No, RingsBeforeAnswer does not need to be anything in particular.  Be 
aware, though, that on some lines and modems Caller*ID does not come 
until after the 1st RING.

It is invoked when the call is "answered"... thus in most cases when 
RingsBeforeAnswer is reached.

I don't understand what you mean by "initialize caller ID".

You'll want to add some debugging to it... like at the top of the script 
add:

set -x
exec 2> /tmp/dynamic-config.$$

Then you'll get shell -x debugging information in that /tmp/ file.

Thanks,
