It also appears that YaTE is the same way. that one was a little easier 
to set up, but it's the same old song and dance: REFER trips it up every 
time.

I really wish sipXbridge was stable for me. Even with patch20 I drop to 
one way audio on my local LAN after about 5 minutes and locations that 
are just a couple of milliseconds ping away from the bridge software 
drop calls completely after a couple of minutes, and it's not my Adtran 
router, even when I'm bridging to other SIP devices this happens. I've 
sent Ranga a snapshot before but because we thought it was my Adtran 
router it never went anywhere. perhaps I should submit a bug with , or 
do you still have my original snapshots Ranga?
