How do I program a Payphone?

I've just purchased a payphone with a Intellicall Intellistar board inside it.. Is there any way I can reprogram this without calling the manufacturer?

Well there is a large community of Phreaking enthusiasts out there... I say enthusiasts because there aren't many Phreak's left. However, getting the info direct from the manufacturer would be best, and I encourage you to share it in turn.

This is specialized information, so if for some reason you can't contact the manufacturer, I suggest you place an advertisement for assistance in 2600: The Hacker Quarterly
