Core Technology: True Line-Powered Caller ID Operation

The defining innovation of this Cortelco telephone is its ability to power the Caller ID display entirely from the telephone line voltage. Unlike conventional Caller ID phones that require periodic battery replacement to maintain display functionality, this model operates maintenance-free for the life of the phone. The line-powered design ensures that Caller ID information is always available whenever the phone is connected to an active telephone line, eliminating the inconvenience of dim displays or lost functionality due to dead batteries.

The large, easy-to-read LCD screen presents incoming caller information, name, number, time, and date, with exceptional clarity, allowing users to screen calls effectively before answering.

Comprehensive Caller ID and 50-Call Memory

The line-powered Caller ID system stores up to 50 incoming calls in its memory log, providing a convenient record of missed and received communications for callbacks or reference. The display shows caller information even when you are on another call, thanks to full Caller ID on Call Waiting support. Compatible with both FSK and DTMF Caller ID formats, this telephone works seamlessly with virtually all telephone service providers offering Caller ID services.

The large LCD screen is angled for optimal viewing from a seated position, ensuring call information is always clearly visible.

Essential Feature Set for Daily Business Communication

Beyond its line-powered Caller ID capabilities, this telephone includes a comprehensive array of practical features for daily business operations. Users can store up to three frequently dialed numbers in one-touch memory locations and an additional ten numbers in two-touch memory for quick, efficient dialing. The hold and mute buttons feature visual indicators, confirming call status at a glance and preventing accidental interruptions.

A redial button simplifies calling back missed contacts, while a programmable flash button with selectable durations ensures compatibility with a wide range of PBX and VoIP systems. A convenient data port on the back allows for easy daisy-chaining of additional devices like fax machines or modems.

Voice clarity is the hallmark of Cortelco telephones, and this line-powered model delivers exceptional performance. The handset provides clear, natural voice transmission that ensures every conversation is understood with precision. The handset features adjustable volume control, allowing users to increase or decrease listening levels to accommodate personal preference or challenging hearing environments.

A three-position ringer volume control enables customization of incoming call alerts, from silent operation to a traditional bell-style ring that provides clear audible notification. The phone is hearing aid compatible, ensuring inclusive communication for all users.
