As the OP of this thread, I was more concerned that trunk=yes was not
actually placing two simultanous calls in the same packet and I had
included the parameter jitterbuffer=yes in that same post. Having been
on the list for over a year, I've read your (and other) postings
relative to the jitterbuffer, but I've not seen much in terms of 
whether trunking is or is not working in cvs head.

Looking at sniffer traces of two simultanous calls, its apparent that two
calls use two different udp packets. However, since I'm routing the two
calls via simple extensions.conf entries without reference to an iax
context, I was wondering if that _might_ be the root cause for this.
(Or, could it be that jitterbuffer=yes disables trunking.)

Any feel for that?
