The thing is that it's all controlled by your gateway configuration. This is 
where you define where you find what. You must know the IP (or domain name  
and use DNS) of where the recipient is. If you are calling a local host you 
must know the IP. If you call an external host you must also must know his 
internet address. He'd have a redirect in his firewall that would route to 
his internal machine. You have no need/use of knowing what his internal IP 
address is. 

I've done all the above in many combinations.

I have one setup on CA and one in FL.

I have had CA call over IP to FL, then fwd the call to a local external land 
line and call right back in again on another land line. I have called and 
transferred calls to a local LAN phone as well as over the Internet.
