[Serusers] Ser & RTPproxy does not change the SDP vodeo port.

by Amos Shahar

hi, I'm using ser 0.9.7 and RTPproxy 1.1 on diffrent servers. the ser.cfg is the nat-rtpproxy.cfg from the iptel site. I have 2 grandstream GXV-300 devices, each behind diffrent NAT, this setup is working fine for voice and RTP is relayed through the rtpproxy properly. The problem is that the video is not working, when ser gets the invite from device A and send it to device B, it change the audio port only but leave the video port the same as the port he got from device A. I'm not sure if it is an issue with the RTPproxy or the nat-helper module. any idea how to debug / resolve? do you aware of other versions of ser/rtpproxy that this setup should work with video? Thanks! Amos

[Kamailio-Users] no RTP randomly with rtpproxy

by Samuel Muller

A strange thing happens with RTP proxy since I compiled the v.1.2.0 release ... Radomly, (approx. 1 time per 10 calls) RTP proxy don't grab the caller's original source IP in the SDP ??? So I don't have any RTP, so no sound during the call. typical call schema : sip phone -> mitel ipbx -> kamailio -> audiocodes mediant 2000 -> pstn All the SIP headers and the SDP are ok each time ... the RTP ports are ok too, understood at each point. rtp proxy is launched with these options with a public IP address (and compiled with a modified port range) : /usr/sbin/rtpproxy -s udp:77.246.81.133 35000 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -l 77.246.81.133 -m 6000 -M 64000 kamailio is ok too in the config : kamailio IPv4 UDP sip.720.fr:46830-> rtpproxy.720.fr:35000 logs of RTP proxy (option -f to screen the debug) : # rtp ok : received command "29638_4 L 3962688592-61598521(a)10.33.146.4 77.246.81.136 35000 0_3962688592-61598523;1 1c1320846358;1" lookup on ports 6008/6010, session timer restarted pre-filling callee's address with 77.246.81.136:35000 sending reply "29638_4 6010 77.246.81.133 " caller's address filled in: 94.198.149.41:50186 (RTP) guessing RTCP port for caller to be 50187 # rtp not ok : received command "29571_2 L 3288148592-61598465(a)10.33.146.4 77.246.81.136 35000 0_3288148592-61598467;1 1c934295778;1" lookup on ports 6000/6002, session timer restarted pre-filling callee's address with 77.246.81.136:35000 sending reply "29571_2 6002 77.246.81.133 " and hop, no "caller's address filled in" ... it's exactly the same type a SIP call (with the same ip phone, etc...). I can precise that rtp proxy is running on the same machine that kamailio (v.1.4.4), but listen on a dedicated sub-if. Does someone knows something about that ? thanks ! .Samuel Muller. sml(a)720.fr

by Klaus Darilion

Hi! Does $branch(name) also handle the "main branch" ($ru, $du) as a branch, or will it handle only the additional branches? thanks klaus
