What does Respond to Caller do?

The Respond to Caller setting in the CPS allows you to control the PTT behavior whilst receiving a notification or call. If ticked, the radio follows the MOTOTRBO radios behavior of responding with a private call when the PTT is pressed. If un-ticked, when the user presses PTT, the radio goes back back to home screen and start whichever call is defined by the Personality.
