2016 Ford F-150 with Sync3. Our cell phones connect to Sync just fine but we can not seem to make or receive calls. Today my wife called me from the truck. I answered and she could hear me but I could not hear her. Called her back she answered and same problem. It has worked intermittently a few times. Have the same issue when my cell phone is paired. I have disconnected them and reconnected. Done a master reset and nothing has fixed it.
