1. People could make IP call without our auto-dialer on a
   conventional phone using the pre-paid IP call card.
   He/she will 1. Buy a pre-paid IP phone card 2. Scratch
   it to disclose the card number and Pin. 3. Then he/she
   finds a conventional phone 4. He/she will dial access
   number which is the ID of a carrier 5. After that, a
   voice prompt will tell him/her to input card number and
   Pin 6. When all these are finished correctly, the
   system will allow him/her to make a long distance call.
2. All the steps are really bothering and inconvenient
   because people have to do the same procedure each time
   when they make a call, and when he/she mistypes, he/she
   will have to do this again from the beginning. But with
   Auto-dialer, people just store the information of access
   number, card number, pin into memory of auto-dialer,
   then when he/she makes a call, auto-dialer will help to
   finish all the steps automatically.
