Hello,
I am new to Kamailio and to the Kamailio Mailing list and hope I am using it appropriately.
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> [core/tcp_main.c:2660]: tcpconn_1st_send(): connect 172.1.1.13:59794 http://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,
