Hello,
Kamailio 4.3:
I am testing Presence module with more complex scenario. I have 2 SIP
clients (presentity) with equal identities (3918) and one watcher (2025).
All my clients are Monster 0.9.25. My Kamailio Presence module is
configured with "retrieve_order=1" (presentity records are retrieve by
priority order). I have situation when wrong status is send to the watcher
(2025).
1. First all three clients registers and publish its own status. Below
is print from my MySQL database (presentity table)
mysql> select id,username,priority,expires,received_time,body from
presentity ORDER BY received_time DESC;
| id | username | priority | expires | received_time | body

2. Then first 3918 client publishes his mood >11111<. The status in
Presentity< table is refreshed under the id=84480.
NOTIFY is sent to 2025
with status with mood >11111<.

presentity ORDER BY received_time DESC;

3. After that the second 3918 client publishes his mood >22222<. The
status in >Presentity< table is refreshed under the right id=84481. NOTIFY
is sent to 2025 with status with mood >22222<.
mysql> select id,username,priority,expires,received_time,body from
presentity ORDER BY received_time DESC;

4. Then finally, the first 3918 changes his mood to "33333". The
status in >Presentity< table is refreshed under the right id=84480. BUT, to
2025 is sent NOTIFY with mood "22222". "received_time" timestamp of
status
with mood "33333" is higher than timestamp of status with mood
"22222". BUT
the "id" attribute of "presentity" table of status with mood
"33333" is
smaller. I think that statuses with equal "priority" are retrieved by
"id"
and not by "received_time"!?

The Wireshark trace is attached.
Can anyone help. Please? We have a big installation in the Gazprom's (Rusia)
network, where Kamailio is used as a Presence server only.
Thanks
