Hello
I have a Kamailio running behind NAT, which sends calls to a VOIP service provider.
I have setup the Kamalio to listen on port 5071, and also setup a port forward in the router.
Now the problem is that with TCP, 5071 is not used for the dialog, but a new port is chosen everytime. This means that when the mobile phone called hands up, I never sees the BYE, because BYE is a new dialog.
To which port is the server supposed to send the BYE, and what field tells the server this.
