My voice dialing has been acting up. I have a Motorola H500 Bluetooth headset. It is paired correctly. WHen i hit the button on the headset to make a call, the prompt comes through the speaker on the device rather than the headset. If i do a battery pull and reset, it will work correctly one time and then reverts back to coming through the device rather than the headset on subsequent tries. Does anyone have any idea why this would be doing this?
