[SR-Users] regEvent feature

[Stefan Ljung]

(A continuation on an old thread)

In the RFC 3680 it is described how a UE can subscribe to its own registration state(s). As soon as it's own registration state changes in any way - like a refresch registration - a NOTIFY is send to the subscribing terminal.

What made me hopeful was when I in the Overview's use case section for the module pua_reginfo read the line:

"A client could subscribe to it's own registration-status, so he would get notified as soon as his account gets administratively unregistered."

That's in line with how I would like to use it - Is it in any way possible to achieve that in the Kamailio?

>From the pua_regInfo module description:

Use cases for this might be:

Keeping different Servers in Sync regarding the location database
Get notified, when a user registers: A presence-server, which handles offline message storage for an account, would get notified, when the user comes online.
A client could subscribe to it's own registration-status, so he would get notified as soon as his account gets administratively unregistered.
...


So it's the last line  I want to deploy. Maybe Im over-interpreting "A client could subscribe to it's own registration-status"
I want to be able to simulate (As close a possible) a VoLTE clients reg events handling. Only the part between to and from the UE.
So no PUBLISH is needed - Kamailio needs to notify the UE about its registration status.

Hello,

afaik, the pua_reginfo is for publishing details of location records to another sip server node, main purpose being location replication. I don't think it is something for an end UA.

If you want publishing online/offline states for an user based on its registration state, look at pua_usrloc module.

I made a test configuration for trying the pua_regEvent module.
There were two things I want to ask about.
First - when the SUBSCRIBE to event 'reg' following a UEs registration to the Kamailio is responded with a NOTIFY - there was no body in the NOTIFY. I expected a XML body with registration status.
Second - When the UE re-registers to Kamailio - I expected a NOTIFY to be send on the existing 'reg' subscription, but nothing happened.
Or am I missing some configuration ?
Here's some of the conf script:
[..]
modparam("pua_reginfo", "publish_reginfo", 0)

Btw, with the above parameter value, the module is no longer sending PUBLISH requests, in other words, it is not informing the other peers that there is some update to location records.

Cheers,
Daniel
