I got a set of S9-HD bluetooth headset. Pairs up no problem, plays music, can hear pandora, but can't hear anything when I make a phone call. Blue tooth is indicated on the dialpad, volume is up, I've toggled the mute on the headset, but no luck. What am I missing? Suggestions. For what its worth, the headset hangs up a call, and can initiate a last dialed number? Thanks in advance for any help.
