Bluetooth Issues

I have used this app for a year now. The entire time being connected to an external bluetooth headset. It will no longer work with any headset. I have tried getting three different headsets, uninstalling and reinstalling, resetting my cell phone, and attempting to change the phone type while on the call from handset to bluetooth. Nothing is working. I can use the headset on my cell phone on personal calls just fine. I can hear the ringtone in my headset for GoToConnect but cannot answer the phone. Nor can I use it after answering the phone regularly. Is this something any has come across or has any other idea on how I can remedy this situation? Any help is appreciated.
