Same issue, fixed by using ACR:
[App][Beta] ACR – Auto Call Recorder – Version 1.2.4 - xda-developers
FWIW, I took the modified version in post #938, works great on the Imagio, here's the attachment link:

I'm running Energy.IMAGIO.21679.Sense2.5.Cookie.Sep.24 with CHT2
(CHT2 absolutely
ROCKS!)
EDIT:
I set the recording to WAV @ 22kHz, play around with the settings to trade space for quality
