Basically, flashing the line is ignored before the call supervises, and produces the secondary dialtone after supervision. Well, I was fooling around tonight, and discovered that the Sprint FON-card system doesn't return supervision until the eventual destination answeres. So, during the time when I'm entering the destination number and my FON-card number, the call hasn't yet supervised. I find this quite interesting, and it has a number of side effects. Those of you having cellular phones and a carrier who pays attention to actual supervision in determining when to charge for calls, take note. This means that you can use your FON-card from your cellular, and not pay any airtime for non-answered or busy calls.
