Maybe, but that's not the point. Not everyone who is forced to be behind a NAT is in an enterprise environment.

You don't have a problem with it, but others do.

Oh, your right... so all the time that IM vendors invested in implementing voice chat was truly a waste, because there is absolutely NO demand for it. And all those users that currently are using voice chat as we speak/type have simply missed the fact that they could pick up the phone to pay more for their conversation. (As I finish this reply, I realize it was a waste of my time... but now that it's written, I'll send it anyway.) ~armando 0-- --0 | Armando L.
