How it works: If your talking on the phone, you’ll hear a tone (or click) alerting you of another call. You can also cancel the feature when you don’t want to be interrupted for one call, or while you’re on the Internet.
To activate Call Waiting with Cancel:
1. When you’re on the phone, if your hear a tone (or click) just depress your handset, or press the flash button.
2. You can alternate between calls, by depressing the handset, or pressing the flash button.
To cancel Call Waiting:
1. Before making the call, dial * 7 0, listen for three beeps, then dial tone.
2. Dial the number. The Call Waiting feature will be back on the line when you hang up from that call.
