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.
Other Cisco IP Phone 7940G features include:
- 24+ user-adjustable ring tones
- A hearing-aid-compatible handset (meets American Disabilities Act [ADA]
requirements) and HAC compliance for magnetic coupling to approved HAC hearing
aids
- G.711 and G.729a audio compression
- H.323 compatible and Microsoft NetMeeting compatibility
- An IP address assignment—DHCP client or statically configured
- Comfort noise generation and voice activity detection (VAD) programming
on a system basis
The phone also includes the following
settings:
- Display contrast
- Ring type
- Network configuration
- Call status
