 2006 - Comfort noise support incomplete in Asterisk (RFC 3389)

Hi guys,
I'm using Zyxel Prestige 2602R, as router/SIP-ua with my architecture
SER+Asterisk.
Normally, everything is fine. In these days I'm experiencing some problems:
some guests said me that, if he call everything is right, but if is called,
he cannot hear the caller.
Immediately, I though into an RTP-Proxy problem, but is not.
Then I saw that message appear on the Asterisk CLI, during the incoming
call:
NOTICE[3575]: rtp.c:330 process_rfc3389: Comfort noise support incomplete in
Asterisk (RFC 3389). Please turn off on client if possible. Client IP:
XXX.XXX.XXX.XXX
Now I've checked into the router, and the VAD was already unset.
Using normal IP-telephones, everything is perfect.

Does anyone, got an idea or already got problems with that router?

Thanks to all

same for me & ci$co router via chan_h323 (a have vad disabled on voip 
dial-peer on router),
but I'm ignoring this notice messages from asterisk console and logs, 
because calls are not disturbed ;-)

Can anyone explain to me what this means:

Jun 14 19:46:10 NOTICE[7391]: rtp.c:331 process_rfc3389: Comfort  
noise support incomplete in Asterisk (RFC 3389). Please turn off on  
client if possible. Client IP: 66.175.1.1

When I try to make a call from certain IP phones, I see that message  
on the console.

Thanks,
Daniel
