Hi All,
I'm using Kamailio version 5.1.9.
In cfg file have routing to send out SIP messages from Kamailio stack. In
this routing logic added
force_send_socket("tcp:192.168.40.10:5060");
forward()
I'm expecting the send port should be from 5060, but it always pick
random port to send out message.
my requirement is to send SIP messages from 5060 port instead of picking
random port.
Regards,
Amarnath

Hello,
try this setting, it will force to re-use the same TCP port:

TCP doesn't work like that. Port 5060 is already bound to a listen()ing
socket; any new TCP sockets for outbound connections initiated would
have to bind to a different local port.

Unless it’s a reply, in which case the socket should already be
established, right?

Indeed -- if I understand you correctly.

Kamailio will use an ephemeral ports (assigned by the kernel) when making
outbound TCP connections, this is recommended for several reasons.
You can google "bind before connect", if you want to find out more about
this concept in Linux socket programming, this can be done to force the
source port on outbound TCP connections.
But comes with some unwanted limitations.
