CISCO IP PHONE 7940G
As the market leader in true IP Telephony, Cisco continues to deliver unsurpassed end-to-end data and VoIP solutions,
offering the most complete, stylish, fully featured IP Phone portfolio to enterprise and small-to-medium sized customers.
Cisco IP phones provide unmatched levels of integrated business functionality and converged communications features
beyond today’s conventional voice systems.
The Cisco IP phone family includes phones with large pixel-based displays to bring productivity enhancing applications to
the phone, as well as customization options that can be modified as needs change, and provide inline power support over
Ethernet. The Cisco IP Phone 7940G is multi-protocol enabled supporting Session Initiated Protocol (SIP), Media Gateway
Control Protocol (MGCP), as well as Cisco’s CallManager Skinny Client Control Protocol (SCCP).

The graphic capability of the display allows for the inclusion of such features as XML (Extensible Markup Language) and future features. The
7940G is multi-protocol capable (SCCP, SIP, MGCP).
FEATURES
The Cisco 7940G is dynamic and designed to grow with system capabilities. Features will keep pace with new changes via software updates to the
phone’s flash memory. The phone provides many accessibility methods according to user preference. Various methods or paths include buttons,
softkeys, a navigation key, and direct access with the use of corresponding “ghost” digits. Each of the features below will have expanded capabilities
in the future:
Messages—
Direct access to voice mail. In the near future voice mail speech to text readout on the display.

Directories—
The Cisco IP Phone 7940G identifies incoming messages and categorizes them for users on the screen. This allows 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.
Settings—
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 either be automatic or manually set up for Dynamic Host Control Protocol (DHCP), Trivial File
Transfer Protocol (TFTP), CallManager, and backup CallManagers.
A huge advantage is the ability for no hands on moves and changes. Just pick up the phone and move to the new location anywhere on your network.
No system administration is required.
Services—
The Cisco 7940G allows users to quickly access diverse information such as weather, stocks, quote of the day, or any Web-based information using
extensible markup language (XML) to provide a portal to an ever-growing world of features and information.
Help—
The online help feature gives users information about the phone's 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 Cisco 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.
The internal Cisco two-port Ethernet switch allows for a direct connection to a 10/100BASE-T Ethernet network via an RJ-45 interface with single
LAN connectivity for both the phone and a co-located PC. The system administrator can designate separate virtual LANs (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. This allows the handset to remain in its cradle, making
headset use simpler. The Cisco IP phone’s convenient volume control button 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 footstand of the Cisco 7940G is adjustable from flat to 60 degrees to provide optimum display viewing and comfortable use of all buttons and
keys. The footstand is keyed to match standard wall jack configurations for wall mounting. Two optional wall mount brackets are also offered as
noted below.
The Cisco 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 multifrequency (DTMF) tones are masked when the speakerphone mode is used.
