Yes I was sure that the database, and the cache were both empty, well, kamailio was stopped, I deleted the database, and restarted kamailio again.
Everything works great, no more multiple registrations at all...until the ATA reboots, then all bets are off.   THen the old entry sits there, and a new one never gets added to the DB.

But just to not confuse anything, I have an ATA that changes call-id each reboot-- which is probably another issue and perhaps this "fix" does nothing for that anyways?

The Kamailio cache is always correct.   I attached an image.

The DB image shows one ATA with 2 SIP registrations (ddufresne and test2) rebooted, old entries still there, new entries never got added.
And one ATA that hasn't rebooted (ddufresne).
