I believe thats the configuration you've done via 'crm' to monitor for 3 crashes (by default probably) - that means if you kill it it will try start the monitored application on the same node first and if fails in 3 attempts only then goes to the secondary site. (try inducing an error in kamailio.cfg file and then killing the kamailio)

Now using a VIP or not is your choice.

I can only assume that you want to monitor the Kamailio service and if failed launch it on the secondary server that's all. If that's the case then you don't need to define any FAILOVER-IP

You need to read more on configuring via the crm command to change this behaviour.

Here is an old blog post I wrote on this: http://saevolgo.blogspot.ca/2013/05/opensipskamailio-high-availability.html

Probably the reference link can help you for more detailed explanation.

OK, and could you use anycast routing ?
Your HA could be done with BGP using communities and bgp localpref.

One restriction to bgp anycast routing: your network should be stable (to preserve transaction and sip dialog).

Hello,

For failover IP, why could not use keepalived ? With a script monitoring, you can switch vip from one host to another easily.

More simple than corosync etc in my opinion.
