Building Rollover Lines
Step 1: Set up the lines as the customer would like; usually starting with the Main number, which we will use as an example. First set up the Lines in “Line Properties” within the Phones tab. See screenshot:
As you can see it starts with 1000 and then goes on from there.
Step 2: Set up the Lines to roll over properly. For each line it will roll over to the next line, for example, Line 2 – 1000 will roll over to Line 3 – 1001 if not answered or it is busy, and so on with the other lines. See screenshot:
Step 3: Make sure the last rollover line has some place to go. It is a good idea to have it go to an Auto Attendant or Voicemail. See Screenshot:
As you can see in this screen shot above the “Call Forward Busy”, “Call Forward No Answer”, and “Call Delivery +” forwards to another number, so an Auto Attendant is usually the normal for this, or a Voicemail.
