Summarize the following:
This can usually be accomplished by picking up the receiver, or by pressing the "Call" button on your cordless telephone. You'll usually enter either *72 (Verizon or Sprint) or *21* (AT&T or T-Mobile) into the phone and then press the "Call" button, which is usually a green phone-shaped button. Call forwarding codes vary by region. If you're unsure of your phone's forwarding code, consult the manual or the website for the phone. You should hear a beep or an audio prompt to enter a phone number, at which point you can proceed. Type in the 10- or 11-digit number to which you want to forward your home phone's calls. Press the # button on your home phone to do so. On some home phones, you may have to press the "Call" button again after doing so. You should hear a beep or a chime several seconds after dialing the pound key. Once you hear the chime, you can hang up your phone; your call-forwarding service should now be active. In some cases, you may receive an automated response that confirms you have activated the call forwarding service.
Activate your phone's dial tone. Dial the call forwarding service. Listen for a dial tone. Enter your cell phone's number. Dial the pound key to complete setup. Wait for the confirmation tone.
