Was that the same issue on all four devices, or different devices different problems.

And, have to ask, have you veried the speakers work? Can you play an audio file through the phone speaker and the speakerphone speaker?

I'm assuming you checked the call volume settings....correct? Again, have to ask.

Can you -- or have you -- tested yourself? What happens, for instance, if you call the cell phone from a land line number, or even from another cell phone number?


EDIT: Just saw your other thread. So, it isn't that you hear nothing. It is intermittant. Is that correct?
