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 s=
ame time, and I can not request the user to activate different accounts dep=
ending on its location.

I have added a new NAT setting (nat=3Dauto) 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 no=
w you could see "N" for NAT and nothing for no NAT as before, "a" for auto =
detect no NAT, and "A" for autodetect NAT.


This addresses bug ASTERISK-17860.

ro-garcia. 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 origin=
al 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&#39;m putting the or=
iginal patch up, then will immediately add a review with my changes. Many t=
hanks to pedro-garcia for his contribution.
