DESC: This Connect to Cell answering system lets you make and receive landline and cellular calls. Just connect the system to your Bluetooth-enabled cellular phone to make and receive cellular calls with the ease and comfort of a home phone system. The Caller ID audibly announces the name and number of the caller on all of the handsets as well as the base unit. And the frequency band has been extended, allowing for the signal to be reproduced and tuned for a fuller and clearer sound. From Vtech. Caller ID and Call Waiting are subscribed services. Contact your local telephone company for availability, details, and costs. Use of Bluetooth Wireless Technology requires Bluetooth software and Bluetooth-compatible accessories. Additional accessories may be required.
