Users often have multiple extensions on a StarSystem. Those extension could be on a single location or across multiple locations under one Customer. To easily view all your extensions create a group in StarScope 2 called "My Extensions" (or any name you choose) and add all other extensions from any location to that group. Keep it at the top of your StarScope 2 display by clicking settings/Starlets/StarScope 2 to reorder the display. When someone calls one of your other extension the display will change to indicate ringing. Use the "Operator Mode" feature to "Call Steal" / drag the call to the extension you are using to answer it.
