Kamailio and rtpproxy error and why do we need rtpproxy (example that works without it)

I am using Kamailio version 5.0.3 (x86_64/linux), and it is installed and working on a Centos 7 Sever. I use Kamailio as a SIP Proxy Server for Asterisk and things seem to work fine, however, I do have an issue and a question for which I am trying to understand and am hoping someone can help me with.

For the sake of the argument, my server name is myServer, and it’s IP Address is 172.1.1.13; Asterisk is on a different server.

Issue: Every 10 seconds I get an Error message in the Kamailio log which says => Nov 13 18:10:55 myServer /usr/local/sbin/kamailio[29188]: ERROR: [core/tcp_main.c:2660]: tcpconn_1st_send(): connect 172.1.1.13:59794 failed (RST) Connection refused.

I do not know what triggers this error, and as mentioned, things do seem to work; I can make calls and use sip tools which pass requests through the Kamailio to Asterisk. Does anyone know what could be causing this Error? I do not understand what is trying to connect to what at such a high port.

Question: The way I understand it, rtpproxy is needed to pass video/audio through Kamailio to Asterisk. However, even without rtpproxy running, I get video through to Asterisk and the video plays with no issues on a sip device (e.g. MicroSIP). I am confused what I need rtpproxy for. Note: Even with no rtpproxy, I get the same error mentioned above in the Issue section.

Thank you,

  • This seems like you have mentioned this connection port for some service within kamailio.cfg , so you should look into your kamailio.cfg and see why is it connection to 172.1.1.13:59794 and you'll know to why it's trying to connect .

  • RTPProxy or RtpEngine is used for the Relaying purposes and it can also do the crypto things between legacy SIP client and webRTC clients, however the latest module can also record the calls as .pcap or .mp3/.wav
