Subject: [Sip-implementors] Declining presence info authorization and privacy

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

 

If the notifier owner is interactively queried to determine whether a
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,
