[cisco-voip] Tone On Hold for a conference bridge system

[Peter Slow]

That timer you are changing will not affect your h.323 gateway. if you
want silence on hold to that gateway, you need to do what i was
mentioning earlier using mutlicast.

your other option is using a blank audio file that you record and
upload. You MUST MAKE IT A DECENT LENGTH. don't upload a 5 second
audio file - i'd say 30 seconds is good. This unfortunately will also
affect MoH on the rest of your network, since you'd need to set this
as the source for all of your phones. The multicast thing we can do
without affecting other gateways or IP phones.
