Note 3 no longer initiating phone calls through Bluetooth devices

[AC Question]

I used to be able to do this, but now it's not working. I've tried two Bluetooth devices (a Motorola Roadster 2 and a Kinivo BTC450) and pushing the button on either one of those will not initiate a phone call. At best it pauses the music for a moment, but doesn't turn on the screen or the voice commands on the Note 3. Sometimes it doesn't even turn off the music, so it's like it's not communicating with the phone at all. Any ideas? Seems like it would be a settings issue, since two different devices are behaving the same way, but I can't figure out what might have been changed.

Thanks!
