After wiping data and installing 9.7.19 to replace global version, when running for the first time I made phone calls with nothing else connected:
* No audio through the phone's normal earpiece, but could get audio by sending to phone's speaker
* No microphone or touch tones sent to other party.
After rebooting the calling worked normally.
