What if the card isn from AT&T or Bell Canada?
A lot of weird long distance companies came out of the woodwork up here in Canada, and many of them have bizarre calling card setups. To create a card setup for your long distance company, first figure out what you’d have to do to dial the number normally (like dial an (800) number or something, followed by a user code, followed by the number, or whatever) including the length of time between blocks of numbers. Then in the Calling Card requester from the last section, hit “New…”. Give this new card a name. Now you’ll get three text fields to insert your dialing rules. Right-click on one of them and hit “What’s this…” to get a list of commands you can insert into these boxes.
