He hasn't worked for the NSA since 2001, and he didn't say they were archiving the voice data, just "recording the calls."

In March 2012
Wired magazine published "The NSA Is Building the Country's Biggest Spy Center (Watch What You Say)" talking about a vast new
NSA facility in Utah and said, "For the first time, a former NSA official has gone on the record to describe the program, codenamed Stellarwind, in detail," naming the official William Binney, a former NSA code breaker. Binney went on to say that the NSA had highly secured rooms that tap into major switches, and satellite communications at both AT&T and Verizon.
[8] The article suggested that the supposedly-dispatched Stellarwind continues as an active program. This conclusion was supported by the exposure of
Room 641A in AT&T's operations center in San Francisco in 2006.

Hardly exhaustive.
If you have anything indicating the program is far more exhaustive, I'm all eyes.
