When is the Best Time to Choose Buy Cisco IP Phone 7800 Series? If your business is considering migration to the cloud, you’ll enjoy the investment protection and flexible deployment options available with the 7800 Series.

All models support deployment options including on-premises, Cisco Spark for cloud delivery, and hybrid configurations, and are planned for testing on select hosted third-party call control platforms.

The Cisco IP Phone 7800 Series phones are not only budget-friendly endpoints, but they can also help you save on operating costs.

They are Power over Ethernet (PoE) Class 1 rated, helping you optimize port availability in your wiring closets when deployed. In addition, the Cisco EnergyWise Power Save Plus option on the 7821, 7841, and 7861 models reduces power consumption by up to 60 percent in off-work hours.
