Hello,

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

Subject: [SR-Users] Query on force_send_socket

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
