Even when the phone is on the cradle, it sometimes does not ring. When it does ring, it usually cuts out when I try to answer it. If the phone is not on the cradle when it rings, I usually have to put it on the cradle before I can answer it. We have 3 handsets, and 3 cradles, and all phones seem to have this problem. They have never worked properly, but now it's worse than ever, what can I do?! Hope someone can help!! Thanks.
