Personally I'd use the one script, started on bootup, which handles persistant
redials (and some sanity checking so your phone bill isn't outrageous if the
ISP's end is down).  No real need for a cronjob, you can do everything all in
the one place.  I've attached a few scripts that evolved and were rewritten in
english , it would be trivial to add some day/time checking to make sure it only
dials at the right times, otherwise it'll sleep for x seconds and keep testing
the date until conditions are safe to dial.  What exactly do you need it to do?

You can redial seconds after hanging up, no problem, it's just if the ISP's
systems are broken you may be making phone calls at the rate of 10-20/minute,
@25c/call for however long they're down.
