Cisco CP-7912G  


As the market leader in IP telephony, Cisco continues to deliver unsurpassed end-to-end data and true voice-over-IP (VoIP) solutions, offering the most complete, stylish, and fully featured IP phone portfolio to enterprise and small to medium-size customers. Cisco IP phones provide unmatched levels of integrated business functionality and converged communications features beyond today's conventional voice systems.

Cisco IP phone products include pixel-based displays to bring productivity-enhancing applications to the phone, customization options that can be modified as needs change, and inline power support over Ethernet.

The Cisco IP Phone 7912G provides core business features and addresses the communication needs of a cubicle worker who conducts low to medium telephone traffic. The Cisco IP Phone 7912G offers four dynamic soft keys that guide a user through call features and functions. The graphic capability of the display provides a rich user experience by providing calling information and intuitive access to features. In addition, XML applications deliver impressive applications and network data to the Cisco IP Phone 7912G display.

The Cisco IP Phone 7912G supports an integrated Ethernet switch, providing LAN connectivity to a colocated PC. In addition, the Cisco IP Phone 7912G supports inline power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control, translating into greater network availability. The combination of inline power and Ethernet switch support reduces cabling needs to a single wire to the desktop.
