Paul, I wonder why you think the first subscribe fails with a 500 due to out of order CSeq number. Sine the second one would be sent with Cseq+1 as in first one. I don't see out of order CSeq number issue here.

In that case, you get the one notify, and the earlier subscribe fails with a 500 due to out of order CSeq number. But you get the result you wanted. > -volkan > > 2008/11/24 Evgeniy Khramtsov <[EMAIL PROTECTED]> > >> Naarumanchi Kaushik wrote: >> >>> Hi All, >>> >>> In a Subscribe dialog, can we unsubscribe before receiving 200 OK >>> for the subscribe refresh request? >>> Regards, >>> N.V.S.Kaushik. >>> >> Why not?
