Yes, it sounds like there's a discontinuity in the timestamps when you 
set up your call, but it seems Dan can't reproduce this.

The fix is probably:

a) The jitterbuffer needs to be reset after the transfer, or
b) The timestamps sent need to be reset after the transfer.
c) Some changes to the jitterbuffer to automatically reset when it sees 
this kind of discontinuity.

(c can probably be combined with a and/or b).

I forget if you tried setting "notransfer=yes" on asterisk to see what 
that does?

What would really help, though, is a packet trace of the call.   The 
best way to get this is to use either ethereal or tcpdump.  (there is an 
ethereal for windows). 

If you use ethereal for Windows, have it capture all udp, make the call, 
and have it stay up for about 30 seconds, and save the file.   You can 
then send that file to me, and I'll be able to see what's going on a lot 
better than guessing here..
