Data Sheet

The Cisco® Unified Communications system of voice and IP communications products and applications enables organizations to communicate more effectively-enabling them to streamline business processes, reach the right resource the first time and impact the top and bottom line. The Cisco Unified Communications portfolio is an integral part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes which also includes network infrastructure, security, and network management products, wireless connectivity, and a lifecycle services approach, along with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.

Providing unconstrained bandwidth to desktop applications, the Cisco Unified IP Phone 7941G-GE delivers the latest technology and advancements in Gigabit Ethernet voice-over-IP (VoIP) telephony, bringing network data and applications to users quickly with its Gigabit Ethernet port for integration with a PC or desktop server (Figure 1). "Feature identical" to the Cisco Unified IP Phone 7941G, this Gigabit Ethernet enhanced business IP phone provides two programmable backlit line/feature buttons and four interactive soft keys that guide a typical transaction user through call features and functions, and audio controls for high-quality duplex speakerphone, handset, and headset. The phone features a best-of-class large, higher-resolution grayscale pixel-based LCD for easy access to communication information, timesaving applications, and feature usage (Figure 2). It also helps customers and developers deliver more innovative and productivity-enhancing Extensible Markup Language (XML) applications and can provide double-byte languages to the display.

The Cisco Unified IP Phone 7941G-GE is dynamic, and it is designed to grow with system capabilities. Features will keep pace with new changes through software updates to the phone flash memory. Firmware changes can be downloaded from Cisco Unified CallManager and No hands-on moves and changes are required with the phone-the user can simply pick up the phone and move to the new location anywhere on your network. The Cisco Unified IP Phone 7941G-GE provides many accessibility methods according to user preference. Table 1 gives features of the phone.

Table 1. Features of Cisco Unified IP Phone 7941G-GE




The phone offers direct access to voicemail.


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 7941G-GE 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, higher-resolution, graphical 4-bit grayscale display (320 x 222).

Speakerphone, Mute, and Headset Buttons

The phone offers high-quality speakerphone technology, including an easy-to-use speaker On/Off button, Microphone Mute button, and Headset button. These buttons are lit when active. For added security, the audible dual tone multi frequency (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 10/100/1000BASE-T Ethernet network through an RJ-45 interface with single LAN connectivity for both the phone and a co-located 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.

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 7941G-GE supports IEEE Power over Ethernet (PoE). It also can be powered locally with a power supply (part number CP-PWR-CUBE-3=). Note: The Cisco Unified IP Phone 7941G-GE does not support Cisco Prestandard PoE.

Multiple Ring Tones

More than 24 user-adjustable ring tones are available.

Americans with Disabilities Act (ADA) Features

An HAC handset (meets 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 offers Skinny Client Control Protocol (SCCP) support.

Codec Support

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

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

Language Support

Support for more than 20 languages is built in.

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 system basis.
