Well, actually it's lot of CPU for encoding 44kHz stream. I wonder how it would scale to encode 8kHz.. We currently do a daily routine to compress all ulaw files to mp3 at night time, and it takes ~6 hours of processing on 1 CPU (no parallel processing). Regarding legal reasons, can't it be linked with lame within asterisk-addons?
