Thanks to all. That makes it clear that UA needs to publish a status update and re register with 0 life time if it needs to "Sign Out".

If you have been publishing presence and you want to "sign out", then publish an update that expires immediately. If you have registered and you want your device to "sign out" then reregister your contact with an expires=0. You *could*, as Rakendu suggests, remove *all* registered contacts. But that would probably not be a good idea under normal circumstances. Unless you have control over all the devices that are registering they will probably reregister anyway.
