I'm guessing you really don't want a random number since a random number generator can generate duplicates. "Matching" the number to their ANI also has issues. What if my ANI is blocked? What if I spoof my ANI? What if I call from a SIP phone? I would "pre-compute" the random numbers and store them in a database. When a call arrives, I would invoke an AGI that would lock the table, read the first value with a null ANI, update the row with the caller's ANI, and unlock the table. You could do it in dialplan, but I find database access in dialplan ugly. Alternatively, you could mung UNIQUEID (<number of seconds since Epoch>.<number of channels created by this instance of Asterisk>) to appear to the caller as random and then store that and their ANI in a database. What happens if Asterisk is restarted in the middle of your campaign? -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards [email protected] Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 _______________________________________________ -- 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
