This is probably a very easy question. Tho it has us stumped here. About a year ago, we setup our phones so that 3 of the 7 phones will ring. We currently have 3 lines that the main line will roll over and into if the 1st line is busy. Anyone answering 1 of the 3 phones will automatically pickup the line that is calling upon lifting the receiver. How do you set this up on in the programming section of the Norstar system? We need to have a 4th phone ringing when a call comes in.
We use M7310 as the main phone, and M7208 handsets everywhere else.
