Hi Ted.

I managed to get it to work today.  These are steps I took.  

On my firewall I port forwarded 5060, 10000-11000 UDP to the internal
Asterisk box.

In the sip.conf file I made these changes:
nat=yes 
externip = public.ip.address

On the X-lite phone I pointed the SIP Proxy to the public.ip.address that
was set above in the sip.conf file.


Good Luck.
