So I have a cordless phone at my desk. The landline/phone jack is in another room and calls are forwarded to my cordless phone. I would love to be able to use a bluetooth headset with the cordless phone. For audio only I know I can just plug in a bluetooth transmitter to the headphone jack in my cordless phone but that won't solve the issue of being able to speak back into it and the phone receiving my voice back. Please help!!!!!
