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/kamailio-minimal-proxy.cfg*
<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.

If your clients will be registering/calling from a private net, then you
need to add that interface, i.e.:
listen=udp:192.168.6.2:5060
listen=udp:10.50.185.2:5060
alias=192.168.6.2
alias=10.50.185.2
this will allow kamailio to serve requests on both interfaces.
But this is not all you need, you also need to install and configure an
rtpproxy that will proxy the RTP streams.
Hope that helps
