I purchased a Logitech H760 wireless headset that connects with the computer via USB. It works with, for instance, the Windows audio recorder. But, with Express Talk, I do not hear the phone calls - not even the ringing. I have options set to Logitech Wireless Headset H760. Does anyone know what I am doing wrong?

I need to leave the lines and network settngs as they are for a certain automobile manufacturer, so Expresstalk only works with their lines, etc. If I want to use Expresstalk for myself, how do I save the settings - like in a profile- or should I install a second Express Talk? Thank you
