Also, with default interval (15 sec) pjsip STUN keep alive uses 10MBytes per day (300 Mb per month...) --- ???????? ????????? --- ?? ????: "R?gis Montoya" <r3gis.3r at gmail.com> ????: "pjsip list" <pjsip at lists.pjsip.org> ????: 27 ??? 2011, 15:04:55 ????: Re: [pjsip] Why STUN keep alive is needed? I think that reading this ticket will reply your question ;) : http://trac.pjsip.org/repos/ticket/539 IFAICT there is already something in 2.0 branch about that. (when I made tests about video I noticed that RTP transport was started only when necessary but didn't dive more into this point). And this will be very cool when there for Mobile SIP clients cause keeping STUN alive drain battery. Le 27/05/2011 10:16, ??????? UkrNet a ?crit : As I think, STUN transport and it keepalives needed only when calling. Why PJSIP sends keepalives always? Why do not open STUN ports just before calling? In this case STUN keep alive is not needed at all. Why not make STUN and SIP event exchange? I am not right? _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org -------------- next part -------------- An HTML attachment was scrubbed...
