These two articles state that "The worldwide move to digital, rather than
analog, phones and other equipment is making eavesdropping more difficult.
So are fax machines".  Can someone tell me why "digital" is harder for NSA?
Fax should be easier than voice, since there is in-band caller information.
(In the U.S., that information is legally required to be accurate.  I wonder
if they've ever seen pages from "Cali Cartel, Inc.")
