Expansion Module.
3 Features of the
Expansion Module 7914
The Expansion Module 7914 includes the following features.
1Phone screen—Displays the phone number, speed dial
number (or name or other text label), phone service, or
Privacy assigned to each button. Icons indicating line
status appear similar to, and function the same as, those
on the Cisco IP Phone to which it is attached.

4 Using the Expansion Module 7914
The Expansion Module 7914 functions as a line appearance or
programmable button module, allowing you to keep track of
calls in progress, calls on hold, and calls requiring transfer, or to
access phone services. All call functions, such as answering a
call, placing a call on hold, transferring a call, and so on, are
performed from the Cisco IP Phone. Refer to the phone guide
for your Cisco IP Phone for instructions about using your
phone.
Here is a typical scenario when using the Cisco IP Phone and
Expansion Module 7914 combination.
You receive a call for your Director at extension 12345. You
look at your Expansion Module 7914 and see that your
Director has a call in progress with another party and also has
another call on hold. Looking down the
Expansion Module 7914 screen, you note that another manager
in your group has just completed a call and could possibly assist
the incoming caller. You consult briefly with the incoming caller
and then transfer the call to the manager.
2Lighted Buttons—14 buttons. Each button corresponds to
one line (just like on the Cisco IP Phone). The lights
beneath each button indicate the state of the
corresponding line as follows:
Line available: light off
Line in use by you: steady green light
Line in use by someone else: steady red light
Line ringing: flashing amber light
You have a call on hold: flashing green light
Someone else has a call on hold: flashing red light
Call transfer: steady green light

18
Keeping Your Call Information Private
If Privacy is programmed for one of your buttons, you can keep
your call information private from users who share your lines.
If you see a button labeled “Privacy,” then this feature has been
enabled for you by your system administrator. You toggle
privacy on and off by pressing the Privacy button when
receiving an incoming call. In addition, with Privacy enabled,
other shared lines are blocked from joining your calls. Refer to
the phone guide for your Cisco IP Phone for more information.
Configuring the Buttons on Your
Expansion Module 7914
Similar to your Cisco IP Phone, you can configure speed dial
numbers or program buttons to access phone services on the
Expansion Module 7914. Before you can do this, ask your
system administrator for the following information to access
your Cisco IP Phone User Options web page:
•the URL
•your user name and password
After you have this information, you can configure your speed
dial numbers or program buttons to access phone services.
Phone services can include, for example, weather, stock quotes,
or corporate calendars and directories.
Refer to the phone guide for your Cisco IP Phone for more
information.
Adjusting the Contrast
Similar to your Cisco IP Phone, you can adjust the contrast on
the Expansion Module 7914. Refer to the phone guide for your
Cisco IP Phone for more information.
