Introducing the Most Advanced Home Smart Phone System in the market. Sporting Bluetooth connectivity with USB Charging Port. This new series from Uniden now enables you to dial and receive mobile calls on the cordless handset for convenience and versatility as well as charging your Mobile Phone simultaneously. We've introduced a handy NEW feature to the XDECT 8355 series the feature is Call Block PRO, which help to minimise unwanted phone numbers. The Call Block PRO feature goes further by targeting call centre nuisance calls (i.e. Telemarketers) and will block registered numbers that share the first digits of the phone number but with a different extension number. Another is Blackout Power Failure# Protection. When a Power Failure occurs, the charged handset temporarily supplies power to the base unit. You can then make and receives calls using a handset. What makes XDECT unique and superior to other cordless phones is the diversity antenna system for optimal reception and clarity by mitigating multi path errors. The high gain antenna allows for greater range and to eliminate dropout areas in your home.
