Voice commands are a feature of most mobile phones. All Plantronics Bluetooth headsets have the ability to initiate voice commands, but the phone must support this feature. Note that while some mobile phones have a voice command feature, they may not allow a Bluetooth headset to initiate it. Refer to your user's manual or contact your cell phone provider for specific information about your phone.
If your phone supports voice commands, you can activate it from the headset by pressing and holding the control button for about two seconds, until you hear a tone.
