Toni, possibly that this is caused by cold solder joints on the audio management IC, or by a software incompatibility with iOS 6 or greater. Make a call to a nearby phone there should be no audio but if you press the numbers on the iPhone's keyboard, those sounds are transmitted to the other phone. Then this would be most likely an iOS problem.
