Hi,
I'm in need of making/tweak an existing Kamailio Presence setup which is giving some tough time.

BLF dialog states changes are already sent across the users. SCA is working as well.

When a User comes online then it sends SUBSCRIBE with Event: dialog and don't get notified of its subscribers state right then unless the monitored extensions make a call (BLF works)

As evident from wireshark traces, the user IP phones (Test sets: Polycoms, Yealink, CISCO, Grandstream) don't send our Event: presence rather only Event:dialog and Kamailio do not send NOTIFY out to everyone. Though yes there is an internally generated PUBLISH seen and handled properly upon registration state changes.

Jitsi has been tested and Kamailio send out these registration state change info to jitsi, somce jitsi sends Event:presence in SUBSCRIBE.

I need dialog based NOTIFY to be sent out on registration state-change.

Need pointers and help on the topic, looking forward to some feedback.

Regards,
Sammy
