I'm a little confused on what you are trying to do... obviously you have to tell the phone to listen either thru the phone itself or thru the headset so touching a button on the handset or the headset is mandatory. After that each unit will respond depending on which you selected i.e., you hit the headset button you can talk thru the head set, or hit the button on the handset and the mic on the handset will kick in. Can you confirm this happens as such?
