This item should be discontinued. It only beeps when you answer the phone. Block died on arrival. I called the manufacturer's support. I told him it doesn't make any sounds as described in the instructions. He responded very little and said if the phone sellers don't call it means it's working. end of the conversation. Well, the calls kept coming. I called again and spoke to someone else. It was found that he actually arrived DOA. Didn't suggest sending it back just to take it to the dealer. I opened it up and checked the battery. Only 2 volts from the required 3 volts. I still spend 6 dollars on the battery. Okay, now I get the tone. The calls keep coming, it's the trash can. Maybe people will read this and save money and nerves.
