Call Display Restrictions


The Call Display Restrictions feature 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 CallManager, 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.

This chapter provides the following information about using the Call Display Restrictions feature in Cisco CallManager:

Introducing Call Display Restrictions

The Call Display Restrictions feature works within a Cisco CallManager cluster that is running Cisco CallManager 5.0. To enable Call Display Restrictions, you must configure the following parameters:

Translation Pattern Parameters

Calling Line ID Presentation

Connected Line ID Presentation

Phone Configuration/User Device Profile Parameter:

Ignore Presentation Indicators (internal calls only)

The combination of these settings allows you to determine whether the display information for each call is allowed or restricted.

This section includes the following topics:

Overview of Call Display Restrictions

Enabling Call Display Restrictions

Overview of Call Display Restrictions

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.

Enabling Call Display Restrictions

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.

See the "Configuring the Translation Pattern Parameters" section for additional information about these parameters.


Tip You must configure partitions and calling search spaces, along with translation patterns. For more information about these configurations, refer to the Translation Pattern Configuration chapter in the Cisco CallManager Administration Guide.


Phone Configuration/User Device Profile Configuration

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.

See the "Configuring the Phone Configuration" section for more information about this setting.

(For users who log in to phones that are enabled for Extension Mobility, configure this setting from the Cisco CallManager Administration User Device Profile window as well. For more information about interactions with Extension Mobility, see the "Extension Mobility" section.)

System Requirements for Call Display Restrictions

The following software components support Call Display Restrictions:

Cisco CallManager 5.0

The following Cisco SIP and SCCP IP Phones, software-based devices, and desktop applications support Call Display Restrictions:

Cisco IP Phones (Models 7902, 7905, 7910, 7911, 7912, 7920, 7940, 7941, 7960, 7961, 7970, 7971)

H.323 clients (such as Microsoft NetMeeting devices)

CTI ports (virtual devices that software-based applications use)

Cisco IP Communicator

Scenarios for Using Call Display Restrictions

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.

Interactions

The following sections describe how the Call Display Restrictions feature interacts with Cisco CallManager applications and call processing:

Call Park

Conference List

Conference and Voice Mail

Extension Mobility

Call Park

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:

1. 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.))

2. 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]).


3. Room-1 calls Room-2.

4. Room-2 answers the call, and Room-1 parks the call.

5. When Room-1 retrieves the call, Room-2 does not see Room-1's call information display.

See the "Call Park" section for additional information about using the Call Park feature.

Conference List

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, refer to the "Phone Features" section in the Cisco IP Phones chapter in the Cisco CallManager 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, you enable the "Ignore Presentation Indicators (internal calls only)" parameter in both the Cisco CallManager Administration Phone Configuration window and the Cisco CallManager Administration User Device Profile 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).

Configuring Call Display Restrictions

To use Call Display Restrictions, make sure that you perform the following Cisco CallManager configurations:

Configure partitions and calling search spaces before you add a translation pattern.

Configure translation patterns with different levels of display restrictions.

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.

Configuring the Translation Pattern Parameters

Configure the following parameters from the Cisco CallManager Administration Translation Pattern Configuration window.


Tip For outgoing calls, the translation pattern setting at the terminating end can override the originating Cisco CallManager cluster settings.


Calling Line ID Presentation

Cisco CallManager uses calling line ID presentation as a supplementary service to allow or restrict the originating caller's phone number on a call-by-call basis. Choose one of the following options to allow or restrict the display of the calling party's phone number on the called party's phone display for this translation pattern:

Default—This option does not change the calling line ID presentation.

Allowed—Cisco CallManager allows the display of the calling number.

Restricted—Cisco CallManager 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 CallManager uses connected line ID presentation as a supplementary service to allow or restrict the called party's phone number on a per-call basis. Choose one of the following options to allow or restrict the display of the connected party's phone number on the calling party's phone display for this translation pattern:

Default—This option does not change the connected line ID presentation.

Allowed—This option displays the connected party's phone number.

Restricted—Cisco CallManager blocks the display of the connected party's 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.


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, refer to the Understanding Route Plans chapter in the Cisco CallManager System Guide.


Configuring the Phone Configuration

To complete the configuration of the Call Display Restrictions feature, check the "Ignore Presentation Indicators (internal calls only)" check box from the Cisco CallManager Administration Phone Configuration window.

For use with Extension Mobility, also configure this setting from the Cisco CallManager Administration User Device Profile window.

When you set the "Ignore Presentation Indicators (internal calls only)" field,

Cisco CallManager always displays the remote party's call information if the other party is internal.

Cisco CallManager does not display the remote party's 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 CallManager 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.


Example

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, refer to the Cisco IP Phone Configuration chapter in the Cisco CallManager Administration Guide. For information about device profile configurations, refer to the Device Profile Configuration chapter in the Cisco CallManager Administration Guide.

Sample Call Flow

Figure 17-1 shows a graphic representation of a sample call flow, with a description of how the Call Display Restrictions feature works in this scenario.

Figure 17-1 Sample Call Flow

1. Room-1 calls Room-2 (directory number 222).

2. Room-1 has CSS_FromRoom, so Room-1 can access only phones that are in the P_CallsFromRoomToRoom partition.

3. The P_CallsFromRoomToRoom partition contains 2XX, but it does not contain directory number 222 (Room-2).

4. The call routes to translation pattern TP:2XX, which is configured to restrict display information.

5. The TP:2XX translation pattern can access the P_Room partition because it is configured with the CSS_Room calling search space.

6. The CSS_Room calling search space contains directory number 222 (Room-2).

7. The call connects to Room-2, but theTP:2XX translation pattern restricts the display information.
