Call Waiting *analog phones only

When you are busy on a call, sends a distinctive tone to notify you of another incoming call. This allows you to complete or hold your present call and pick up the waiting call. It will save you from missing calls, and your waiting caller from having to call back later.

To use, when you hear the beep indicating an incoming call, press "Flash" or hit the switchhook for a short moment. You will hear a burst of tone, followed by a dial tone. Dial 606 to connect to the second caller.
