Well, here is my current patch to libiaxclient. As you will see, it does 
not support sending an URL from the client, just receiving URL which may 
be sent by * via Dial+URL (or Queue+URL), usefull in call center 
environment.
I don't really know how to best handle sending an URL from the client, 
but copy/paste/send seems ok to me.


Thanks,
