Greetings,
I'm having some problems with keeping the order of the messages in Kamailio.
In some cases i'm receiving an ACK for the first INVITE and immediately
after that a RE-INVITE is sent by the client.
What is happening is that the the ACK took double the time of the RE-INVITE
to process and as a consequence, the RE-INVITE was relayed before the ACK.
I have two questions :
1 - Is there a way to keep the order of the messages in a dialog, and if
so, what are the downsides to it?
2 - The machine wasn't in a load state (only one concurrent call) and the
ACK and the RE-INVITE should go roughly through the same processing methods
and should take took the same time to be be relayed. What can be the reason
for this?
Best Regards,
Duarte Rocha

UDP does not have any guaranteed state or order...

We have dealt with this extensively, and the only way we know to fix it
is to use the async features of Kamailio to, for example, slightly delay
every reinvite, possibly informed by some state tracking/ordering of
your own in htable.

Thank you for your answer Alex.
Wheb you say you have dealt with this, do you mean this exact scenario with
re-invites and ACK or just with general packets order?
I'll look into your solution, thank you.

Yes, with reinvites appearing before, or exactly simultaneously to, the point at which the
initial invite transaction is completed and the dialogue confirmed with an e2e ACK. These
messages hit different worker threads and have somewhat unpredictable exit velocity, based
on many stochastic factors.

Hello,
if you want that all messages (requests or replies) within same dialog
(sharing the same call-id) are processed in the order of receiving, then
set the global parameter:
route_locks_size = 256
If you have more Kamailio processes, then set the value to be at least
twice the number of processes.
Cheers,
Daniel

Daniel,
Thanks! I did not know this.
I think the reason I did not know it is that this is only documented in
the devel core cookbook, and not in <= 5.2. :-)

Yes, I noticed it was not documented, I added it in master recently, but
didn't get the time to push it back being currently in a series of trips
-- not sure in which release was introduced, likely 5.2, and, if older,
I don't think before 5.1.
Hopefully there was a note about it in the wiki page with new features.
Cheers,
Daniel
