1 Introducing the Cisco Unified
IP Phone Expansion Module 7915
The Cisco Unified IP Phone Expansion Module 7915 attaches
to your Cisco Unified IP Phone 7962G, Cisco Unified
IP Phone 7965G or Cisco Unified IP Phone 7975G, adding up
to 24 extra line appearances or programmable buttons to your
phone. Attaching a second Expansion Module to your
Cisco Unified IP Phone adds a total of 48 extra line appearances
or programmable buttons to your phone. See Figure 1.
Note If you are running the SCCP protocol, you can
configure a maximum of 42 lines on your phone. For
example, if you configure two 24-line Cisco Unified IP
Phone Expansion Modules on a Cisco Unified IP Phone
7962G or Cisco Unified IP Phone 7965G, you will have
a total of 54 lines (48 lines from the modules in
addition to the 6 lines on the phone). However, only the
first 42 lines will be available for use.
The programmable buttons can be configured as phone line
buttons, speed-dial buttons, phone service buttons or phone
feature buttons.

4
Additional Equipment
You also need the following equipment.
• Small flat head screwdriver—for use during the installation
• Power supply unit—depending on how many
Expansion Modules you are installing and how your
Cisco Unified IP Phone is powered, you will require power
supply unit(s) as follows:
Power over the Ethernet to
your Cisco Unified IP Phone
With one or two Expansion
Modules, you need a power
supply unit (separate
orderable item).
Power supply to your
Cisco Unified IP Phone
With one Expansion Module,
you do not need a power
supply unit.
With two Expansion
Modules, you need a power
supply unit (separate
orderable item).
Note Use of a non-Cisco certified power supply unit might
not work and voids the Cisco Unified IP Phone
Expansion Module 7915 product warranty.

Step 1 Depending on how your Cisco Unified IP Phone is
powered with one or two Expansion Modules, perform
one of the following actions to connect the power
supply:
• Your Cisco Unified IP Phone is powered over the
Ethernet with one Expansion Module:
– Connect the power supply unit to the AC
adapter port on the Expansion Module and
plug the other end into a standard electrical
power outlet in the wall.
• If your Cisco Unified IP Phone is powered over the
Ethernet with two Expansion Modules:
– Connect the power supply unit to the AC
adapter port on the Expansion Module closest
to the Cisco Unified IP Phone and plug the
other end into a standard electrical power
outlet in the wall.
• If your Cisco Unified IP Phone is powered with a
power supply unit with one Expansion Module:
– Reconnect the original Cisco Unified IP Phone
power supply unit to the AC adapter port on
the Cisco IP Phone and plug the other end into
a standard electrical power outlet in the wall.
• If your Cisco Unified IP Phone is powered with a
power supply unit with two Expansion Modules:
– Connect a second power supply unit to the AC
adapter port on the Expansion Module closest
to the Cisco Unified IP Phone and plug the
other end into a standard electrical power
outlet in the wall.
Step 2 Reconnect the Cisco Unified IP Phone handset and
network connection.

3 Features of the Cisco Unified IP
Phone Expansion Module 7915
The Cisco Unified IP Phone Expansion Module 7915 includes
the following features.
1 2
187193
1Phone screen—Displays the phone number, speed dial
number (or name or other text label), phone service,
phone feature or Privacy assigned to each button. Icons
indicating line status appear similar to, and function the
same as, those on the Cisco Unified IP Phone to which it
is attached.

17
4 Using the Cisco Unified IP Phone
Expansion Module 7915
The Expansion Module 7915 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. Most call functions, such as answering a
call, placing a call on hold, transferring a call, and so on, are
performed from the Cisco Unified IP Phone.
2Lighted Buttons—12 buttons. Each button corresponds to
one line (just like on the Cisco Unified 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 green light
• Call transfer: steady green light
3Shift Buttons—2 buttons. Each button corresponds to one
page of 12 line keys. Page one is labeled with the number
1 and page two is labeled with the number 2. The lights
beneath each button indicate the state of the page as
follows:
• Page is active: steady green light
• Page is inactive: light off
• A call is ringing on an inactive page: flashing
amber light
• A call on hold on an inactive page: flashing
amber light

18
Note If the Expansion Module 7915 buttons are configured
as phone features, they can be performed from the
Expansion Module.
Refer to the phone guide for your Cisco Unified IP Phone for
instructions about using your phone.
The following is a typical scenario when using the Cisco Unified
IP Phone and Cisco Unified IP Phone Expansion Module 7915
combination.
You receive a call for your Director at extension 12345. You
look at your Cisco Unified IP Phone Expansion Module 7915
and see that your Director has a call in progress with another
party and also has another call on hold. Looking down the
Cisco Unified IP Phone Expansion Module 7915 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.
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 Unified IP Phone for
more information.

Configuring the Buttons on Your Cisco
Unified IP Phone Expansion Module 7915
Similar to your Cisco Unified IP Phone, you can configure speed
dial numbers or program buttons to access phone services on
the Cisco Unified IP Phone Expansion Module 7915. Before
you can do this, ask your system administrator for the following
information to access your Cisco Unified Communications
Manager 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 Unified IP Phone for
more information.
Adjusting the Contrast
Similar to your Cisco Unified IP Phone, you can adjust the
contrast on the Cisco Unified IP Phone Expansion
Module 7915. Refer to the phone guide for your Cisco Unified
IP Phone for more information.
