So we have a box that's bound to all interfaces on the server, and one specific IP
address (that is an HA IP), and I've run into a bit of an odd behavior that I cannot
explain.
For 99.9999% of our traffic, the invites come into the HA IP, and then are forwareded out
the HA IP to an SBC for further processing. In a very rare instance however, I have found
that there is an invite coming in the HA IP, and for some unknown reason it gets forwarded
out the *interface* ip instead of the HA IP.
For example:
Working:
1.2.3.4 -- invite --> 9.8.7.6 (ha IP) -- invite --> 5.6.7.8 (sbc)
Non working:
1.2.3.4 -- invite --> 9.8.7.6 (ha IP) *something happens here* 9.8.7.5 (interface IP)
-- invite --> 5.6.7.8 (sbc)
I've been through tm, tmx, and the incoming invite of a working and non working
request with a fine toothed comb and I cannot for the life of me explain this behavior.
Any thoughts?

Does the behaviour differ depending on whether ‘mhomed’ is on?

I take it you have listeners on both the interface IP and the HA IP?
Absent ‘mhomed=1’, do you regulate egress interface selection for all t_relay() cases with
$fs explicitly? If not, try that.

apologies, I missed the second half of your post. We do not, and I know I could
explicitly tell it to use that IP, however I am more interested in figuring out what might
cause it to decide to use the interface IP, seemingly without a clear reason. I am not a
fan of static configuration of things like that in shared environments.

Understood, makes sense. I am not sure if outbound listener selection is entirely
deterministic, though, in the absence of either clear routing table feedback via mhomed or
explicit steering via $fs.

For example:
Working:

Non working:
1.2.3.4 -- invite --> 9.8.7.6 (ha IP) *something happens here* 9.8.7.5 (interface IP)
-- invite --> 5.6.7.8 (sbc)
I've been through tm, tmx, and the incoming invite of a working and non working
request with a fine toothed comb and I cannot for the life of me explain this behavior.
Any thoughts?

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

Absent ‘mhomed=1’, do you regulate egress interface selection for all t_relay() cases

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

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.

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

apologies, I missed the second half of your post. We
do not, and I know I could explicitly tell it to use that IP, however I am more interested
in figuring out what might cause it to decide to use the interface IP, seemingly without a
clear reason. I am not a fan of static configuration of things like that in shared
environments.

Correct.
listen=lo:5060
listen=eth0:5060
listen=eth1:5060
listen=XXX.XXX.XXX.XXX:5060 (<--- HA IP)

I take it you have listeners on both the interface IP and the HA IP?
Absent ‘mhomed=1’, do you regulate egress interface selection for all t_relay() cases
with $fs explicitly? If not, try that.

Does the behaviour differ depending on whether ‘mhomed’ is on?

out the *interface* ip instead of the HA IP.
For example:
Working:
1.2.3.4 -- invite --> 9.8.7.6 (ha IP) -- invite --> 5.6.7.8 (sbc)
Non working:
1.2.3.4 -- invite --> 9.8.7.6 (ha IP) *something happens here*
9.8.7.5 (interface IP) -- invite --> 5.6.7.8 (sbc)
I've been through tm, tmx, and the incoming invite of a working and non working
request with a fine toothed comb and I cannot for the life of me explain this behavior.
Any thoughts?

I also wonder of this is some weird misbehaviour related to the mixture of
by-physical-interface and by-address listener declarations.
