Hello,
hard to say why its routing that way without knowing more details, if you are not getting
any related messages in the logs.
I would try to reproduce it in a test environment or during a time when you have low load
on the system. Then you could enable more debugging and can observe the topos module
internals better.
Cheers,
Henning

Subject: Re: [SR-Users] Re: TOPOS (5.1.[23]) breaks PRACK
Hello Henning,
Yes, I tried to figure out where the problem occurs, but I did not see it.
Our topos-settings at the moment:
modparam("topos", "db_url", DBURL)
modparam("topos", "contact_mode", 0)
modparam("topos", "dialog_expire", 10800)
modparam("topos", "branch_expire", 300)
modparam("topos", "rr_update", 1)
A-Side sends INVITE, we receive 100 and 183.
Then A-Side sends PRACK and we get OK back. Everything ok until now:
B-side sends an UPDATE:
2023/05/01 08:17:45.068664 <InterconnectPartner>:5060 ->

Hello,
did you already tried to look e.g. with sngrep on why the UPDATE is not routed correctly?
Just to sort out eventual other issues that are not caused from the module/code.

Hi List
I updated to 5.6.4, same behavior.
We have a setup like this: UAC -> kamailio registrar -> kamailio pstn gw (with
topos) -> PSTN.
The UPDATE goes not back from the PSTN to the UAC.
The PSTN GW tries to send it directly to the UAC instead of following the route back to
the registrar.
How did you solve this?
Regards

Hi together
As I understand this should be also fixed in kamailio 5.5.6?
We use also topos but it still breaks UPDATE.

Hello,
Yes, its aparently missing in the output. I checked in my local checkout, its there.
But the version rc0 was set later as the commits in question, so they should be
included.
If the error is still there, re-open the ticket 3090 and add more information there.

Hello again,
I've just tested 5.6.0~rc0+bpo11.20220506004754.1 from 56-nightly, but loose_route()
still returns false for early-dialog UPDATE... Does this build include c309122 and ceb688b
referenced in https://github.com/kamailio/kamailio/issues/3090?

Hello all,
Thanks for the feedback, Henning. There seems to have already been a ticket about this but
it's closed now: https://github.com/kamailio/kamailio/issues/2659
I'm a little confused here. It seems early-dialog UPDATE should be handled similarly
to PRACK, so I guess maybe a patch like
https://github.com/kamailio/kamailio/commit/37830f53b1f21fba5beef5d8e22913c… would
be needed.
However, Daniel has commented in this issue about the need to do record_route() in config.
To quote him: "The module requires record routing, so if the UPDATE requires to
re-enforce Record-Route, then you have to do it. [...] I was aware that only NOTIFY
requires to re-enforce Record-Route, but can be also a matter of UA implementation to want
it for other requests."
However, RR reinforcement for NOTIFY only happens (in the kamailio sample configuration
file) in route[WITHINDLG] only if loose_route() check is successful. In my case, UPDATEs
fail this test, so control goes directly to "sl_send_reply("404","Not
here");", same as the author of the aforementioned ticket. Unless Daniel meant
one needs to reinforce RR for PRACKs in order for subsequent UPDATEs to work?
Any thoughts?
BR,
George

Subject: Re: [SR-Users] TOPOS (5.1.[23]) breaks PRACK
This seems to be a topos issue regardless of backend, I tried with mariadb as storage and
UPDATE routing fails in the same way as it does with redis. I'll probably open an
issue on Github about this (early dialog UPDATE broken by topos). PRACK seems to work fine
in my case. Direction of UPDATE vs PRACK however is different, not sure if that's
important in any way.

Hello again,
I have confirmed the problem doesn't manifest without loading the topos module.
I'll see if I can also try a different topos backend this week to confirm if this is a
topos_redis issue or topos in general.

This is on kamailio 5.5.4.
I'll try with a different backend and without topos and post the result here as soon
as I find the time, just curious if anyone has stumbled on this with topos_redis before.
