[SR-Users] Error when attempting to use rtpproxy

[Wilkins, Steve]

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
