[OpenSBC] Phone registration from behind NAT to sipX behind NAT

[OpenSBC F. <ope...@op...>]

Ok, since I got everything else working today (with a help from Joegen), I figured I'd go for the last piece I really care about...  far-end NAT traversal.

I have been referring to Raymond's excellent work over on the sipX Wiki ( [SipXecs-OpenSBC Setup Guide|http://sipx-wiki.calivia.com/index.php/SipXecs-OpenSBC_Setup_Guide_for_Different_Call_Scenario] ).

It is my understanding that the Upper Registration page should be able to mangle/rewrite the registration requests forward in towards my PBX (which has a different domain name inside than what I have outside).

So all calls / registrations in to *@sipxecs.info should be rewritten to be *@xyzcompany.com.

I believe the remote registrations would be working now if my internal domain was the same judging by the log below.
