I did this by keeping state information in an external file. In my case all I
had was primary and backup. If you have lots of numbers you could just keep
an index into the list of numbers in the external file. The dial connect
scripts reads the file, increments the number, checks for rollover, then
uses that number to select the phone number to try.
