Hi



RFC 3265 mentioned that a UA accepting a subscription MUST send a
NOTIFY:

Section 3.1.6.2:

" Upon successfully accepting or refreshing a subscription, notifiers

   MUST send a NOTIFY message immediately to communicate the current

   resource state to the subscriber."



My question is what the Subscriber needs to do if he received the 200OK
response for the SUBSCRIBE,

But doesn't received any NOTIFY.



Should the subscriber re-subscribe? Or maintain a timer to delete the
subscription in his side?


What in case of the subscription was established by REFER method, in
this case the 200OK doesn't

Include an Expires field - so no refreshing mechanism is activated.



Thanks, Yariv
