[Asterisk-Users] SIP Nat Issue

[Chris Albertson]

Asterisk works perfectly fine in back of a NAT firewall, as long
as all of your SIP phones are also in back of that same fire
wall ;-)

Seriously, I'd fix this if I knew enough about SIP protocol.
Is anyone willing to write up what is required at the "bit and byte
level"?   One thing that could help is try this and report
findings:

X-Lite _can_ dail out to FWD through a firewall but Asterisk can't.
SO this gives us the perfect chance to compare the content of
outbound packets where we have a working and non-working example.

I'd look into hacking Asterisk to mimic the X-Lite generated
SIP protocol.  

Put the result on the wiki.  Doing this will greatly speed up
the fix.
