The device does not need an AOR. All it needs is a SIP URI that can route the SUBSCRIBE request to the device. And, of course, the device has to be well-made enough to support dialog event subscriptions. And example of how this can work: Examine your SIP phone and determine the contact address it uses. Now make a SUBSCRIBE request to the contact address (which, of course, is not an AOR). You will receive NOTIFYs describing the dialogs that are active on your phone.
