Directory lists everyone in the organisation who answers calls, human and
virtual, with their extension and whether they can be reached.
Three facts, not one
The two right-hand columns look like they are saying the same thing. They are
not, and knowing which is which saves a lot of guessing:
Being on a call wins over the declaration, because somebody who forgot to
come back from a break is still on the phone and sending the next caller
elsewhere would be wrong.
The reverse case is the one to remember: available and not registered means
unreachable. The person has said they are here and their handset is not
connected, so nothing can ring.
Presence for colleagues outside your own teams is shown as —. Their
registration still is. You may see who is in the organisation without
seeing what everyone in it is doing.
Calling somebody
Click to call rings your handset first, then the person you picked. It
always dials out as your own extension — not a colleague’s, whatever the
directory shows you. The call spends the organisation’s credit and presents
your caller ID, and both of those belong to you.
Your own availability is declared on your desk, not here.
This screen reads other people; it does not set anything.
