search for: user_pin_table

I need to authenticate users to make long distance calls. Basically,when the user dials a long distance dialplan pattern, I want to prompt for his pin and look it up against a table of pins:usernames in a file. If it exists, I'll use the username in the cdr accountcode and permit the call. Authenticate() looked very promising nut I couldn't get the ma options to work. Any help is
