The Cisco® IP DECT 6800 Series is a cost-effective, multi-cell, high-fidelity DECT voice communications portfolio designed to improve your organization’s person-to-person communications while reducing your operating costs on approved Unified- Communications-as-a-Service (UCaaS) platforms.

Product overview

Cisco IP DECT Phone 6800 Series Product Overview

The Cisco IP DECT Phone 6825 Handset is designed for use with the Cisco IP DECT 210 Multi-Cell Base Station. Together, these products enable the convenience of a cordless DECT on-premises mobility solution for Voice-over-IP (VoIP) service. The Cisco IP DECT Phone 6800 Series offers a mobility-enhanced handset, designed primarily for business environments that require a cordless phone to support, not just one, but multiple telephone numbers or lines. It provides a highly innovative VoIP solution for users who tend to frequently move about in their locations but must always be reachable around the premises.

With a new, intuitive, easy-to-use menu structure on the DECT 6825 Handset you can easily navigate enhanced business call-control features, including multi-call operation, and execute business-essential features such as call transfer, conferencing, hold, new call, mute, speakerphone, voicemail, intercom, and one-touch dial-out from call-history logs. Wideband audio provides unsurpassed high-definition voice quality and enhanced sound clarity while the high-resolution color screen provides clear visual information, whether it is reflecting call status, displaying stored contact information from a private or shared phonebook, or configuring handset calling features. Superior performance and range, along with highly efficient battery power usage based on Digital Enhanced Cordless Telecommunication (DECT) technology gives the Cisco IP DECT Phone 6800 Series a distinct advantage and provides an affordable solution for customers who want to deploy on-premises mobility at a lower price point.

The Cisco IP DECT 6825 Handset is ideal for any residential, home office, or business searching for an advanced, multiline cordless mobility solution with superior voice quality to boost efficiency for busy users who must be reachable, whether they are in the office or elsewhere on the premises.
