To activate Call Forwarding, press 72#
Dial the number you want to forward calls to. When the call is answered, Call Forwarding will be activated. If no one answers or the line is busy, press 72# again, redial the number and Call Forwarding will be activated.
To stop forwarding calls, press 73# on your home phone. You’ll hear two short tones followed by a dial tone. Call Forwarding is now deactivated.
