Description

Cisco Unified IP Phone 7965G

Feature Description/Benefit
Display 5-inch (12.5 cm) graphical TFT color display, 16-bit color depth, 320 x 240 effective pixel
resolution, with backlight. Allows for greater flexibility of features and applications, and
significantly expands the information viewed when using features such as Services,
Information, Messages, and Directory. Display also supports localization requiring doublebyte
Unicode encoding for fonts.
Wideband Audio Support for wideband (G.722 codec, adherence to TIA 920), including handset, headset,
and speakerphone (see Q&A for details).
Codec Support G.711a, G.711μ, G.729a, G.729ab, G.722, and iLBC audio compression codecs are
supported (see Q&A for details).
Speakerphone Full-duplex speakerphone with acoustic echo cancellation.
Messages Key Provides direct access to voicemail.
Directories Key Ready access to missed, received or placed calls (plus intercom history and directories).
Incoming messages are identified and categorized on the display, allowing users to quickly
and effectively return calls using direct dial-back capability. Corporate directory integrates
with the Lightweight Directory Access Protocol Version 3 (LDAP3) standard directory.
Settings Key Allows user to adjust display brightness, select background images (if available), and select
ringer sounds through the User Preference menu. Network Configuration preferences also
can be set up (usually by the system administrator). Configuration can be set up either
automatically or manually for Dynamic Host Control Protocol (DHCP), Trivial File Transfer
Protocol (TFTP), Cisco Unified Communications Manager, and backup Cisco Unified
Communications Manager instances. Other available Settings submenus include Device
Configuration, Security Configuration, and Model Information.
Services Key Allows users to quickly access diverse information such as weather, stocks, quote of the
day, or any Web-based information using XML.
Help Button Online Help gives users information about the phone keys, buttons, and features.
Speakerphone, Mute,
and Headset Buttons
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.
Navigation Cluster with
‘Select’ Button
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)
Display Button 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.
Ethernet Switch Internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100/1000 BASET
Ethernet network through an RJ-45 interface with single LAN connectivity for both the
phone and a co-located PC. System administrator can designate separate VLANs (802.1Q)
for the PC and phone, providing improved security and reliability of voice and data traffic.
Headset Port 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.
Volume Control Provides easy decibel-level adjustments for the speakerphone, handset, headset, and
ringer. The handset is hearing aid-compatible (HAC). Additional volume control gain can be
achieved using an inline handset amplifier.
Adjustable Foot-Stand 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.
Expansion Module Support 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.
Multiple Ring Tones 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.
Americans with Disabilities
Act (ADA) Features
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.
Quality of Service
(QoS) Options
Supports differentiated services code point (DSCP) and 802.1Q/p standards.
Security 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.
