To Activate Call Forwarding:

  1. When you hear a dial tone, dial *72.
  2. When you hear a second dial tone, dial the 10 digit number you want your calls forwarded to (your temporary BT Voice phone number).
  3. Wait a few seconds to hear three short beeps or a message confirming that Call Forwarding has been activated.
  4. Hang up. You’ve successfully forwarded the phone line.
