4.4 Self SUBSCRIBE

A self-subscription dialog involves several different SIP messages. A user sends an initial self SUBSCRIBE request illustrated in section 4.4.1. The server sends a 200 OK response illustrated in section 4.4.2. As a result of publication, the server sends a BENOTIFY message to the endpoint registered to the self-subscribing user as illustrated in section 4.4.3. Finally, the self-subscribing user can request to cancel a self-subscription as illustrated in section 4.4.4.
