Hi
I have two network interfaces on my system in which one interface is connected to my office WAN/LAN and other is connected to SIP private network connected to PSTN.
Now, I want to access sip server using the internal IP of our office LAN as proxy.
*192.168.6.2 (Office LAN IP as proxy) -> 10.50.185.2 (SIP)*
So on machine 192.168.6.2, I setup kamailio as SIP proxy server so that our office LAN machine can connect to SIP server directly via SIP proxy.
I used config defined in - *https://github.com/kamailio/kamailio/blob/master/misc/examples/mixed/kamaili... https://github.com/kamailio/kamailio/blob/master/misc/examples/mixed/kamailio-minimal-proxy.cfg and I changed the local domain alias with SIP IP -* 10.50.185.2*.
When I try to connect to SIP via proxy using *linphone* (UDP) I got below errors in* /var/log/syslog* and shows *connection in progress* every time.

Can you help me what I should do?
