A: I need help figuring out how to use this phone.

B:Sure. First you pick up the receiver and hit one of the first 3 buttons. Do 

you hear a tone?

A: Yes, I hear the tone.

B: OK. Now you dial 9 on the keypad. Do you hear the tone change?

A: Yes, it changed.

B: Well, when you hear it change, that means you have an outside line. Where are 

you trying to call?

A: I am trying to call home.

B:OK. Well, to dial to the outside you just now dial the number. For a call 

inside the company just hit the extension number. Do you know the extensions?

A: Yes, I have a list of extensions.

B: Well, if you ever need help with an extension, you can dial O.
