KX-TG6441-T Panasonic's KX-TG6441 is a mid-range base/handset combination cordless phone. It uses DECT 6.0 to minimize interference with other wireless devices. Both the handset and base have built-in speakerphones, and the base has its own dialing pad, making it possible to call from the base even if the handset is away from it. The phone also has features like talking caller ID, talking alarm clock and battery indicator, as well as silent mode and a caller blocking list that can automatically give a busy signal to unwanted callers. There is also a built-in digital answering machine. Since the base has a speakerphone, the handset and base can be used as an intercom. The KX-TG6441 can also expand to include up to 6 total handsets, and Panasonic has several packages that include multiple handsets for this same base.
