Cisco® Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks, delivering a media-rich collaboration experience across business, government agency, and institutional workspaces. These applications use the network as the platform to enhance comparative advantage by accelerating decision time and reducing transaction time. The security, resilience, and scalability of the network enable users in any workspace to easily connect anywhere, anytime, and anyplace, using any media, device or operating system. Cisco Unified Communications is part of a comprehensive solution that includes network infrastructure, security, wireless, management applications, lifecycle services, flexible deployment and outsourced management options, and third-party applications.

The Cisco Unified SIP Phone 3911 is a cost-effective, entry-level phone that addresses the needs of a lobby, laboratory, manufacturing floor, and hallway. The capabilities of the phone can also fill the communication needs of cubicle, retail, classroom, or manufacturing workers or anyone who exhibits low to moderate telephone usage. This single-line phone has a half-duplex speakerphone and internal microphone. The Cisco Unified SIP Phone 3911 provides fixed feature keys for one-touch access to redial, transfer, conference, hold, line select, mute, speakerphone, and voicemail access features. The line select, mute, conference, Message Waiting Indicator, and speakerphone keys provide LEDs to indicate status for these features. In addition, the phone supports a 2-line x 24-character display along with two menu select keys and a two-way rocker for scrolling control. This display enables support for additional capabilities such as caller ID, call history, and the ability to configure the phone. Finally, the Cisco Unified SIP Phone 3911 (Figure 1) offers the choice of IEEE 802.3af Power over Ethernet (PoE), or local power through an optional power adaptor.
