I've never ordered from thevoice, but I have converted some MP3 to gsm
and after fighting with sox parameteres I came up with this:

sox in.wav -t gsm -r 8000 -g -b -c 1 out.gsm resample -ql vol 0.6

You can adjust the volume changing the last parameter. It works good
enough for me. With the wiki examples I got mixed result, like a
changed pitch, or the same pitch but a really slow speed for some
recordings.

Best regards,
