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.
