I still think a databased* approach is the best approach. I'm sorry it's not within your current skill-set. Maybe this means you should invest some time learning the skills or hire someone who has them. If this is a toy (Guess a number...), use RAND and saydigit. If this is a contest with some sort of prize or involves anything of value, use a database. *) MySQL has a really neat generic lock facility that will come in handy.

[asterisk-users] Verification number / code
I want to distribute a random number to each of the first 100 callers to my IVR. This random number will be matched to their telephone number. Where in Asterisk can I do this? And, how? Logic. Call arrives. Context for announcement begins. You will receive a authentication code at the end of the message. Then, if they press a certain digit to confirm then I simply pass a code to them. These codes are distributed to the first 100. The 101st call does not get a code. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
