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 CallManager 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 Markup Language (XML) and future features. The
Cisco Unified IP Phone 7940G is multiprotocol-capable (SCCP, SIP, and
MGCP).
Features
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:
Messages
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).
Figure 3. Messages Key
Directories
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).

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 be
either automatic or manually set up for Dynamic Host Control Protocol
(DHCP), Trivial File Transfer Protocol (TFTP), Cisco Unified
CallManagers, 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).

Services
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
Help
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).
Figure 7. Help Key
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
footstand 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 footstand 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 multifrequency (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
• G.711 and G.729a audio compression
