It has been in JIRA for a long while, and has finally come up to be considered. There were some changes that I wanted to made to the original patch, so I tried contacting the author to get them to put the patch on reviewboard, but after a week I got no response. So, I'm putting the original patch up, then will immediately add a review with my changes. Many thanks to pedro-garcia for his contribution.
>From the JIRA issue:
I have some devices in the following scenario:
Asterisk server with public IP address
Mobile devices (clients):
When in internal network, no NAT between the client and the server
When in "roaming" (i.e. a Hotel with WiFi), the client is behing a NAT
When in 3G, operator transparent sip proxy so it looks as no NAT, but does not support symmetric RTP.
Sometime, the device gets a public IP with no NAT at all.
No NAT setting available in asterisk works for all these scenarios at the same time, and I can not request the user to activate different accounts depending on its location.
I have added a new NAT setting (nat=auto) to the current ones. When set, chan_sip auto detects from the Via header, the recv sockaddr, and the rport setting if the client is behind a NAT.
It also adds to cli interface results (sip show peer/s) info on this (so now you could see "N" for NAT and nothing for no NAT as before, "a" for auto detect no NAT, and "A" for autodetect NAT.</pre>

I also set the nat_supertest in testsuite to run with nat=auto to make sure that it responded the same with existing and non-existing peers.</pre>
