Hi Daniel,
Thanks for a very quick response. The patch seems to work fine on
3.2.2. I will do some more testing later today.

Hello,
I committed a patch to remove maddr in fix_nated_contact() as it makes no
sense anymore if contact uri is updated:

If you can give it a try and all goes ok, then I will backport.
Cheers,

Hi Again,
For some reason my e-mail got truncated. Here is the complete e-mail:
I have this setup:
Mediation server with internal ip -- NAT firewall -- Kamailio proxy --
PSTN gateway
The mediation server sends a contact header with maddr=<internal IP>
fix_nated_contact only changes the host part and leaves the maddr intact.
When the PSTN gateway sends a PRACK or a BYE it puts the <internal IP>
in the RURI, and kamailio then try to forward the message directly to
the <internal IP> and not the NAT ip.
From RFC 3261 19.1.1:
The maddr parameter indicates the server address to be
contacted for this user, overriding any address derived from
the host field. When an maddr parameter is present, the port
and transport components of the URI apply to the address
indicated in the maddr parameter value. [4] describes the
proper interpretation of the transport, maddr, and hostport in
order to obtain the destination address, port, and transport
for sending a request.
I can see that OpenSIPS has fixed this.

Would it be possible to get this patch into Kamailio also?
