Not only is the bitrate lower, but it's also in mono, not stereo.

If a decent-quality music MP3 is 1 MB/min, then switching over to mono and cutting the sampling rate to ¼th that would give 8x the storage.

I could be wrong, but if you double it, you still get 9,000 years worth. If you quadruple it, you get 4,500 years worth.

And of course, we need to consider traditional landline and VoIP calls as well.

Still, it's a fuck of a lot of storage, so a permanent record of all phone calls in the US is not out of the realm of possibility.
