`Cisco Unified IP Phone 7911G
`
`
`
`The Cisco® Unified Communications system of voice and IP communications products and applications enables
`organizations to communicate more effectively—enabling them to streamline business processes, reach the right resource
`the first time and impact the top and bottom line. The Cisco Unified Communications portfolio is an integral part of the
`Cisco Business Communications Solution—an integrated solution for organizations of all sizes which also includes network
`infrastructure, security, and network management products, wireless connectivity, and a lifecycle services approach, along
`with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party
`communications applications.
`
`The Cisco Unified IP Phone 7911G fills the communication needs of cubicle, retail, classroom, or manufacturing workers or anyone who conducts
`low to moderate telephone traffic. Four dynamic soft keys guide users through core business features and functions, while a pixel-based display
`combines intuitive features, calling information, and extensible Markup Language (XML) services into a rich user experience. The Cisco Unified IP
`Phone 7911G offers numerous important security features plus the choice of IEEE 802.3af Power over Ethernet (PoE), Cisco inline power, or local
`power through an optional power adaptor (Figure 1).
