Cisco 7912G IP Phone 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 collocated PC. In addition, the Cisco IP Phone 7912G supports inline power, which allows the phone to receive power over the LAN.
