Online Help gives users information about the phone keys, buttons, and features.
Speakerphone includes Speaker On/Off, Microphone Mute, and Headset buttons that are lit
when active. For added security, the audible dual tone multifrequency (DTMF) tones are
masked when the speakerphone mode is used.
Four-way navigation cluster allows users to scroll vertically and horizontally. At the center of
the cluster is a 'Select' button that can be used for selection of an in-focus item (for
example, to open an underlying menu)
Indicates when phone is in power-saving sleep/inactivity mode (button is lit), and can be
used to awaken the display. Inactivity period is configured by the system administrator.
Internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000 BASE-
T Ethernet network through an RJ-45 interface with single LAN connectivity for both the
phone and a colocated PC. System administrator can designate separate VLANs (802.1Q)
for the PC and phone, providing improved security and reliability of voice and data traffic.
Dedicated headset port eliminates the need for a separate headset amplifier and allows the
handset to remain in its cradle, making headset use simpler. Both wideband (G.722) and
narrowband headsets are supported.
Provides easy decibel-level adjustments for the speakerphone, handset, headset, and
ringer. The handset is hearing aid-compatible. Additional volume control gain can be
achieved using an inline handset amplifier.
Stand is adjustable from flat to 60 degrees to provide optimum display viewing and
comfortable use of all buttons and keys. The foot-stand is keyed to match standard wall-jack
configurations for wall mounting. Optional wall-mount brackets are also offered.
An optional add-on module, the Cisco Unified IP Phone Expansion Module 7914, provides
14 additional buttons for programming directory numbers or speed dials. Up to two
expansion modules may be used.
More than 24 defined user-selectable ring tones are available. Ring tones may also be
personalized through use of the Cisco Unified Phone Application Suite.
Handset is hearing aid-compatible and meets Federal Communications Commission (FCC)
loudness requirements for the Americans with Disabilities Act (ADA). Section 508 loudness
requirements can be achieved using industry-standard inline handset amplifiers such as
Walker Equipment W-10 or CE-100 amplifiers. Dial pad is also ADA-compliant.
Supports differentiated services code point (DSCP) and 802.1Q/p standards.
Positive device identity through X.509v3 Certificates, digitally signed images,
cryptographically secure provisioning, and secure signaling and secure media with AES-
128. Cryptography is not enabled by default and may only be enabled through a
cryptographically enabled CUCM. The phone also contains an 802.1X supplicant and
supports EAPOL pass-through.
Built-in support for more than 30 languages (dependent on Cisco Unified Communications
Manager version).
IP address assignment can be statically configured or configured through the DHCP client.
