Bluetooth issues

I am using a Plantronics Voyager bluetooth headset on the RC app for android. I am unable to pick up or hang up a call using the bluetooth. My phone is not always in front of me so this is crucial for my daily use of RC. Anyone have any ideas on how to rectify this? I also have the desktop app and my headset is connected to my computer as well but I can't have my ear dinging all day with the amount of notifications I get on my comp.
