Calling (Windows Configuration Designer reference)
Use to configure settings for Calling.
These settings are intended to be used only by manufacturers, mobile operators, and solution providers when configuring devices, and are not intended for use by administrators in the enterprise.
|Setting groups||Desktop editions||Mobile editions||Surface Hub||HoloLens||IoT Core|
Enter a GEOID, select Add, and then enter the number of digits for matching caller ID.
For a list of GEOID codes and default number of digits for each country/region, see Overriding the OS default minimu number of digits for caller ID matching.
See Cause codes.
CDMA Heuristics (on by default) makes CDMA calling more user-friendly by exposing an interface that supports multiple calls with call waiting, swapping, and three-way calling.
For CDMAPriorityCallPrefix, enter a custom call prefix that would allow the user to override an ongoing call with a remote party mostly used in emergency services and law enforcement.
Set DisableCdmaHeuristics to True to disable the built-in heuristics.

Set MOSimFallbackVoicemailNumber to the voicemail number that you want to use for the phone.|
