Summary: I-D sip-outbound support

Initial Comment:
The most important standard for SIP signalling NAT traversal (as opposed to RTP media problems) is the upcoming Internet-Draft sip-outbound, ie. http://tools.ietf.org/id/draft-ietf-sip-outbound-02.txt

It basically asks the SIP proxy to keep the TCP connection alive that was used for the initial registration, and use that for signalling. Keepalives are used, either TCP, in-line or STUN requests.

OpenSER has great NAT traversal functionality, but proxy-side hacking can't be the long term solution. This seems to be it, and the draft is almost ready.
