To activate Call Forwarding:

  • Lift the receiver and listen for the dial tone.
  • Dial *72 (rotary dial 1172).
  • Again, listen for the dial tone.
  • Now dial the number where you wish your calls forwarded, followed by a # sign (speed calling codes may be used if you also have this feature).
  • If someone answers at the number, call forwarding is established.
  • If the call is not answered, hang up and within 2 minutes repeat the process. Call forwarding will be activated and you will hear a confirmation tone.

Once you have activated call forwarding, the phone will ring one short time each time a call is forwarded. You can still make out-going calls from this phone without interfering with incoming calls.

To deactivate Call Forwarding:

  • Dial *73 (rotary dial 1173) and wait for the confirmation tone.

Ensure important or emergency calls can get through even when your phone is in use. Call Waiting allows you to receive a second call while you are using your phone. If someone dials your number while you are using your phone, you may do one of the following:

  • Hang up. This ends your first call. The phone will ring and when you pick it up you are connected to the second call.
  • Depress the receiver button for 1/2 second and release. Your first call is put “on hold,” and you are connected to the second caller. You can alternate between calls each time you depress and release the receiver button for 1/2 second. Each conversation is private.
  • Ignore the beep, and keep talking to your first call.


You can cancel Call Waiting for a specific call.

To cancel Call Waiting:

  • Lift the receiver for dial tone.
  • Dial *70. You’ll hear a dial tone again. Simply dial your call as you normally would.
  • Your Call Waiting will be canceled for the remainder of that one call only. Callers will hear a busy signal. When you hang up, your Call Waiting feature will be automatically reactivated.
  • If you also have three-way calling you can cancel call waiting during an ongoing call. Just depress and release the receiver button for 1/2 second to put your first call “on hold”.
  • Then dial *70. You’ll hear two beeps and be automatically reconnected to your call.

At the command of *69, your phone will dial the last caller’s number.
