[Asterisk-Users] Remote SIP Connection using Asterisk // Cisco7940's

[Tom Rymes]

Have you tried setting the extension to nat=yes in Asterisk, and then  
enabling the "NAT Enable" and "NAT Received Processing Enable" on the  
phones? There may be a NAT in between that you do not know about, or  
it might help for unknown reasons, but it certainly cannot hurt to  
try! From my experience, you do not want to specify a "NAT WAN  
Address" for the phone, because that will limit you to only one  
working connection behind the NAT.

Again, you might have no NAT, but it can't hurt. This raises another  
question I have: Is there any reason to NOT specify "nat=yes" for all  
of your extensions, even if they are not behind NAT? From what I can  
tell, it will help if the phone is indeed behind a NAT, and will not  
hurt if it isn't.... (I assume that I must be missing something here...)
