This chapter provides information about the Call Display
Restrictions feature which allows you to choose the information that will
display for calling and/or connected lines, depending on the parties who are
involved in the call. By using specific configuration settings in
Cisco Unified Communications Manager Administration, you can choose to present or
restrict the display information for each call.
For example, in a hotel environment, you may want to see the
display information for calls that are made between a guest room and the front
desk; however, for calls between guest rooms, you would not want the call
information to display on either phone. The Call Display Restrictions feature
enables this functionality.

information to display on either phone. The Call Display Restrictions feature
enables this functionality.
Perform the following steps to configure Call Display
Restrictions.
Procedure
Step 1
Configure partitions for rooms, front desk, club, and the PSTN.
For more information, see topics related to partitions and the
Cisco Unified Communications Manager Administration Guide.
Step 2
Configure call park directory numbers or define a range of call
park directory numbers. Configure translation patterns for each call park
directory number for call park retrieval from rooms.
For more information, see topics related to Call Park and
the Cisco Unified Communications Manager Administration Guide
Step 3
Configure a partition for call park directory numbers to make the
partition available only to users who have the partition in their calling
search space.
For more information, see topics related to partitions and Call Park, as well as the Cisco Unified Communications Manager Administration Guide.
Step 4
Configure calling search spaces for rooms, front desk, club, the
PSTN, and room park range (for Call Park).
For more information, see topics related to calling search spaces and the Cisco Unified Communications Manager Administration Guide.
Step 5
Configure the phones for the rooms, front desk, club, and the
gateway for the PSTN.
For more information, see topics related to devices and gateways, as well as the Cisco Unified Communications Manager Administration Guide.
Step 6
Configure translation patterns and route patterns.
For more information, see topics related to translation patterns, as well as the Cisco Unified Communications Manager Administration Guide
and the Cisco Unified Communications Manager System Guide.
The Call Display Restrictions feature works within a
Cisco Unified Communications Manager cluster that is running
Cisco Unified Communications Manager 5.0 or a later version or a
Cisco Unified Communications Manager server that is running
Cisco Unified Communications Manager 6.0 or a later version. To enable Call Display
Restrictions, you must configure the following parameters:
Service Parameter:
Always Display Original Dialed Number
Translation Pattern Parameters
Name Display for Original Dialed Number When Translated
Calling Line ID Presentation
Connected Line ID Presentation
Phone Configuration/User Device Profile Parameter:
The combination of these settings allows you to determine
whether the display information for each call is allowed or restricted and how
to display the connected number.
Call Display Restrictions allow you to selectively display or restrict calling and/or connected line display information. A hotel environment, which might have the following needs, frequently requires this functionality:
For calls between a guest room and the front desk, both the room and the front desk should see the call information display of each other.
For calls between guest rooms, the rooms should not see the call information display of each other.
For calls between guest rooms and other hotel extensions (such as the club house), only the rooms should see the call information display.
For external calls from the public switched telephone network (PSTN) to the front desk or guest rooms, the call information of the caller should not display if the display settings are restricted.
For all calls to the front desk, the call information of internal calls should display.
When the front desk transfers a call from a guest room to security, the room phone shows only the dialed number for the front desk.
Call Display restrictions enablement
The basis for the functionality of the Call Display
Restrictions feature is calls being routed through different translation
patterns before the calls are extended to the actual device. Users then dial
the appropriate translation pattern numbers to achieve the display
restrictions.
Translation Pattern Configuration
To enable Call Display Restrictions, configure translation
patterns with different levels of display restrictions by choosing the
appropriate option for the calling line ID presentation and the connected line
ID presentation parameters.
Tip
You must configure partitions and calling search spaces, along with
translation patterns. For more information about these configurations, see topics related to translation pattern configuration and the
Cisco Unified Communications Manager Administration Guide.
Next, enable the
"Ignore Presentation Indicators (internal calls only)" parameter
to ignore any presentation restriction that is received for internal calls and
to ensure that the device will display the call information of the remote
party.
For users who log in to phones that are enabled for
Extension Mobility, configure this setting from the
Cisco Unified Communications Manager Administration Device Profile Configuration
window as well.
Connected Number Display
When a call routes through a translation or route pattern,
routes to a Call Forward All or Call Forward Busy destination, or gets
redirected through a call transfer or CTI application, the connected number
display updates to show the modified number or redirected number.
To turn off phone display updates so that the phone displays
only the dialed digits, set the Cisco CallManager service parameter
"Always Display Original Dialed Number" to true. When this service
parameter specifies true, the originating phone displays only the dialed digits
for the duration of the call.
You can choose if the name for the original dialed number or the number after translation is displayed using the Cisco CallManager service parameter called "Name Display for Original Dialed Number When Translated". The default setting displays the name for the original dialed number before translation. This parameter is not applicable if the "Always Display Original Dialed Number" service parameter is set to false.

Call Display restrictions examples
The following scenarios provide examples for using Call
Display Restrictions:
Front Desk calls Room-1 - Both phones display the call information
of each other.
Front Desk calls Room-1, and Front Desk transfers the call to
Room-2 - The final connected parties, Room-1 and Room-2, cannot see the call
information display of each other.
External (PSTN) calls the Front Desk - The Front Desk honors the
display settings of the external caller.
External (PSTN) calls Room-1 - Room-1 honors the presentation of
the external caller; the external caller cannot see the call information
display of Room-1.
Room-1 calls Front Desk - Both phones display the call information
of each other.
Room-1 calls Room-2 - Neither phone can see the call information
display of the other.
Room-1 calls Front Desk, and Front Desk transfers the call to
Room-2 - The final connected parties, Room-1 and Room-2, cannot see the call
information display of each other.
Room-1 calls Front Desk-1, and Front Desk-1 transfers the call to
Front Desk-2 - The final connected parties, Room-1 and Front Desk-2, can see
the call information display of each other.
Room-1 calls Room-2, and Room-2 transfers the call to Front Desk -
Room-1 and Front Desk see the call information display of each other.
Club House calls Room-1 - Club House cannot display the call
information; Room-1 can see the call information display.
All parties in a conference call - All phones see
"To Conference" for the call information display.
Room-1 calls Club House, and Club House manager has all calls
forwarded to his mobile - Room-1 sees the Club House number only.
Interactions
This section describes how the Call Display
Restrictions feature interacts with
Cisco Unified Communications Manager applications and call processing features.
The connected number display restriction applies to all calls
that originate in the system. When set to true, this setting interacts
transparently with existing
Cisco Unified Communications Manager applications, features, and call processing.
The setting applies to all calls that terminate inside or outside the system.
When the Call Display Restrictions feature is used with Call
Park, you must configure an associated translation pattern for each individual
call park number to preserve the Call Display Restrictions feature; you cannot
configure a single translation pattern to cover a range of call park numbers.
Consider the following scenario as an example:
The system administrator creates a call park range of 77x and
places it in a partition called P_ParkRange. (The phones in the guest rooms can
see the P_ParkRange partition is made visible to the phones in the guest rooms
by inclusion of it in the calling search space of the phones (CSS_FromRoom.))
The administrator configures a separate translation pattern for
each call park directory number and configures the display settings to
Restricted. (In the current scenario, the administrator creates translations
patterns for 770, 771, 772...779.)
Note
For the Call Display Restrictions feature to work correctly, the
administrator must configure separate translation patterns and not a single
translation pattern for a range of numbers (such as 77x or 77[0-9]).
Room-1 calls Room-2.
Room-2 answers the call, and Room-1 parks the call.
When Room-1 retrieves the call, Room-2 does not see Room-1 call
information display.
When you use Call Display Restrictions, you restrict the
display information for the list of participants in a conference. For more
information about conference lists, see the
Cisco Unified Communications Manager System Guide.
Conference and Voice Mail
When Call Display Restrictions are used with features such as conference and voice mail, the call information display on the phones reflects that status. For example, when the conference feature is invoked, the call information display shows "To Conference." When voice mail is accessed by choosing the "Messages" button, the call information display shows "To Voicemail."
Extension Mobility
To use Call Display Restrictions with Extension Mobility, enable the "Ignore Presentation Indicators (internal calls only)" parameter in both the Cisco Unified Communications Manager Administration Phone Configuration window and the Cisco Unified Communications Manager Administration Device Profile Configuration window.
When you enable Call Display Restrictions with Extension Mobility, the presentation or restriction of the call information depends on the line profile that is associated with the user who is logged in to the device. That is, the configuration that is entered in the user device profile (associated with the user) overrides the configuration that is entered in the phone configuration (of the phone that is enabled for Extension Mobility).
Configure Call Display restrictions
To use Call Display Restrictions, make sure that you perform
the following
Cisco Unified Communications Manager configurations:
Configure partitions and calling search spaces before you add a
translation pattern.
Configure translation patterns with different levels of display
restrictions.
From the Phone Configuration window, check the
"Ignore Presentation Restriction (internal calls only)" check
box to ensure that the call information display for internal calls is always
visible.
Configure individual, associated translation patterns for each
individual Call Park directory number, to work with the Call Park feature.
Set the
"Always Display Original Dial Number" service parameter to
True to ensure privacy and to block connected number updates for redirected
calls.
Tip
Before you configure call display restrictions, review the
task to configure Call Display restrictions.
Configure the following parameters from the
Cisco Unified Communications Manager Administration Translation Pattern
Configuration window.
Tip
For outgoing calls, the translation pattern setting at the
terminating end can override the originating
Cisco Unified Communications Manager settings.
Calling Line ID Presentation
Cisco Unified Communications Manager uses calling line
ID presentation as a supplementary service to allow or restrict the originating
caller phone number on a call-by-call basis. Choose one of the following
options to allow or restrict the display of the calling party phone number on
the called party phone display for this translation pattern:
Default - This option does
not change the calling line ID presentation.
Allowed -
Cisco Unified Communications Manager allows the display of the calling
number.
Restricted -
Cisco Unified Communications Manager blocks the display of the calling
number.
Note
If the incoming call goes through a translation pattern or route
pattern and the calling line ID presentation setting is allowed or restricted,
the system modifies the calling line presentation with the translation or route
pattern setting.
Connected Line ID Presentation
Cisco Unified Communications Manager uses connected
line ID presentation as a supplementary service to allow or restrict the called
party phone number on a per-call basis. Choose one of the following options to
allow or restrict the display of the connected party phone number on the
calling party phone display for this translation pattern:
Default - This option does
not change the connected line ID presentation.
Allowed - This option
displays the connected party phone number.
Restricted -
Cisco Unified Communications Manager blocks the display of the connected
party phone number.
Note
If the incoming call goes through a translation or route pattern and
the connected line ID presentation field is set to allowed or restricted, the
system modifies the connected line presentation indicator with the translation
or route pattern setting.
Note
If the connected number display restriction is enabled, the
connected number display does not update for modified numbers or redirected
calls.
Examples
For calls that are made
from one guest room to another, configure the calling line ID presentation and
the connected line ID presentation to restricted to ensure that the call
information does not display.
For calls that are made
from the front desk to a guest room, configure the calling line ID presentation
to allowed and the connected line ID presentation to restricted to ensure both
parties can see the call information.
Tip
For more information about calling party transformations and
connected party transformations, see the
Configure Call Display restrictions
chapter in the
Cisco Unified Communications Manager System Guide.
Configure the phone
To complete the configuration of the Call Display
Restrictions feature, check the
"Ignore Presentation Indicators (internal calls only)" check box
from the
Cisco Unified Communications Manager Administration Phone Configuration window.
For use with Extension Mobility, also configure this setting
from the
Cisco Unified Communications Manager Administration Device Profile Configuration
window.
When you set the
"Ignore Presentation Indicators (internal calls only)" field,
Cisco Unified Communications Manager always displays the remote party call information if the
other party is internal.
Cisco Unified Communications Manager does not display the remote party call information if the
other party is external and the display presentation is restricted.
Note
Ensure the calling line ID presentation and the connected line ID
presentation are configured with the
"Ignore Presentation Indicators (internal calls only)" parameter
for
Cisco Unified Communications Manager to ignore the presentation settings of
internal callers. For incoming external calls, the system maintains the
received presentation indicators even if the
"Ignore Presentation Indicators (internal calls only)" parameter
is set.
For phones that are used
at the hotel front desk, check the
"Ignore Presentation Indicators (internal calls only)" check
box, so the front desk can always see the call information display for internal
calls.
Tip
For information about phone configurations and device profile
configurations, see the
Cisco Unified Communications Manager Administration Guide.
Call Display Restrictions configuration examples
This section provides sample configurations to
enable the Call Display Restrictions feature.
From the Cisco Unified Communications Manager Administration Phone Configuration window and from the Cisco Unified Communications Manager Administration Gateway Configuration window, configure the following phones and configure the following gateway:
Configure phone A (Room-1) with partition P_Room and device/line calling search space CSS_FromRoom
{ P_Phones, CSS_FromRoom} : 221/Room-1
Configure phone B (Room-2) with partition P_Room and device/line calling search space CSS_FromRoom
{ P_Phones, CSS_FromRoom} : 222/Room-2
Configure phone C (Front Desk-1) with partition P_FrontDesk and device/line calling search space CSS_FromFrontDesk and Ignore Presentation Indicators check box enabled
Configure phone D (Front Desk-2) with partition P_FrontDesk and device/line calling search space CSS_FromFrontDesk and Ignore Presentation Indicators check box enabled
From the Cisco Unified Communications Manager Administration Call Park Number Configuration window, configure the following items for the Call Park feature:
Insert a Call Park directory number 888X
Call Park Number Range: P_ParkNumberRange/888X
Configure the translation patterns for the call park retrieval from
room: TP (11-20): 8880 to 8889
Partition: P_RoomToParkNumber
CSS: CSS_RoomParkRange
Calling Line ID Presentation and Calling Name Presentation: Restricted
Connected Line ID Presentation and Connected Name Presentation: Restricted
Call flow example
The following figure shows a graphic representation of a
sample call flow, with a description of how the Call Display Restrictions
feature works in this scenario.
Figure 1. Sample Call Flow
Room-1 calls Room-2 (directory number 222).
Room-1 has CSS_FromRoom, so Room-1 can access only phones that are
in the P_CallsFromRoomToRoom partition.
The P_CallsFromRoomToRoom partition contains 2XX, but it does not
contain directory number 222 (Room-2).
The call routes to translation pattern TP:2XX, which is configured
to restrict display information.
The TP:2XX translation pattern can access the P_Room partition
because it is configured with the CSS_Room calling search space.
The CSS_Room calling search space contains directory number 222
(Room-2).
The call connects to Room-2, but theTP:2XX translation pattern
restricts the display information.
Set the service parameter for Connected number Display Restriction
The connected number display restriction restricts the
connected line ID presentation to dialed digits only. This option addresses
customer privacy issues as well as connected number displays that are
meaningless to phone users.
Procedure
Step 1
Select System > Service
Parameters in
Cisco Unified Communications Manager Administration.
Step 2
Select the server where the
Cisco CallManager service runs, and then select the Cisco CallManager service.
Step 3
Set the Always Display Original Dialed Number service
parameter to True to enable this feature.
The default setting is False.
Step 4
(Optional)Set the Name Display for Original Dialed Number When Translated service parameter.
The default setting for the Name Display for Original Dialed Number When Translated service parameter is to display the alerting name of the original dialed number before translation. You can change this parameter to display the alerting name of the dialed number after translation. This parameter is not applicable if the Always Display Original Number service parameter is set to False.
