Automated Dialing For Calling Cards Explained

Do you use a calling card for international long distance with your G1? Want to program in the access number and pauses so that all you have to do is press a button to dial the sequence? It isn’t hard. With most cell phones, the G1 included, a comma in the phone number field adds a one second pause. The first thing to do is gather some information before creating the new dialing sequence. You will need to know the following:

  1. The access number for the calling card (usually on the back of the card)
  2. The number of seconds before the calling card service asks for your PIN
  3. The PIN for the calling card
  4. The number of seconds before the calling card service asks for the number you are dialing
  5. The destination phone number.

Once you have the information, it is simply a matter of entering the numbers with commas between them to delay the dialing of the next numerical sequence. For example.

  1. The access number is 800 555 1212
  2. There is a 4 second delay (it is a good idea to add one or two seconds more than the actual count)
  3. The PIN is 123456
  4. There is a 3 second delay before the service asks for the destination telephone number (again, add another second or two to this count)
  5. The destination telephone number is, including your country’s international access code, 001 886 35 555 555.

Based on the above information, you would enter the following into your G1:

8005551212,,,,,123456,,,,00188635555555.

Please note the addition of an extra second to each pause sequence. This mimics the time a person might take to look up the number that follows. Some services might need to have an additional two seconds added, which would look like this:

8005551212,,,,,,123456,,,,,00188635555555.

This technique isn’t limited to calling cards. It can help automate the checking of your home or office voicemail or any other situation where you might need to navigate through voice prompts. Some people use this as a quick and easy way to reach their cellular carrier’s customer service.

Remember that voice prompts sometimes change. What you program today may need to be changed if the sequence of prompts is changed by your carrier.
