I have a mac running High Sierra with the newest version of the 3cx phone installed. I have a Plantronics Legend bluetooth headset paired with my Mac. I have configured the audio settings in the 3cx application to use my headset. I can make calls just fine and it works great. But if I am receiving an incoming call, I don't know how to answer it. Pressing the answer button on my headset it what I would like to be able to do but pressing that button does nothing. I assume there is some other configuration, perhaps in OSX that needs to be changed in order to allow me to press the call/answer button on the headset to answer calls. Please tell me how to accomplish this if it is possible. As it stands now, i have to use the buttons in the 3CX Phone to answer and end calls. Thanks!
