Anders,

Make heartbeat turn on kamailio service when there is a failover. And check the listen params in config file.

To be sure, check with netstat if kamailio is listening on the node IP.

Rgds,
Uriel

No firewall in front of the server (and nothing configured in iptables).

...I just found the problem: We use Heartbeat for a third IP to have
failover, but for some reason this thing doesn't like that specific
client's IP anymore. We can send calls directly to the Kamailio's IP,
but not through Heartbeat's IP. So, problem found - now we just need
to solve it.

Thanks for the input!
