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 four new phone models and one Key Expansion Module (KEM). Included on each phone is the newly released PhoneOS software that simplifies the user experience and complements our video portfolio RoomOS devices to provide 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.
