We have a dept. head who's off on medical leave, and another person who's taking over her office while she's away, but he also has his own office. I put his extension on her phone temporarily, so he answers his line on her phone.
The display shows whoever's calling's name, but only AFTER he presses the button and answers the call. :+) I guess he's admitting he doesn't want to answer calls from certain folks. Thanks for looking, Unfundednut!
