Hello Denys,

If you have some sipp scripts to reproduce the issue, creating an issue in our github about it would be probably a good idea.

Cheers,

Henning

Subject: [SR-Users] Re: [Presence] Updating route information for SIP NOTIFY when re-SUBSCRIBE

Hi there!

I conducted some tests on the new Kamailio 5.7.3 and unfortunately, the problem still exists.

Specifically, the problem lies in the fact that the data in the active_watchers table and the record_route field are only updated with initial Record-Route sets, and ignores any routing set changes for in-dialog re-subscribtions.

However, there is a commit on GitHub that should fix this issue, but looks did not:

https://github.com/kamailio/kamailio/commit/e52547956462ad53032be95ff5f2701785dfdd2a.

I can share sipp scripts for reproducing the problem, along with a set of pcap traces (sip and mysql).

Thanks in advance!

Thanks for the information Fred!

I tried to find some information in the module description...

The version is really old, but it works damn stably under high load and I can’t even raise my hand to touch the server.

Out of curiosity, since 5.1.2 is quite old…

Have you considered a supported branch (5.6, 5.7) or tried the most recent 5.1.10?

The change log for 5.1.x includes:

"presence: update record_route in database"
