That is my understanding as well, and the current configuration works that way for \
99.99% of the requests. It's just the random occasional "glitch" where it tries to \
relay from the interface IP instead of the IP it came into.
I will take a look at the process and socket lists, but to be honest I don't think \
it's going to provide much insight. This is a very intermittent issue, but frequent \
enough that it's causing issues.

Hello,
in case of UDP Kamailio should use the process which received the message to also \
send it out (if you do not use anything like forcing a particular send socket or \
multi-homed).
Anything unusual if you look e.g. with "kamcmd corex.list_sockets" ? Which Kamailio \
processes are processing the messages, e.g., if you compare the Kamailio log pid with \
the "kamcmd ps" output?
Cheers,
Henning

We are using UDP everywhere currently. TCP is on the roadmap, but not implemented \
yet except for xhttp_rpc communication.

Hello,
what is the outgoing transport protocol? UDP or TCP/TLS?
Cheers,
Daniel
