For the impatient
In order to record audio you need a special alsa state file and we provide a link to one that works below (SHA1:55888a699e969c5e2c4690e6aff47ccad7ad0f3d). It can be used to put the device into voice recording mode.
alsactl -f voip-handset.state restore arecord -D hw -f cd -v -t wav rec-$(date +%Y-%m-%d-%H-%M).wav
With these commands you'll get a file in Waveform audio format (WAV) in the local directory.
