[SR-Users] Kamailio stop responding to AWS R53 health check

Thu Nov 14 15:04:17 CET 2019

Hi Daniel,

So first of all, R53 won't route anything over to this node as it marked as
"Unhealthy", which was the first indication there was something wrong with
this node.  It sends ping probes to tcp port 5060, which we saw was
listening on the Kamailio device.  Then we used other methods to test the
connection such as "telnet <IP> 5060" which usually should connect but it
didn't.  We ran this both locally and remotely which generated the same
result.  I even ran tcpdump to see what is happening.  All I saw was R53
ping messages come in, but no response going back out.  So I restarted the
Kamailio process and that fixed everything.

The TLS method used is TLS1.2:

method = TLSv1.2
