Call Waiting ID

How Call Waiting ID Works:
Call Waiting ID has all the benefits of Caller ID and it also lets you identify your call waiting calls before you answer. A special tone alerts you to a waiting call and you also receive a visual display of the name and number of the person calling. The purchase of an add-on display or display telephone is necessary.

How To Use:
To use Call Waiting ID follow the instructions included with your Call Waiting ID display unit.

The "switchhook" is the button the handset pushes down when you hang up your phone. Some telephones have a Link or Flask key you can press instead.
