[OpenSER-Users] Wrong CSeq in NOTIFY after presence subscription refresh

I perform the following scenario (openser v1.2.1):

1) Send a SUBCRIBE to openser for the presence event with expires = 3600
2) The subscription is established. Openser sends a NOTIFY with PIDF
   body. The sequence number in the CSeq header is 516.
3) 1 hour later I send an in-dialog SUBSCRIBE to extend the subscription
   for another hour.
4) openser sends a NOTIFY having sequence number 516 in the CSeq header.

The sequence number of the NOTIFY should have been higher (517) as the
sequence numbers of in-dialog messages should increase.

I think this is a bug.

Regards,
Michel
