Hi,
I have a problem that I don't understand at all (yet another one ;-)).
One client has Asterisk (like many others) from where he sends calls to our Kamailio. It worked fine, until it suddenly stopped for no apparent reason on Friday. No changes in configuration on his or our side.
We can ping his server just fine, and vice versa.
On any INVITE he sends, he gets no, zero, zip response from Kamailio on our server. I wanted to figure out why, so I put an 'ngrep' on port 5060 for his IP on our Kamailio server, and I got...nothing. No communication at all on this port containing this IP. Why? I have no clue. The ping should show that we can communicate, and a 'ngrep' on his server shows that he sends plenty of INVITEs, but gets absolute zero response from our Kamailio box.
Any ideas where to look?
Thanks a lot in advance!
Sounds like Kamailio, as an application, is not receiving the INVITE in the first place.
Firewall?

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!

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
