It is common to have multiple instances of Asterisk listening to the same 
port number on the same LAN.

It depends on the provider and your networking resources.

Some (most?) providers "know" where to send the call based on 
registration. Each host can register as many accounts with as many 
providers as desired.

Port forwarding can also solve a lot of problems.

Switching to IAX (with registration) makes most of these issues moot.

Thanks in advance,
