As the market leader in true IP telephony, Cisco continues to deliver unsurpassed end-to-end data and voice-over-IP (VoIP) solutions, offering the most complete, stylish, fully featured IP phone portfolio to enterprise and small to medium-sized customers. Cisco Unified IP phones provide unmatched levels of integrated business functions and converged communications features beyond today's conventional voice systems.

The Cisco Unified IP phone products include phones with large pixel-based displays to bring productivity-enhancing applications to the phones, as well as customization options that can be modified as needs change, and provide inline power support over Ethernet. The Cisco Unified IP Phone 7940G (Figure 1) is multiprotocol-enabled to support Session Initiated Protocol (SIP), Media Gateway Control Protocol (MGCP), as well as the Cisco Unified Call Manager Skinny Client Control Protocol (SCCP).

An important offering in the IP phone portfolio, the Cisco Unified IP Phone 7940G addresses the communications needs of a transaction-type worker. It provides two programmable line and feature keys, plus a high-quality speakerphone. The Cisco Unified IP Phone 7940G also has four dynamic soft keys that guide users through call features and functions. A built-in headset port and an integrated Ethernet switch are standard with the Cisco Unified IP Phone 7940G. The phone also includes audio controls for the full-duplex speakerphone, handset, and headset. This phone also features a large, pixel-based LCD display that provides information such as date and time, calling party name, calling party number, and digits dialed. Figure 2 shows the icon buttons on the phone, with word overlay in English included in the documentation package with each phone.

The graphic capability of the display allows for the inclusion of such features as Extensible Mark up Language (XML) and future features. The Cisco Unified IP Phone 7940G is multiprotocol-capable (SCCP, SIP, and MGCP).


The Cisco Unified IP Phone 7940G is dynamic and designed to grow with system capabilities. Features will keep pace with new changes through software updates to the phone flash memory. The phone provides many accessibility methods according to user preference. Various methods or paths include buttons, soft keys, a navigation key, and direct access with the use of corresponding "ghost" digits. Each of the following features will have expanded capabilities in the future:


The Messages key offers direct access to voicemail. In the near future voicemail speech-to-text readout will be available on the display (Figure 3).

The Cisco Unified IP Phone 7940G identifies incoming messages and categorizes them for users 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 (LDAP3) standard directory (Figure 4).

Figure 4. Directories Key


The Settings feature key allows the user to adjust display contrast and select from a large number of unique ringer sounds, volume settings for all audio such as ringer, handset, headset, and speaker. Network configuration preferences can also be set up. (Network configuration is usually set up by the system administrator.) Configuration can be either automatic or manually set up for Dynamic Host Control Protocol (DHCP), Trivial File Transfer Protocol (TFTP), Cisco Unified Call Managers, and backup Cisco Unified CallManagers.
A huge advantage is the ability for no hands on moves and changes. Users can just pick up the phone and move to the new location anywhere on their network. No system administration is required (Figure 5).

The Cisco Unified IP Phone 7940G 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 features and information (Figure 6).

Figure 6. Services Key


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 (Figure 7).

The Cisco Unified IP Phone 7940G features high-quality, speakerphone technology. It also includes an easy-to-use speaker on/off button and microphone mute buttons. These buttons are lit when active (Figure 8).

The internal Cisco two-port 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 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, allowing the handset to remain in its cradle and thereby 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) and meets FCC loudness requirements for 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.
The dial pad is also ADA-compliant.
The foot stand of the Cisco Unified IP Phone 7940G 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.
The Cisco Unified IP Phone 7940G can also receive power down the LAN from any of the Cisco Inline Power-capable blades and boxes.
For added security, the audible dual tone multi frequency (DTMF) tones are masked when the speakerphone mode is used.
Other Cisco Unified IP Phone 7940G features include:

• 24+ user-adjustable ring tones

• A HAC handset (meets ADA requirements) and HAC compliance for magnetic coupling to approved HAC hearing aids
