Oh ok.
So you're saying that the physical phone is extension 4000 for example.
When you log into 4000 with Hotdesk user 5000, and call 5000, you hear 5000's personal voicemail greeting.
If 5000 logs completely out, and now the desk phone is 4000 again, and someone calls 5000, they don't hear 5000's personal voicemail greeting. Correct?
When 5000 is logged out, and you call it, do you go immediately to the generic voicemail greeting, or do you hear ringing first?
