Dear all,
I am using SER as IM server and I found that the SER use the contact field to storage the user's location in the memory for future requests. I noted this using the command "serctl alias show" and checking some traces. Since I'm using a NAT scenario I'd like to use the UDP port that my SER server receives during the registration instead of the contact field port to reach the users after their registration. Is there any way to do this?
"rport" does it, but the client must indicate support of "rport" by adding ";rport" parameter to its Via header. Anyway, *SER can force it by using "force_rport()".
Thanks Iñaki,
So bad that my client doesn't support rport. :-( I have been reading about fix_nated_contact(). Some one have some example of the ser.conf using this command? *

You need "fix_nated_contact" as well as "force_rport". There are lots of examples in internet about configuring it. Look for OpenSer/Kamailio/OpenSIPS/SER wiki/doc pages.
Dear all,
I'm running a SER 9.6 in order to handle IM and presence. IM are working just great. I have an issue with the presence. At the moment of receive a SUBSCRIBE message, the SER respond with a 400 BAD REQUEST and the message "Error while parsing headersServer: Sip EXpress router (0.9.6 (i386/linux))" inside. Any ideas? Thanks in advance for the help.
Daniel Serrano.
