ooh replying to my own posts again.  bad duncan.  some more information on 
the problems being encountered.

if i have an IAX2 Trunk - the person making the call cant be heard but the 
person recieving the call can hear them
if i have a standard call over IAX2 the person recieving the call cant hear 
anything but can be heard by the person making the call
if i have a standard IAX call - both sides can hear each other fine.

any ideas where the problem lies based on this new information?
