A customer has been wondering if there is a way to set his headset, a Plantronics savi 740, as the default audio device for his phone, a Cisco 7821. He has a lifter on his phone so the handset comes off of the hook automatically when he takes his headset off of the base. But, he doesn't hear dialtone from the headset until pressing the headset mode button on the phone itself. Is there anything that can be done in the phone settings to have the device recognize the headset as the audio device when the phone comes off of the hook?
