Hi Marshall,
I am creating a new thread for this.
Since there is lack of documentation currently, I am providing you the
next best thing. I coded a template user agent and demonstrated how to
do outbound calls. Attached is the cxx file. I have compiled and
tested this code to be working using the current opensipstack in CVS.
HTH,
