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.

Re: [SR-Users] User offline

Hello,ycaner! Thanks for your advice! I searched nat_traversal in kamailio.cfg in PCSCF module, and found that I should define WITH_NATPING. After doing this, a new problem came. What does this line mean? What should I configure to replace "sip:keepalive@HOSTNAME" ? Is this HOSTNAME a turn/stun
