[SR-Users] Kamailio $Rp variable showing wrong port

[Shahid Hussain]

Hi Daniel,
Please find the debug logs attached. You can refer OPTION message of
timestamp 18:43:35 though there are multiple request.

There is a line in log says tcp worker on 8080 though I have not specified
in kamailio.cfg.
Jun 24 18:43:35 localhost kamailio: 44(11820) DEBUG: <core>
[core/tcp_main.c:4517]: handle_tcpconn_ev(): sending to child, events 1
Jun 24 18:43:35 localhost kamailio: 44(11820) DEBUG: <core>
[core/tcp_main.c:4190]: send2child(): selected tcp worker idx:6 proc:42
pid:11818 for activity on [tcp:172.27.45.219:8080], 0x7fca749c2d60

Attached kamailio.cfg also.
