asterisk users - Feb 2005 - RTC Client (maybe VAD related)

Greetings,

I'm trying to create a server-based SIP chatroom (using MeetMe w/ 
ztdummy), where the clients will be mainly connecting with MS RTC 
Clients.  I got the authentication working, but am having a problem 
where I can only hear audio when I am also making noise into the 
microphone.  This appears to be the VAD/MOH problem mentioned on this 
list before.

This can be easily duplicated by connecting to the asterisk 'demo' 
extension using Windows Messenger (or any RTC Client).  No audio will be 
heard until you make noise, and then it will only play for a couple 
seconds before cutting off (until you make noise again).

I am aware the standard work-around to this is to disable VAD, however, 
with RTC this does not seem to be an option.  When MS is questioned 
about it, they usually respond, 'disable VAD .. why would you want to do 
that?'.

Can someone confirm that this is the problem I am experiencing?  Are 
there any other known work-arounds?

thanks in advance,
Tim Greiser

Double check transmit silence settings(if possible).  I could see that
happening if transmitt silence is turned off.
