[asterisk-users] MOH question w/Cisco 79xx phones

I think in your SIPDefault.cnf you disable VAD

enable_vad: 0			; VAD setting 0-disable (Default),
1-enable

Hi Everyone....

Got a newbie type question regarding MOH & Cisco phones.

I'm still new to Asterisk (very new in fact) & built up a AsteriskNOW
box
just to get something going.

My simple test system has just 3 Cisco phones a 7905, 7940 & 7960. -
Everything's running SIP.

The 3 phones can call each other fine. - Can even leave (and retreive)
voicemail messages. - No problems.

My problem is with MOH (Music On Hold). - The 7940/7960 are "somewhat"
okay,
but the 7905 is another story.

When a is call from a 7940/7960 is placed on 'hold' (by the calling
party),
MOH starts up on the 7940/7960, plays for about a second or two, then
drops
out for about a second or so, then continues. - After that, it continues
to
play okay.

But when a call from the 7905 is placed on 'hold' (by the calling
party),
MOH starts up on the 7905, plays for a second or two, drops out for a
sec,
starts again for a sec or so, drops out, starts back up, drops out,
etc.,
etc., etc....  Just up and down. - Kinda' like a Yo-Yo.

Also - When the call from the 7905 is placed on hold, I see the
following
warning at the Asterisk CLI:
[Jun 29 22:18:28] NOTICE[3376]: rtp.c783 process_rfc3389: Comfort noise
support incomplete in Asterisk (RFC 3389). Please turn off on client if
possible. Client IP: 10.0.0.110

I don't see this warning when the 7940/7960 is playing MOH.

I'm using basic default settings for just about everything. - Could this
be
with the RTP config? - The 7905 Audio settings?

Anybody have a clue?

Thanks in advance.

Gary Guthary
