Hi all I just wanted to make sure, that i understand this right: When an EndPoint runs into an Registration Expiration (means, if he does not reply to IRQs) then the Gatekeeper sends an URQ to the EndPoint? At least that's what i see on the Status Port. Since the EndPoint is not out there anymore, it must be the Gatekeeper sending that RRQ. Basically, it doesn't seem to make much sense to send a URQ to the EndPoint, since it is relatively sure, that the EndPoint isn't out there anymore, so it won't reply. As far as i understand H.232 an URQ is just a REQUEST, so in my Application connected to the Status Port, i may not treat an URQ as if the Endpoint isn't there - basically i should wait for an UCF. But since in this case i will never receive an UCF, i could think of an URQ to be the same as an UCF in this and only in this case. - So my first question is: What does the Gatekeeper do after he has issued the URQ on the Status Port? Does it really wait for an UCF or does it unregister the related EndPoint automatically? - My second question: Are there any other case in which the Gatekeeper will issue an URQ to the Status Port or may i be sure that each time i get an URQ on the Status Port, this means that an EndPoint actually already got unregestred? Thanks a lot for your help.
