I am trying to use the Kamalio 4 and SIPML5 and so for it is working fine.

But when I subscribe for presentity of another then I receive all the entries of that user  in the presentity table in mysql db.

It seem that it I receive the entries that are not expired. Is there a way to get the latest status of the user or just avoid duplicate entries in the presentity table.

Please advice.

Best Regards,

Roy.
