Intercom
Intercom, a type of phone line, combines the functionality of a traditional line and a speed dial. With an
intercom line, a user can call the intercom line of another user, which auto-answers to one-way audio
whisper. The recipient can then acknowledge the whispered call and initiate a two-way intercom call.

Configuration Checklist for Intercom
Intercom, a type of phone line, combines the functionality of a traditional line and a speed dial. With an
intercom line, a user can call the intercom line of another user, which auto-answers to one-way audio
whisper. The recipient can then acknowledge the whispered call and initiate a two-way intercom call.
Users can use an intercom line to dial any other intercom line in the intercom partition, or you can
preconfigure the line to target an intercom line outside the intercom partition.
Note
Users can use an intercom line only to dial other intercom lines.
Intercom allows a user to place a call to a predefined target. The called destination auto-answers the call
in speakerphone mode with mute activated. This sets up a one-way voice path between the initiator and
the destination, so the initiator can deliver a short message, regardless of whether the called party is busy
or idle.

Introducing Intercom
To ensure that the voice of the called party does not get sent back to the caller when the intercom call is
automatically answered, Cisco Unified Communications Manager implements whisper intercom.
Whisper intercom means that only one-way audio exists from the caller to the called party. The called
party must manually press a key to talk to the caller.
Note
An auto-answer tone indicates the beginning of the whisper state for both the sender and the recipient.
Table 28-1 shows the logical steps for configuring the Cisco Unified Communications Manager
Intercom feature in Cisco Unified Communications Manager. For more information on intercom, see the
“Introducing Intercom” section on page 28-2 and the “Related Topics” section on page 28-52.

Introducing Intercom
Intercom allows a user to place a call to a predefined target. The called destination auto-answers the call
in speakerphone mode with mute activated. This sets up a one-way voice path between the initiator and
the destination, so the initiator can deliver a short message, regardless of whether the called party is busy

To ensure that the voice of the called party does not get sent back to the caller when the intercom call is

party must manually press a key to talk to the caller.
Note
An auto-answer tone indicates the beginning of the whisper state for both the sender and the recipient.
Intercom Directory Numbers and Default Devices
Each intercom line needs a default device. The intercom feature requires configuration of the Default
Activated Device field in the Intercom Directory Number Configuration window to make an intercom
line display as active. The intercom line displays only on the designated default device.
When the administrator assigns an intercom line to a device, the system sets the device as the default
device for the intercom line if not set previously. The administrator can modify the default device for the
intercom line. When the administrator changes the default device to a different device, the intercom line
gets removed from the original device, even though the intercom line may still be assigned to the original
device.
You can assign an intercom line to a device profile. Only when a user uses a device profile to log in to
the default device that matches the default device of the intercom line does the intercom line become
available. Otherwise, no intercom line displays when the user logs in.
See the “Intercom Directory Number Configuration” section on page 28-28 for configuration details.
Note
If an intercom line has been configured and assigned to a phone but fails to display on the phone, check
that the Default Activated Device value is set to this device for this intercom line. If that configuration
has taken place, check that the phone has been reset.
Intercom Directory Numbers and Cisco Extension Mobility
Be aware that intercom directory numbers (lines) are restricted to one device per intercom line. Because
Cisco Extension Mobility is widely used, mobile users need the intercom feature but need it to be
available only on a single device. You can assign intercom lines to either a regular device or to an
extension mobility profile, but the system needs to enforce that an intercom line gets associated to either
a regular device or to an extension mobility profile.
Because an extension mobility profile can be used on more than one phone simultaneously, use the
Default Activated Device field to specify which device can display this intercom line. Intercom lines that
are not used for extension mobility also require configuration of the Default Activated Device field.
The “Intercom” section of the “Cisco Extension Mobility” chapter provides additional details about
upgrading from Release 6.0(1) of Cisco Unified Communications Manager to Release 6.1(1) or later.

For additional information about the Cisco Unified Reporting application, see the Cisco Unified
Reporting Administration Guide, which you can find at this URL:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html.
Call and Line States
Intercom introduces a new call state for the intercom line, Whisper. Intercom also uses the existing Idle,
Connected, Offhook, and Digits After First line states.
Because only one intercom call can occur at a time, the intercom call state maps directly to the line state,
and call sort rules will remain unaffected.

Bulk Administration Tool
The Cisco Unified Communications Manager administrator can use the Bulk Administration Tool (BAT)
to add many intercom users at once instead of adding users individually. See the Cisco Unified
Communications Manager Bulk Administration Guide for more information.
Barge
When the intercom destination is a barge target, the Cisco Unified IP Phone can still support whisper
intercom.
When the destination caller opts to talk to the intercom caller by pressing the intercom button, the
original call has been put on hold, and the barge initiator will get released.
Do Not Disturb (DND)
The intercom call will override DND on the destination phone.
Call Preservation
When a call is preserved, the end user needs to hang up before the phone can reregister with Cisco
Unified Communications Manager. When the intercom call is in whisper mode, it represents a one-way
medium, and the terminating side might have no user at all; therefore, only the intercom call in talkback
mode will get preserved. (Whisper intercom will not get preserved.)
Cisco Unified Survivable Remote Site Telephony (SRST)
When Cisco Unified IP Phones register with SRST, the phones do not register intercom lines; therefore,
the intercom feature will not be available when the phones are registered with SRST.
Cisco Unified Communications Manager Assistant
See the Cisco Unified Communications Manager Assistant Configuration Wizard chapter in the Cisco
Unified Communications Manager Administration Guide.
CTI
You can use CTI/JTAPI/TSP to set or modify the preconfigured target directory number for an intercom
line. You will receive notification if the target directory number is updated or reconfigured through Cisco
Unified Communications Manager Administration.
Be aware that CTI/JTAPI/TSP is backward compatible if the intercom line is not configured to be
controlled by the application. If the intercom line is configured in the application user list, you may have
to make changes and test the compatibility.

Cisco Extension Mobility
The intercom feature interacts with Cisco Extension Mobility. The system presents an intercom line to
a user who uses Cisco Extension Mobility to log in to a phone that supports the intercom feature if the
device profile that the user uses to log in has an intercom line that is provisioned. The phone must be the
default device for that intercom line.
See the “Intercom Directory Number Configuration” section on page 28-28 and to the “Cisco Extension
Mobility” section on page 9-1 for configuration details.
Internet Protocol Version 6 (IPv6)
Intercom can support phones with an IP Addressing Mode of IPv4 Only or IPv4 and IPv6. During an
intercom call, the talkback mode establishes media streams with the same IP version as the media stream
that is used when the caller initiates intercom. For more information on IPv6, see the “Internet Protocol
Version 6 (IPv6)” section on page 29-1.
Restrictions
The following restrictions apply to the Intercom feature:
•
Intercom calls do not follow a coverage path.
•
Hold—The system does not allow intercom calls to be placed on hold.
•
Call Forwarding—Intercom calls cannot be forwarded.
•
Transfer—The system does not allow an intercom call to be transferred.
•
iDivert—The system does not allow an intercom call to be diverted.
•
Call Pickup/Directed Call Pickup—The call pickup groups do not include intercom calls.
•
DND—Intercom overrides Do Not Disturb (DND).
•
If sufficient bandwidth does not exist, the intercom call fails.
•
If two intercom calls are directed to a target, the first one goes through; the second fails with a busy
tone.
•
Barge and cBarge—Intercom does not work with Barge and cBarge.
•
Conferencing—The system does not allow intercom calls to be conferenced.
•
When an active call is being monitored or recorded, the user cannot receive nor place intercom calls
•
Video is not supported with intercom.
Installing and Activating Intercom
Because intercom comes standard with Cisco Unified Communications Manager Release 6.0 and later,
it automatically gets installed and activated.

Configuring Intercom
Configuring Intercom
To use the intercom feature, both the caller and called phones require a dedicated intercom line button.
This line will have its own Directory Number (DN), which is its intercom code, and partition (intercom
group). The Calling Search Space for this intercom line gets used to restrict the access of intercom
destination from this phone.
Note
To guarantee that no accidental use of the intercom feature occurs by an unauthorized phone, users
cannot access intercom partition and intercom calling search space from other administrative windows,
except under the intercom feature.
Note
The system does not allow an intercom line to be shared on multiple devices. It should not have any other
feature-related configuration, such as forward, pickup, voice mail profile, and so on.

Because you might have several intercom calling search spaces in your network, Cisco Unified
Communications Manager lets you locate specific intercom calling search spaces by using specific
criteria as the basis. Use the following procedure to locate intercom calling search spaces.
Note
During your work in a browser session, Cisco Unified Communications Manager Administration retains
your intercom calling search space search preferences. If you navigate to other menu items and return to

Intercom Calling Search Space Configuration Settings
An intercom calling search space comprises an ordered list of intercom route partitions that are typically
assigned to devices. Intercom calling search spaces determine the partitions that calling devices search
when they are attempting to complete a call.
For more detailed information on calling search spaces and partitions, see “Partitions and Calling Search
Spaces” in the Cisco Unified Communications Manager System Guide.
Table 28-6 describes the intercom calling search space configuration settings. For a list of related

Configuring an Intercom Directory Number
Follow these instructions to add or update an intercom directory number (DN). You can configure the
call forward, call pickup, and MLPP phone features while you are adding the directory number.
Tip
You can assign patterns to intercom directory numbers; for example, 352XX. To avoid user confusion
when you assign a pattern to an intercom directory number, add text or digits to the intercom DN
configuration fields, Line Text Label, Display (Internal Caller ID), and External Phone Number Mask.
(These fields display for an intercom directory number only after you add the intercom directory number
and you associate the intercom directory number with a phone.)
For example, add the user name to the line text label and internal caller ID, but add the outside line
number to the external number mask, so, when the calling information displays, it says John Chan, not
352XX.
Procedure
Step 1
Choose Call Routing > Intercom > Intercom Directory Number.
The Find and List Intercom Directory Numbers window displays.
Step 2
To locate a specific intercom directory number, enter search criteria and click Find.
A list of intercom directory numbers that match the search criteria displays.
Step 3
Perform one of the followings tasks:
•
To add an intercom directory number, click the Add New button to add a new intercom directory
number. The Intercom Directory Number Configuration window displays.

Alerting Name
Enter a name that you want to display on the phone of the caller.
This setting, which supports the Identification Services for the QSIG
protocol, applies to shared and nonshared directory numbers. If you
configure an alerting name for a directory number with shared-line
appearances, when the phone rings at the terminating PINX, the system
performs the following tasks:
•
Forwards the name of the caller that is assigned to the directory
number.
•
Applies the Connected Name Restrictions (CONR) that are
configured for the translation pattern (if restrictions exist); the
originating PINX may modify the CONR, depending on the route
pattern configuration.
If you do not configure an alerting name, “Name Not Available” may
display on the caller phone. If you do not enter a name for the Display
(Internal Caller ID) field, the information in the Alerting Name field
displays in the Display (Internal Caller ID) field.
Setting the Always Display Original Dialed Number service parameter
to True impacts the alerting name functionality. If you set the service
parameter to True, the alerting name does not display on the calling
phone; only the original dialed number displays.

Calling Search Space
From the drop-down list box, choose the appropriate intercom calling
search space. An intercom calling search space comprises a collection
of intercom partitions that are searched for numbers that are called from
this intercom directory number. The value that you choose applies to all
devices that are using this intercom directory number. For configuration
information about calling search space for directory numbers, see the
“Calling Search Space” section on page 28-36.
Changes result in an update of the numbers that the Call Pickup Group
field lists.
You can configure calling search space for forward all, forward busy,
forward no answer, forward no coverage, and forward on CTI failure
directory numbers. The value that you choose applies to all devices that
are using this directory number.
You must configure either primary forward all calling search space or
secondary forward all calling search space or both for call forward all to
work properly. The system uses these concatenated fields (Primary CFA
CSS + Secondary CFA CSS) to validate the CFA destination and forward
the call to the CFA destination.
Note
If the system is using partitions and calling search spaces, Cisco
recommends that you configure the other call forward calling
search spaces as well. When a call is forwarded or redirected to
the call forward destination, the configured call forward calling
search space gets used to forward the call. If the forward calling
search space is None, the forward operation may fail if the
system is using partitions and calling search spaces. For
example, if you configure the forward busy destination, you
should also configure the forward busy calling search space. If
you do not configure the forward busy calling search space and
the forward busy destination is in a partition, the forward
operation may fail.
When you forward calls by using the CFwdAll softkey on the phone, the
automatic combination of the line CSS and device CSS does not get
used. Only the configured Primary CFA CSS and Secondary CFA CSS
get used. If both of these fields are None, the combination results in two
null partitions, which may cause the operation to fail.
If you want to restrict users from forwarding calls on their phones, you
must choose a restrictive calling search space from the Forward All
Calling Search Space field.
For more information, see “Partitions and Calling Search Spaces” in the
Cisco Unified Communications Manager System Guide.

The following sections explain, through written word and the use of illustrations, how to use intercom.
•
Case Studies, page 28-38
•
Illustrated Explanation of Intercom, page 28-39
Case Studies
The following information explains how intercom works when it is initiated to an idle phone and to a
busy phone.
Intercom to an Idle Phone
When Alice intercoms Bob, Bob will receive an intercom tone first, followed by the voice of Alice.
Alice, however, will not hear Bob.
If Bob has his headset on, he will use it to hear Alice; otherwise, the speaker will get used.
Intercom to a Busy Phone
Bob and Carol are speaking when Alice places an intercom call to Bob. The voice of Alice voice will get
mixed with the voice of Carol voice to be played to Bob; however, Alice cannot hear Bob, while Carol
will continue to hear Bob.
For most cases, Carol will only hear Bob, but not Alice; however, if Bob is using speakerphone when
conversing with Carol, the voices of Alice and Bob might be mixed when they are sent to Carol.
The busy phone means that an active call exists on the phone of Bob, or it represents an outgoing call
that has not connected yet.
For intercom terminating caller to end the intercom call without talking to the originator, the caller needs
to press I-help button followed by intercom button to bring the softkey set for intercom into focus. User
then can press ‘EndCall’ softkey to end the call.
