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.
The Cisco Unified IP Phone 7941G is a full-featured enhanced business IP phone that addresses the communication needs of the transaction worker (Figure 1). It provides two programmable backlit line/feature buttons and four interactive soft keys that guide a user through call features and functions, and audio controls for high-quality duplex speakerphone, handset, and headset. A built-in headset port and an integrated Ethernet switch are standard with the Cisco Unified IP Phone 7941G. The phone also features a best-of-class large, higher-resolution grayscale pixel-based LCD (Figure 2). The display provides features such as date and time, calling party name, calling party number, and digits dialed. The graphic capability of the display allows for the inclusion of higher value, more visibly rich Extensible Markup Language (XML) applications and double-byte languages.

The Cisco Unified IP Phone 7941G 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 Cisco.com. 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 provides many accessibility methods according to user preference. Table 1 lists features of the phone.
Table 1. Features of Cisco Unified IP Phone 7941G
The phone offers direct access to voicemail.
The phone identifies incoming messages and categorizes them for users on the screen. This feature allows 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 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 4-bit grayscale display (320 x 222).
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.
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 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.
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.
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.
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 supports Cisco Pre-standard Power over Ethernet (PoE), which allows powering from any of the Cisco Inline Power-capable blades and boxes. In addition, it supports IEEE 803.af PoE. The phone can be powered locally with a power supply (part number 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 (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.
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.
Support for more than 20 languages is built in (depends on Cisco Unified CallManager version).
IP address assignment can be statically configured or configured through the DHCP client.
Comfort-noise generation and voice activity detection (VAD) programming are performed on a system basis.
