Developing and testing no XP (but I will be testing on Vista).

Real.

Sigmatel Audio (Dell Laptop)... I have

It only occurred when using the Topology setup,
which could quite easily be because I need to change / fix
something else.
I think it was network delays / jitter buffering rather than
audio driver problems. I was getting delays at the remote
device as well - which is not running the sipXtapi stack.
At this point I have to get a working prototype together
by the end of the week... so I will be staying with
the main branch, but using the CallFlowGraph code.
Thanks
