[Asterisk-Users] How to do something random?

[Mike Sander]

Logically, you should build something like this:

1. Pick a number between 1 and 3
2. Save the number to a variable indicating which line you are about to try
3. Check if it's free, if so make a call
4. If not, pick a number between 1 and 2
5. Make sure you haven't tried this number before (a loop and perhaps an
array of line numbers)
6. When you find a not-yet-tried number, check if it's free. If so, make a
call
7. If not, loop again to find the remaining number, check if free, if so
make a call.
8. If you get here, all lines are busy - play the busy tone.

I'm sorry my coding is not up to scratch, but this seems like a good
application for an AGI script as it can do arrays and looping easier, and
you could build this up to many lines.
