Speed dial allows instant access to commonly contacted numbers. It eliminates the hassle of digging out an address book to look up the number. AT&T offers two different types of speed dial for landlines. There is a speed dial listing for up to eight numbers, and one for up to thirty. Both can be set up on the same line, and which one you set up is determined by the number you dial during set up. Once speed dial is set up, you just pick up the phone and press the one or two digit number associated with the number you want to call. Writer Bio
