Общение лицом к лицу становится реальностью
Важным компонентом системы унифицированных
коммуникаций Cisco Unified Communications является персональный
настольный видеотелефон Cisco Unified 7985G, который делает возможным
мгновенное общение лицом к лицу как для руководителей, так и для
обычных менеджеров компании. Эта модель объединяет все необходимые
компоненты для осуществления видеовызова - камеру, ЖК-дисплей, динамик,
кнопочную панель и трубку - в виде одного удобного в эксплуатации
устройства. Доступ к объединенным возможностям IP-телефонии и
IP-видеотелефонии предоставляется пользователям с использованием
унифицированного плана нумерации и общего каталога - в рамках единой
инфраструктуры унифицированных коммуникаций Cisco Unified
Communications - с помощью Cisco Unified CallManager.
Помимо прочего, IP-телефон Cisco Unified 7985G предлагает:
- Целый ряд функций телефонии, таких как переадресация вызова,
перевод вызова, конференц-связь и удержание вызова (теперь все эти
функции доступны в рамках видеотелефонии)
- Целый ряд методов определения доступности абонента, базирующихся на предпочтениях пользователей
- Прямой доступ к каталогам, услугам, настройкам и сообщениям голосовой почты с IP-телефона
- Специальные кнопки для работы с видеофункциями: Самопоказ (Self
View), Картинка в картинке (Picture in Picture), Отключение видео
(Video Mute), Дисплей (Display) и Яркость (Brightness)
Features
The
Cisco Unified IP Phone 7985G is a dynamic device designed to grow with
your system capabilities. Call features such as call forwarding,
transfer, conferencing, and hold are now available with video and are
all initiated through the IP phone. Using Cisco Unified Communications
Manager, IP telephony and IP video telephony are delivered to every
employee using a unified dial plan and a common directory, over a
single Cisco Unified Communications solution infrastructure.
Through
software updates to the phone flash memory, features keep pace with
changes. No manual configuration of the phone is required when the user
changes location; the user simply picks up the phone and moves to the
new location anywhere on the network. The Cisco Unified IP Phone 7985G
provides many access methods according to user preference. In addition
to the Messages, Directories, Settings, and Services buttons, the Cisco
Unified IP Phone 7985G has five buttons to control display features.
Table 1 lists the features of the Cisco Unified IP Phone 7985G.

|
Feature
|
Description
|
|
Messages button
|
The phone offers direct access to voicemail.
|
|
Directories button
|
The
phone identifies incoming messages and categorizes them on the screen,
allowing users to quickly and effectively return calls using the
direct-dial-back capability. The corporate directory integrates with
the Lightweight Directory Access Protocol Version 3 (LDAP3) standard
directory.
|
|
Settings button
|
The
Settings button allows users to adjust the display contrast, select
background images (if available), and select from a large number of
unique ring sounds through the User Preferences menu. Network
configuration preferences also can be set (usually by the system
administrator). Configuration can be either automatically or manually
set up for Dynamic Host Configuration Protocol (DHCP), Trivial File
Transfer Protocol (TFTP), Cisco Unified Communications Manager, and
backup Cisco Unified Communications Managers.
|
|
Services button
|
The
Cisco Unified IP Phone 7985G 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 applications, features, and information.
Note: Services are not currently active; users will see the message "The Key is not active" when they press the Services button.
|
|
Help
|
The online Help feature gives users information about the phone keys, buttons, and features.
|
|
Speakerphone, Mute, and Headset buttons
|
The
phone features high-quality, speakerphone technology, including an
easy-to-use speaker On/Off button, Microphone Mute button, and Headset
button. These buttons are lighted when active.
|
|
Ethernet switch
|
The
internal Cisco 2-port Ethernet switch allows 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.
|
|
Headset port
|
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, simplifying headset use.
|
|
Volume control
|
The
convenient volume control on the phone allows easy decibel-level
adjustments for the speakerphone, handset, headset, and ringer.
|
|
Self-View button
|
The
Self-View button switches the video image from incoming to outgoing
video. The Self-View button displays your outgoing picture in
full-screen mode, allowing you to see what you are transmitting.
|
|
Picture-in-Picture (PIP) button
|
The
PIP button displays a smaller picture of the outgoing video. The PIP
display appears on top of the larger incoming picture when users are on
a call, allowing them to see both pictures at the same time.
|
|
Video Mute button
|
This
button toggles the Video Mute feature on or off. When video mute is
active, the videophone does not send out the user's video image. The
far-end video phone displays a muted-video icon to indicate that the
near-end user has enabled video mute.
|
|
Display button
|
The
Display button toggles the menu on and off. With this button, all the
information displayed on the phone screen, including soft-key labels,
lines, and call information, can essentially be removed and the video
image set for full-screen view.
|
|
Brightness button
|
This button controls monitor brightness.
|
|
Flexible power options

The
Cisco Unified IP Phone 7985G can receive power down the LAN from any
Cisco IEEE 803.3af Power-over-Ethernet (PoE) switch. It also can be
powered locally with a power supply (part number CP-PWR-CUBE-3).
|
|
Multiple ring tones
|
More than five user-adjustable ring tones are available.
|
|
American Disabilities Act (ADA) features
|
A
handset that meets Hearing Aid Compatibility (HAC) Act requirements is
