Configure Backlight Timer Settings on a Cisco IP Phone 7800 or 8800 Series Multiplatform Phone
The Cisco IP Phone 7800 and 8800 Series Multiplatform Phones comprise a set of full-featured Voice-over-Internet Protocol (VoIP) phones that provide voice communication over an IP network. The phones provide all the features of traditional business phones, such as call forwarding, redialing, speed dialing, transferring calls, and conference calling. The Cisco IP Phone 7800 and 8800 Series Multiplatform Phones are targeted for solutions that are centered on third-party Session Initiation Protocol (SIP)-based IP Private Branch Exchange (PBX).
The Cisco IP Phone 7800 and 8800 Series Multiplatform Phones allows you to customize settings such as the phone name, wallpaper, logo, screen saver, brightness display, backlight setting, and so on. If you prefer to save energy, you may disable the backlight on each phone at a preset time. The desktop of the phone remains visible, even with the backlight off.
This article provides instructions on how to configure the backlight timer settings through the web-based utility or the Graphical User Interface (GUI) of your Cisco IP Phone 7800 or 8800 Series Multiplatform Phone.
