Hello, I asked this a while ago, but with no success. So, let's try again... This is about callSignalAddress in URQ.
H.225v3 states in URQ 7.10.1: "callSignalAddress - This is one or more of the transport call signalling addresses for this endpoint which are to be unregistered."
So, unlike I have understood, this sentence would seem to say that I can not just unregister a single alias, but I must have "a spare" callSignalAddress to unregister as well... Does anybody else think this is not the way it should be?

IMO, the sentence means "The E.164 address, if assigned [dynamically by the GK during registration procedure], is required".
I wonder what this is doing here at all...
Action that I consider sensible at a gatekeeper: If any aliases are mentioned in URQ, just unregister those aliases; if no aliases are mentioned, unregister the user altogether (ie all aliases).
Action I consider sensible at an endpoint: Mention all aliases that are currently registered!
This may or may not tally with the way people read the spec!!!
