A:Answer If you are carrying the phones out of range, if the battery is weak, or if you have a lot of interference (metal plumbing, electrical, appliances, other radio waves) between the base & handset or possibly just something interfering with the phone itself since the FCC requires that household items like this must accept interference, those are the only reasons I could understand the dropped calls. (My parents actually have issues using cell phones & cordless phones in their master bathroom, for instance. It’s believed that all of the water pipes and wiring make it difficult for them to get the signal, but it doesn’t happen anywhere else inside of their home. Other than those possibilities, I’d have your telephone company check your wires OR exchange the set for the exact same set go see if you have a faulty component.
