Call routing and AutoVOX
Windows Mobile 10, Redstone
Leaked screenshots of the Windows 10 Mobile Redstone suggests audio call routing based on the current configuration can be automatic and dynamic…as the handset uses logic to route your call to the headset, hands-free speaker or through the earpiece.
There is also a screen with a function based off of the proximity sensor, that will switch the earpiece speaker to the speakerphone on the handset when the device is removed from the skull.
The Redstone update for Windows mobile/portable/desktop is slotted for a Q2-Q3 release.
