You can encode a phone call, typically limited to a frequency response of between, roughly, 350Hz and 3,500Hz at 192kbps. Probably 16kbps would suffice.
Or even lower, AMR (http://en.wikipedia.org/wiki/Adaptive_multi-rate_compression) sounds fairly good at its max rate of 12.2 kbps, and not too bad at 8kbps.
