Dial Tones
You will encounter two different dial tones when calling with a system phone:
■Outside dial tone is generated by your local phone company to indicate that you are connected with an outside line.
■Intercom dial tone is generated by the system to indicate that you are connected with an inside line. You hear this dial tone when you are making an inside, or intercom, call.
To hear the difference between the two types of dial tones on a system phone, press a line or pool button. The dial tone you hear is an outside dial tone. To hear an intercom dial tone, press [ Intercom ].
