Hi,

I have a simple scenario that I can't get working. There is a JAIN-SIP
application (already using 1.2.94 version, thanks for the quick fix,
Ranga) that subscribes to SipX MWI notification (SIP message flow at the
end of the message, SipX version is 3.10.2). Then it tries to
unsubscribe setting the Expires to 0. 

Please, note that in the second 202 Accepted returned by SipX, the
second To tag is missing (the dialog was set up correctly in case of the
first 202 Accepted and that the Expires in the second 202 is not 0 but a
higher number. The NOTIFY returned after the second 202 has "active"
subscription state instead of having a terminated subscription state.

What do I do wrong?

Regards,
Gabor Paller
