Hello,
I entered this question before but did not include the tcpdump file. I am re-posting
just in case this message was over looked for lack of information.
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.
My server name is vadev2 (Kamailio run on this server), and it's IP Address and port
are 172.21.1.108:5060; Asterisk servers are (172.21.1.97:5060, and 172.21.1.124:5060).
The rtpproxy is 172.21.1.108:17722
Issue: Every 10 seconds I get an Error message in the Kamailio log which says =>
Nov 13 18:10:55 vadev2/usr/local/sbin/kamailio[29188]: ERROR: <core>
[core/tcp_main.c:2660]: tcpconn_1st_send(): connect
172.21.1.108:59794<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, other
than I do not believe anything is going through rtpproxy; I can make calls and use sip
tools which pass requests through Kamailio to Asterisk. Does anyone know what could be
causing this Error? I do not understand what is trying to connect to what and why.
Should I be using rtpengine instead of rtpproxy? I did attempt rtpengine but it would not
compile due to missing json.h files.
Thank you for any help
-Steve
