Phones local dial plan

Most if not any phone has a local dial plan, a way to filter what is entered in the keypad. They are used to speed up the dialing, placing the call when a complete number is dialed, saving the time to press the "dial" button, but most of the time, they are just annoying not letting us dial what we want. Here a small guide to setting up the correct dial plan for most phones
