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