asterisk users - Feb 2004 - Interrupted musiconhold sound when silence suppression is enabled

Hi,
 
I am a new player of the Asterisk. I have a strage problem with musiconhold
feature. Can anyone give some clues what might be the problem? A description of
the problem is as follows:
 
1. Call from Cisco ATA 186 without silence suppression, when I push the
"hold" button at the Cisco 7960 IP phone, the music plays just fine.
2. Call from Cisco ATA 186 with silence suppression enable, when I push the
"hold" button of phone, the music is annoying, it cannot play
smoothly. Sometimes, it plays well for a while, then there is a pause, then
plays again, then pause,...
 
Certainly, an obvious solution is to disable silence suppression, however, this
is unpracticable, because, sometimes, you might have no control of the remote
side. Thanks in advance.
 
George

* uses the incoming RTP Stream as a timing source for sending its 
outgoing Stream..  If the incoming stream is interrupted due to silence 
suppression then musiconhold will be choppy.  So in conclusion, you 
cannot use silence suppresion.

I guess this explains why the music-on-hold goes totally silent (and
fast-forwards) when I hit the microphone mute button on my 7960...?

Could this be tied to zaptel timing instead (like meet-me)?
