I'm pretty sure 96,000 bits/s vastly overstates the required storage. Common VoIP codecs uses as little as 5,300 bits/s[1] and military communication systems typically only require 2,400 bits/s and can go as low as 600 bits/sec[2]. Note: this is before all the transport overhead.
And this is for live communications. Recorded voice communication can be compressed further. For example the popular G.729 VoIP codec compresses down to something like 1,000 bits/sec in archives from it's normal 8,000 bits/s required during a live call[3]. Although lower bandwidth codecs probably don't compress as much.
Please correct me if I am wrong - not an expert.

- noblethrasher 13y agoAgreed. I didn't have any reliable numbers at the time so I overestimated in favor of making it more expensive.
