The intelligent cordless phone/answering machine adds power and range to your office system. Link2Cell syncs up to two smartphones to easily make and take cell calls from handsets. A dedicated Call Block button on the base unit and handset makes it simple to register up to 250 unwanted numbers. With the 350' signal range of Class 1 Bluetooth, calls can be made and received from virtually anywhere in the office. Talking Caller ID and text ID alerts clearly announce the caller and text-sender ID information on the base unit and Link2Cell handsets. Whether someone's calling from a busy city street or from inside a raucous room, noise reduction automatically suppresses background interference while enhancing voice tones for clearer, more comfortable conversations. Powerful battery backup system keeps you connected in the event of a power outage. Other features include 3,000 number phonebook transfer, all-digital answering system and two-way speakerphone.
