asterisk users - Dec 2004 - SIP and Windows Messenger

I'm trying to get two Windows Messenger clients to communicate with
video and audio though asterisk.  I'm running into one of two problems. 
I get garbled audio under the current config.  I had another config
where I could get a voice call to work but using video would cause the
caller to get music on hold.  (very odd)

Calling a phone hanging off of an TDM the audio works great.  This is
using the CVS code from 11/7/04.

I'm trying to do video conference Friday and everything from making this
work to H.323 (which is a pain anyway) isn't working out so well.

Thanks for any help,

Rob
