Answer 1

huh?  Dude,  I can't understand a thing you wrote!

Answer 2

I think I understand, and will try to answer.

When someone who is in a building (like a government building, or hospital) calls you, your caller ID will have the MAIN phone # shown.

when you call that number back you have to know exactly who called you to type in their extension.
