The Vtech 6042 cordless phone employs DECT technology. With the Vtech 6042 in hand, users will enjoy interference-free phone calls featuring crystal clear conversations. The phone system won't interfere with wireless networks and other electronic devices. With 15 minutes of recording time, the system's built-in digital answering system answers the call when you can't. Other great features include hands-free calling with the handset's built-in speakerphone, a backlit blue keypad, bilingual menu prompts (English or Spanish), a 50-name phonebook directory, and remote message retrieval from an outside line--a great feature to ensure that you always know who's calling your home. For added convenience, an audible time and date stamp is left on all recorded messages. Upgradable to include additional handsets, this system comes with two handsets and is backed by a 1-year limited manufacturer's warranty.
