I downloaded and am trying out this program using the 14 day free trial, seems to be working fine. My question is this, why is it that after saying the person to call it makes the call, it automatically hands off to the 2 Plantronics BT Headsets that I am trying out M2500 and Voyager 510, whereas it does NOT automatically hand off to the Jabra BT800 or Motorola HS850 ??? I have to press the call button on the Jabra and the Motorola ?? God Bless.
