The Bogen is for overhead speakers and horns, not the music on hold. If you google Bogen and put the part number in the search bar in their page it will tell you exactly what you have. The part you need is as big as your thumb and probably costs three bucks or less.

I have all my phones set to idle, not to pick up intercom or pick up an outside line. I find it much more convenient to press a line, dial and wait for someone to answer and IF they do, pick up the handset. I do know that I can hit a line and start dialing digits even before the dial tone goes away (yes I am the fast Bunnie) and all the digits show up in the screen and the call goes through. There may be a slight delay of a half second that you just have to live with.

Thanks, Bunnie
