[Kamailio-Users] NAThelper and multipart SDP

[Daniel-Constantin Mierla]

Hello Pascal,

I have just committed support for multipart bodies in sip router, if 
works then I will backport to 1.5.

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=1f41271e1c1b879217835b8b3fdbdc2680138f25


Can you test it? Unfortunately I cannot do it these days properly due to 
traveling. Patch should work pretty straightforward with 1.5 though, if 
you want to test it directly there.

Cheers,
Daniel
