Hi all,
A SUBS req for event 'presence' is sent to Server. Server sends a NOTIFY
with event 'reg'.
Here, the dialog id (callid, from and to tag) matches exactly, but Event is
different.
What error response has to be sent by the client for NOTIFY? 481 or 489
or xxx?
I guess, 481 means tht the dialog itself does not exist (the callid,
from tag and to tag does not match all) and the Server will clean up the
subscription. But, the client side maintains it. So, 481 shall not be sent.
489 seems to be opt.
Pl suggest.
Best Regards,
Mohammed Hanifa
