Well, you *can* use the proxy to provide near-end NAT traversal.  The 
UAC module won't help much here;  your best bet is to statefully relay 
the REGISTER messages and the corresponding challenges.  There is a 
"nathelper" module that can help you fix up the contact bindings if it 
they contain RFC1918 addresses.

However, it should be emphasised in no uncertain terms that your UAC 
(Asterisk) must originate the request and relay it through the proxy; 
the proxy cannot originate it itself.
