Re: [SR-Users] User offline

Hello ycaner! Thank you very much! Now, what I think is maybe I should setup a rtpproxy server first, and then modify some configuration in pcscf.cfg and kamailio.cfg. But I will do a study into the reference you give me first. -- View this message in context: http://sip-router.1086192.n5.
