Once programmed there are no special buttons to press to initiate this feature.
For example: If you live in Northern Virginia, (area code 703), and you keep forgetting to dial “1” when you are calling local calls, you can create an entry to allow you to compensate for when you forget the “1”. To do this, your entry would have an index of “703” and an entry of “1703”. Now whenever you dial 703 followed by the phone number, your YIP will dial 1703 and the phone number.
