[Asterisk-Users] NAT Asterisk Peering

[Dan Adams]

Is it better to use the IAX prtocol rather than SIP? When I was working 
with the company setting up the Asterisk server that will be on the public 
IP to myself I was
told that SIP works better in general and I had read on the voip-info 
website that it could be accomplished with SIP.

Also, I was wondering, how would it work to transfer a call to an 
extension in the asterisk server that is on the public IP? Wouldn't I 
specify that extension from my
own asterisk box?

I know and will admit that I am sorta a newbie, I have done some work with 
configuring an asterisk box that is already running.
