Amazon.com Product Description
Panasonic's KX-TG5210M utilizes 5.8 GHz DSS signal operation for increased call security and range and less interference. Call waiting/caller ID-ready, the phone offers a 50-call memory and dialer, accessible through the handset's three-line backlit LCD. And, it's expandable, accommodating up to three additional handsets (for a total of four). The built-in answering system features all-digital operation, meaning no moving parts and no tapes to wear out.

You can pre-program frequently called numbers, even chain dialing for automated systems that require a series of numeric inputs. The KX-TG5210M is Caller IQ compatible, a service that allows you to receive updates on weather, sports, horoscopes, and more, that are sent directly to your telephone and displayed on the handset screen (requires optional service).
