[SR-Users] ACK and BYE messages uses wrong socket.

3 Jul 2012

Kamailio 3.2.0
I am trying to setup kamailio to do the sip trunking. It  receive the sip traffic from
customer and then send it to carrier.
I have two NIC interface's assigned with three IP's:
Interface 1: ( Public IP's)
x.x.130.34
x.x.130.36  floating IP
interface 2: (private IP's)
10.10.1.31

.36 is a floating IP  assigned by Linux-HA (heartbeat/pacemaker).

I only want to use .36 to receive and send sip traffic.
I uses  force_send_socket() to send INVITE with .36 IP.  But the ACK message always want
to use .34 IP even the Route header has .36 in it unless I force it with
force_send_socket() .

How can I fix this problem?
See below for the SIP messages: (x.x.128.205 is customer IP, x.x.129.200 is PSTN gateway
IP)
