If I record via mixmonitor(), I just get a bunch of clicks where the DTMF 
should be. I'm assuming this is because the DSP has already taken the DTMF 
out of the audio stream.

If I record via 'sudo ztmonitor 89 -R rx -T tx' and then convert to wav 
with '/usr/bin/sox -r 8000 -s -w -c 1 -t raw tx tx.wav' all I get is a 
steady 'high pitched tone' which Audacity says has peaks at 16hz, 1khz, 
2khz, 3khz and 4khz.
