With AT&T you used to be able to use the 7 digit number for local calls but only if you were in your home area code. So it would take a few seconds to make sure you were in your local area code, and then it would still tack on the extra 3 digit area code because the network likes 10 digit numbers, not 7. So dialing 7 digits ended up taking more time then dialing 10.
AT&T only recently started requiring the full 10 digits.
