Hello,
Im running kamailio 4.2.3 and I'm trying to build a system where I could have the following features: SIP proxy, RTP proxy, Presence & XCAP service for IM messaging.
I have a problem with the Presence service with users that are located behind nat. When Kamailio sends presence info to a watcher with sip NOTIFY message, the destaination ip for the pacage seems to be an un-routable (=private) ip, and so the watcher never receives the NOTIFY message making the watchers sip client unaware of the other users presence.
Any suggestions how to make Kamailio handle the watchers behind nat so that the NOTIFY messages will get delivered succesfully?
I tried the scenario with a client with public ip and the presence works fine.
my kamailio.cfg: http://tny.cz/7d85773c
