NODE 0edbe5e9Re: Modem Based Crypto Telephones
It's true, dialup modems are becoming so fast that low bit rate vocoders may well prove unnecessary for a secure phone with good voice quality. But vocoders are still handy for allowing the use of a slower modem (e.g., over impaired lines, such as those with a lot of taps :-)) and for freeing up bandwidth that you might want to use for other purposes (e.g., data).
