Overview

The Panasonic KX-TGF850B Corded/Cordless Phone System is built around the idea that your phone should work for you, not against you. Its three-layered call blocking system is the centerpiece: automated call block pre-screens and silences known robocallers before they can ring your phone, telemarketing call block lets you reject callers after hearing their announced name, and a dedicated one-touch block button on the handset lets you add up to 1,000 numbers to a personal block list. Together, these features significantly reduce unwanted interruptions throughout the day.

Beyond call blocking, the system offers practical features for both personal and business use. The 2-way recording function captures both sides of a conversation at the press of a button, making it easy to review important details from client calls or medical appointments. The corded base unit features a large 3.4-inch tiltable LCD that clearly displays caller information, along with one-touch dial buttons for frequently called numbers. The included cordless handset offers full duplex speakerphone capability and voice-activated answering for hands-free convenience. With a 3,000-number phonebook, bilingual Talking Caller ID, and the ability to expand to 6 cordless handsets, the KX-TGF850B is a comprehensive communication hub for homes and small offices.
