The easiest thing for you to do is program call coverage buttons on extensions 101-104 that track the ringing of extension 100. Use button 21 for this purpose, as nobody uses it for much of anything else. This is user-level programming, which we are permitted to give here in public since it is contained within the user's guide:

At each phone you want to ring:

1. Press the speed button twice;
2. Press the button you wish to use for this feature (button 21);
3. Dial 646 + 100 and hear confirmation tone.
4. Press the on/off (speaker) button to end programming.

Each phone that you program this way will ring when ext. 100 rings and it will flash on the button you programmed as well.
