Product description
Cisco is bringing a new standard to desk phones with a portfolio built for working in modern office environments. The Desk Phone 9800 Series was designed with IT and facilities in mind to deliver 4 new phone models. Included on each phone is the newly released PhoneOS software that simplifies the user experience and compliments our video portfolios RoomOS devices to give a seamless experience from desk spaces to meeting rooms. With expanded functionality – the 9800 Series combines secure enterprise calling, meetings, desk reservations, sustainability, and emergency notifications all in one device. You don’t need to buy a dedicated device for each feature – all the features are built into each phone.
The Desk Phone 9800 Series reduces the complexity of purchasing, deploying, managing, and training. To further simplify, you can use one device for Cisco Unified Communications Manager (CUCM), Webex Calling, Broadworks, or other 3rd party cloud calling platforms. Alongside our extensive portfolio of desk devices, the 9800 series is uniquely positioned in the market to help transform the workplace by bridging the gap between hybrid work, calling, and meetings – and is the most cost-effective solution for workstations at scale.
