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

Hello,

I have looked through the code. I have not found the exact cause of this error. I made some modifications in sequence numbers handling in the last commit.I am not sure if they fix the problem. I will do some further analysis. Please report if you still encounter it.

Thanks,

Anca Vamanu

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.
