6. Your problem:


I try to configure 2 SIP Servers in High Availability mode.
Both of them configured in the same LAN (behind SBC).
I have no problems, when a primary one is down, so the secondary server takes his role.
But, when a primary servers goes up (after reboot for example) I have IP address collision, when actually a VIRTUAL IP Address is configured on both servers.
How can I resolve the issue?

[hope]

before start up primary server, unplug the internet cable and remove virtual ip manually
if failover happens because of network problem, primary is still running
use heartbeat on primary serve to monitor network status, and add action to delete virtual ip from primary server when heartbeat fails.

Thanks for your reply.
Yes, if some temporary network problem between Primary and Secondary occurs, such a heartbeat action on primary will help, BUT most common failure is actually Primary/Secondary server sudden reboot for some reason, so AUTOMATIC solution for such an issue is very important (and not a manually that you specified).
