This phone from AT&T gives you the best in long-range coverage and clarity, due to its unique antenna and noise-filtering technology. Plus, screening calls has never been easier. With Caller ID Announce, the handset announces the name of the caller, so you don't have to scramble for the handset to see who is calling. Its full duplex handset speakerphone lets both parties speak - and be heard - at the same time, for conversations that are more true to life. And, with the DECT 6.0 digital cordless technology, your calls are protected from identity theft by being digitized and encrypted, making it nearly impossible for someone to eavesdrop on your private calls.
