Hi,
I have 2
questions on privacy of declined
Presence subscriptions:
==== RFC 3265/SIP-Specific Event Notification
============
Section 3.1.6.3. Authentication/Authorization of SUBSCRIBE requests
Section 3.1.6.3. Authentication/Authorization of SUBSCRIBE requests
If the notifier owner is interactively queried to
determine whether a
subscription is allowed, a "202 Accept" response is returned
immediately.
subscription is allowed, a "202 Accept" response is returned
immediately.
==============================================
Q1. If a
watcher receives 202 response to SUBSCRIBE and no more
NOTIFY
messages (except the first one), does not it mean
that subscribed-UA
has declined to authorize watcher? Is it not a
breach of privacy?
I think, had the watcher
received a 200 response, there would not have been any
way for watcher to know
that the authorization was declined.
Q2. A Presence
Server receives a SUBSCRIBE request, a 202 resp. is sent,
an imm.NOTIFY is
sent.
Now, if the
subscription authorization is declined and the notifier does
not
wish to convey that
such authorization has been declined for privacy
reasons,
what is the best way to reject and thus close the
subscription
dialog?
thanks in
advance,
