Cisco® Unified Communications is a comprehensive IP communications system of voice, video, data, and mobility products and applications. It enables more effective, more secure, more personal communications that directly affect both sales and profitability. It brings people together by enabling a new way of communicating-where your business moves with you, security is everywhere, and information is always available...whenever and wherever it is needed. Cisco Unified Communications is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.

The Cisco Unified IP Phone 7970G fills the communication needs of executive and high-end office environments that conduct moderate telephone traffic. Dedicated voicemail, directories, settings, and services keys are provided to deliver easy access to key features. Illuminated mute and speakerphone keys are provided to give a clear indication of speaker status. A high-resolution, color, touch-sensitive screen provides clear visual indication of the calls that are being handled, and Extensible Markup Language (XML) services deliver a rich user experience. The Cisco Unified IP Phone 7970G offers numerous important security features plus the choice of IEEE 802.3af Power over Ethernet (PoE), or local power through an optional power adaptor while still retaining compatibility with Cisco PoE equipment (Figure 1).

The Cisco Unified IP Phone 7970G is designed to grow with your organization. A dynamic, soft-key driven feature set enables the phone to keep pace with your requirements via regular software upgrades. Moves, adds, and changes are easy: users can simply pick up their phones and move to a new location anywhere on the network. The Cisco Unified IP Phone 7970G also provides accessibility features to those with special needs. Tables 1-7 present the features, specifications, and compliance information of the Cisco Unified IP Phone 7970G, Table 8 provides ordering information, and Table 9 lists available optional accessories.

Table 1. Features of Cisco Unified IP Phone 7970G




The phone offers direct access to voicemail with a single button touch.


The phone identifies incoming messages and categorizes them on the screen, allowing users to quickly and effectively return calls using direct dial-back capability. The corporate directory integrates with the Lightweight Directory Access Protocol Version 3 (LDAP3) standard directory.


The Settings feature key allows the user to adjust display contrast, select background images (if available), and select from a large number of unique ringer sounds through the User Preference menu. Network Configuration preferences also can be set up (usually by the system administrator). Configuration can be either automatically or manually set up for Dynamic Host Control Protocol (DHCP), Trivial File Transfer Protocol (TFTP), Cisco Unified CallManager, and backup Cisco Unified CallManager instances. Other available Settings submenus include Device Configuration and Security Configuration.


The Cisco Unified IP Phone 7970G allows users to quickly access diverse information such as weather, stocks, quote of the day, or any Web-based information using XML to provide a portal to an ever-growing world of applications, features, and information.


The online Help feature gives users information about the phone keys, buttons, and features. The pixel display allows for greater flexibility of features and significantly expands the information viewed when using features such as Services, Information, Messages, and Directory. For example, the Directory button can show local- and server-based directory information.


The phone has a large, high-resolution, graphical 12-bit color, touch-sensitive display, with backlighting to enhance its visual appearance (320 x 234 pixels).

Speakerphone, Mute, and Headset buttons

The phone offers high-quality speakerphone technology, including easy-to-use speaker On/Off, Microphone, Mute, and Headset buttons. These buttons are lit when active. For added security, the audible dual-tone multifrequency (DTMF) tones are masked when the speakerphone mode is used.

Ethernet switch

The internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100BASE-T Ethernet network through an RJ-45 interface with single LAN connectivity for both the phone and a colocated PC. The system administrator can designate separate VLANs (802.1Q) for the PC and Cisco Unified IP phones, providing improved security and reliability of voice and data traffic.

Headset port

A dedicated headset port eliminates the need for a separate amplifier when using a headset. This feature allows the handset to remain in its cradle, making headset use simpler.

External speaker and microphone ports

3.5-mm stereo jacks are fitted to the phone for external speakers and an external microphone. The electrical and audio characteristics are similar to those fitted to many modern PCs. However, when connecting externally powered audio equipment to these ports, the phone has no control over electrical signals that may be introduced by this external equipment. For this reason, Cisco can not endorse any external audio equipment that is connected to the phone when it is powered through inline PoE.

Volume Control

The convenient Volume Control button on the phone provides for 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 such as Walker Equipment W-10 and CE-100 amplifiers.

Adjustable foot-stand

The phone foot-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. Two optional wall-mount brackets are also offered, as noted later in this document.

Flexible power options

The Cisco Unified IP Phone 7970G supports IEEE PoE (Class III). In addition, the phone supports Cisco Prestandard Power over Ethernet (PoE), allowing power to be drawn from any of the Cisco Inline Power-capable blades and boxes. When connected to a Cisco PoE device, the phone will use Cisco Discovery Protocol (CDP) to negotiate the power available. The phone can also be powered locally with a power supply (CP-PWR-CUBE-3).

Multiple ring tones

More than 24 user-adjustable ring tones are available.

Americans with Disabilities Act (ADA) features

A HAC handset (meeting ADA requirements) is available, as well as HAC compliance for magnetic coupling to approved HAC hearing aids. The dial pad is also ADA-compliant.

Signaling protocol support

The phone is supported with Cisco Unified CallManager 3.3 or later, and Cisco Unified CallManager Express 3.2(1) and later. Both SCCP and SIP signaling protocols are supported by the phone when used with a Cisco Call Control agent.

Codec support

G.711µ and G.729a audio compression codecs are available.

Quality of service (QoS) options

The phone supports differentiated services code point (DSCP) and 802.1q/p standards.


The phone supports manufacturing-installed digital certificates, device authentication, and encryption. 802.1X link layer authentication is also provided, requires 8.2(1) or later phone firmware.

Language support

Support for more than 20 languages is built in (depends on Cisco Unified CallManager software version).

Configuration options

IP address assignment can be statically configured or configured through the DHCP client.

Voice quality

Comfort-noise generation and voice activity detection (VAD) programming are performed on a systems basis. RTCP streams are generated by the phone to provide voice quality metrics (requires 8.2(1) phone firmware or later).

Table 2. Security Features




Phones are shipped with factory-installed X.509v3 certificates. There is also an option of installing and removing certificates at the customer's site.

Device Authentication and signaling encryption

Transport layer security (TLS) with AES-128 encryption is offered when using Cisco Unified CallManager 4.0 or later and Cisco Unified CallManager Express Version 4.0(2) or later.

Media encryption

Secure Real-Time Transport Protocol (SRTP) with AES-128 encryption is offered when using Cisco Unified CallManager 4.0 or later and Cisco Unified CallManager Express Version 4.0(2) or later.

802.1X Link Layer Authentication

Phones running the 8.2(1) firmware load, or later, can utilize the 802.1X Link Layer Authentication protocol to connect to a Catalyst® switch implementing this security mechanism. A single downstream device, connected to the PC port, may also implement 802.1X Link Layer Authentication and the phone will pass through the EAPoL requests on a proxy basis.
