	You are missing the point completely.  Maybe I did not explain myself
clearly.  The problem is that when you connect to the server from
outside the network (Internet), Asterisk does not see the IP address of
the device, it thinks the device is connecting from the IP address of
the router itself (192.168.X.X).  This means that even if you have
externip, nat=yes and localnet configured properly, Asterisk will think
that the phone is on the internal network (because of localnet) and will
NOT use the external IP address to communicate with the external phone.

	This is not a problem with Asterisk.  The router rewrites all external
connections with its own IP so even a SSH connection will seem to be
coming from the router (the 'w' command will say you are connected from
the router and not from the IP address of your Internet connection).
