Hi all I want to setup IP failover for Kamailio:
I have 2 hosts A (IP: X.X.X.32) and B (X.X.X.36), with 2 running kamailios. Using Keepalive to setup IP failover as , virtual IP *is X.X.X.43*.
On host A, kamailio was binded to *listen=udp:0.0.0.0:5060 http://0.0.0.0:5060* and host A is MASTER with virtual IP
*Problem is:* Client send REGISTER to X.X.X.43:5060. It recieved 401 respond from X.X.X.32:5060 (actual IP of A), not as expected from X.X.X.43:5060
(To check if keepalived setting OK or not, I have *nc -l 5060* on host A, and using nc X.X.X.43 5060 on client, wireshark show that responds is from X.X.X.43 -> keepalived work OK
Is there any difference between *kamailio* and *nc* cause they both bind to 0.0.0.0, but repond on differ IP?
Thanks
Vinh Nguyen
Hello, I've the same deployment.
And I don't have any problem,.. but in kamailio.cfg I setted the Virtual IP
listen=udp:X.X.X.43:5060
At least this is the Ip that should work.
I hope this help you.
Regards.

Hi, also you can choose the outbound socket to use by setting '$fs' pseudovariable or use "force_send_socket()" function.

Do not use "listen=0.0.0.0", because in this case Kamailio inserts this IP address (0.0.0.0) in proxy related SIP headers, which turns into errors from UAC. This behaviour seems like a bug. It would be interesting to see response from developers.
Just use "listen=X.X.X.X", where X.X.X.X is IP address you want Kamailio to listen on.
