Cisco SIP Phone 3911

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 offers the choice of IEEE 802.3af Power over Ethernet (PoE), or local power through an optional power adaptor.
