We have a user that is looking for the following :
When he is on phone with a client and his line is in use, he doesn't want to interrupt discussion by puting the line on hold in order to call his secretary. All he wants is to send a "beep" signal to his secretary phone, so she can come to his office. It's sending sort of emergency signal for the secretary. I was thinking about intercom, SD or other similar features but none of these will work for him.
Any ideas how I can acheive this?
