I have an update for the errors with duplicate key messages.

5678*0012 calls 5678*0002 and 5678*0007 is the subscriber for both.

When the call starts i see this:

After call answered Kmailio tries to update all 5678*0012 records with etag='*#-OFFLINE-#*'. 

Since there are more than 1 record for 5678*0012 then it gives the "duplicate key value violates unique constraint" errors.

But i couldnt understand why Kamailio tries to set 5678*0012 as offline in the first place? 

Both devices registered and lamp states on 5678*0007 are green when idle.

Btw if the call is long lamp states turn green again before call ends. And there is nothing left on table

kamailio=# select username, etag from presentity;

 username | etag

----------+------

(0 rows) 

Lamps should remain red until call ends, right?

Thanks
