Call Park and Directed Call Park


This chapter describes the Call Park feature, which is a hold function, and the Directed Call Park feature, which is a transfer function. Cisco recommends that you treat these two features as mutually exclusive: enable one or the other, but not both. If you do enable both, ensure that the numbers that are assigned to each are exclusive and do not overlap. The information in the following sections will help you utilize these two features to their maximum potential:

Call Park

Directed Call Park

Call Park

The Call Park feature allows you to place a call on hold, so it can be retrieved from another phone in the Cisco Unified Communications Manager system (for example, a phone in another office or in a conference room). If you are on an active call at your phone, you can park the call to a call park extension by pressing the Park softkey or the Call Park button. Someone on another phone in your system can then dial the call park extension to retrieve the call.

You can define either a single directory number or a range of directory numbers for use as call park extension numbers. You can park only one call at each call park extension number.

This chapter provides the following information about call park:

Introducing Call Park

The Call Park feature works within a Cisco Unified Communications Manager cluster, and each Cisco Unified Communications Manager in a cluster must have call park extension numbers defined. (For information about using call park across clusters, see the "Using Call Park Across Clusters" section.) You can define either a single directory number or a range of directory numbers for use as call park extension numbers. Ensure that the directory number or range of numbers is unique.

Valid call park extension numbers comprise integers and the wildcard character, X. You can configure a maximum of XX in a call park extension number (for example, 80XX), which provides up to 100 call park extension numbers. When a call gets parked, Cisco Unified Communications Manager chooses the next call park extension number that is available and displays that number on the phone.

Cisco Unified Communications Manager can park only one call at each call park extension number.


Note If users will use call park across servers in a cluster, ensure each Cisco Unified Communications Manager server in a cluster has call park extension numbers that are configured.See the "Configuring a Call Park Number" section for configuration details.


Using the Call Park Feature

Figure 10-1 illustrates the call park process.

1. User on phone A calls phone B.

2. User on phone A wants to take the call in a conference room for privacy. Phone A user presses the Park softkey.

3. The Cisco Unified Communications Manager server to which phone A is registered sends the first available call park directory, 1234, which displays on phone A. The user on phone A watches the display for the call park directory number (so he can dial that directory number on phone C).

4. The user on phone A leaves the office and walks to an available conference room where the phone is designated as phone C. The user goes off-hook on phone C and dials 1234 to retrieve the parked call.

5. The system establishes call between phones C and B.

Figure 10-1 Call Park Process

Using Call Park Across Clusters

Users can dial the assigned route pattern (for example, a route pattern for an intercluster trunk could be 80XX) and the call park number (for example 8022) to retrieve parked calls from another Cisco Unified Communications Manager cluster. Additionally, you must ensure that calling search spaces and partitions are properly configured.

See the following example.

Example of Retrieving Parked Calls from Another Cluster

Two clusters exist in the network (cluster A and cluster B). Cluster A includes user A1 and user A2. Cluster B includes user B1 and user B2.

Cluster A includes call park numbers in the range of 81xx. Cluster B includes call park numbers in the range of 82xx, which the administrator configured.

Cluster A includes route patterns that are configured to other cluster park ranges as 82xx (routes to Cluster B). Cluster B includes route patterns that are configured to other cluster park ranges as 81xx (routes to Cluster A).

When user A1 parks a call at 8101, all users (which have correct partitions configured) in Cluster A and Cluster B can retrieve the parked call because of the route pattern configuration. When user B1 parks a call at 8202, all users (which have correct partitions configured) in Cluster A and Cluster B can retrieve the parked call because of the route pattern configuration. See Figure 10-2.

Q.SIG Intercluster Trunks

Attendant Console

Cisco Unified Communications Manager Attendant Console uses the Call Park Retrieval Allowed check box (found on the Cisco Unified Communications Manager Administration User Configuration window) when configuring the ac user. See "Enabling Device Security for Cisco Unified Communications Manager Attendant Console" in the Cisco Unified Communications Manager Features and Services Guide for details.

CTI Applications

CTI applications (for example, Attendant Console) access call park functionality, including monitoring activity on call park DNs. To monitor a call park DN, you must add an application or end user that is associated with the CTI application to the Standard CTI Allow Call Park Monitoring user group.

Refer to the "Configuration Checklist for Cisco Unified Communications Manager Attendant Console" section on page 17-17 for details.

Music On Hold

Music on hold allows users to place calls on hold with music that a streaming source provides. Music on hold allows two types of hold:

User hold—The system invokes this type of hold when a user presses the Hold button or Hold softkey.

Network hold—This type of hold takes place when a user activates the transfer, conference, or call park feature, and the hold automatically gets invoked.

Route Plan Report

The route plan report displays the patterns and directory numbers that are configured in Cisco Unified Communications Manager. Use the route plan report to look for overlapping patterns and directory numbers before assigning a directory number to call park. Refer to the Route Plan Report chapter in the Cisco Unified Communications Manager Administration Guide.

Calling Search Space and Partitions

Assign the Call Park directory number or range to a partition to limit call park access to users on the basis of the device calling search space. See Calling Search Space Configuration and Partition Configuration in the Cisco Unified Communications Manager Administration Guide.

Immediate Divert

Call park supports Immediate Divert (iDivert softkey). For example, user A calls user B, and user B parks the call. User B retrieves the call and then decides to send the call to voice-messaging mailbox by pressing the iDivert softkey. User A receives the voice-messaging mailbox greeting of user B.

Barge

The following paragraphs describe the differences between Barge and cBarge with call park.

Barge with Call Park

The target phone (the phone that is being barged upon) controls the call. The barge initiator "piggy backs" on the target phone. The target phone includes most of the common features, even when the target is being barged; therefore, the barge initiator has no feature access. When the target parks a call, the barge initiator then must release its call (the barge).

cBarge with Call Park

The target and barge initiator act as peers. The cBarge feature uses a conference bridge, which makes it behave similar to a MeetMe conference. Both phones (target and barge initiator) have full access to their features.

Directed Call Park

Cisco recommends that you do not configure both directed call park and the Park softkey for call park, but the possibility exists to configure both. If you configure both, ensure that the call park and directed call park numbers do not overlap.

Q.SIG Intercluster Trunks

When a user parks a call across a QSIG intercluster trunk or a QSIG gateway trunk, the caller who has been parked (the parkee) does not see the To parked number message. The phone continues to display the original connected number. The call has been parked, and the user who parked the call can retrieve it. When the call is retrieved from the parked state, the call continues, but the caller who was parked does not see the newly connected number.

Additional Information

See the "Related Topics" section.

Restrictions

The following restrictions apply to call park:

Cisco Unified Communications Manager can park only one call at each call park extension number.

Ensure each call park directory number, partition, and range is unique within the Cisco Unified Communications Manager cluster.

For shared line devices across nodes, the line will register to the node on which the device registers first. For example, if a device from subscriber2 registers first and the line is created in subscriber2 and the publisher server, the line belongs to subscriber2. Each node must be configured with the call park number.

To achieve failover/fallback, configure call park numbers on the publisher server and subscriber nodes. With this configuration, when the primary node is down, the line/device association gets changed to the secondary node, and the secondary node call park number gets used.

Each Cisco Unified Communications Manager to which devices are registered needs its own unique call park directory number and range.

Cisco Unified IP Phone 7902 cannot park a call (retrieval of parked calls only).

Cisco Unified Communications Manager Administration does not validate the call park numbers or range that you use to configure call park. To help identify invalid numbers or ranges and potential range overlaps, use the Cisco Unified Communications Manager Dialed Number Analyzer tool.

Cisco Unified Communications Manager Administration does not check that the value that is entered for Call Park Reversion Timer is less than the value that is entered for the Call Park Display Timer. If you entered a Call Park Reversion Timer value that is less than the Call Park Display Timer, call park numbers will not display on the phone.

See the "Configuring a Call Park Number" section for configuration details.

Setting the Service Parameters for Call Park

Cisco Unified Communications Manager provides two clusterwide service parameters for call park: Call Park Display Timer and Call Park Reversion Timer. Each service parameter includes a default and requires no special configuration.

Call Park Display Timer—Default specifies 10 seconds. This parameter determines how long a call park number displays on the phone that parked the call. Set this timer for each server in a cluster that has the Cisco CallManager service and call park configured.

Call Park Reversion Timer—Default specifies 60 seconds. This parameter determines the time that a call remains parked. Set this timer for each server in a cluster that has the Cisco CallManager service and call park configured. When this timer expires, the parked call returns to the device that parked the call.


Note To set the timers, choose System > Service Parameters and update the Call Park Display Timer and the Call Park Reversion Timer fields in the Clusterwide Parameters (Feature-General) pane.


Additional Information

See the "Related Topics" section.

Finding a Call Park Number

Directed Call Park

Directed Call Park allows a user to transfer a call to an available user-selected directed call park number. Configure directed call park numbers in the Cisco Unified Communications Manager Directed Call Park Configuration window. Configured directed call park numbers exist clusterwide. You can configure phones that support the directed call park Busy Lamp Field (BLF) to monitor the busy/idle status of specific directed call park numbers. Users can also use the BLF to speed dial a directed call park number. See Interactions and Restrictions, for a list of the phone models that support the BLF.

Introducing Directed Call Park

Cisco Unified Communications Manager can park only one call at each directed call park number. To retrieve a parked call, a user must dial a configured retrieval prefix followed by the directed call park number at which the call is parked. Configure the retrieval prefix in the Directed Call Park Configuration window.

Example 10-1 Using the Directed Call Park Feature

The following examples illustrate how the directed call park feature can be used.

1. Users A1 and A2 connect in a call.

2. To park the call, A1 presses the Transfer softkey (or Transfer button, if available) and dials directed call park number 80 (for example) or presses the BLF button for directed call park number 80 (if the phone model supports the BLF button).

3. A1 either presses the Transfer softkey (or Transfer button) again or goes on hook to complete the directed call park transfer. This action parks A2 on directed call park number 80.


Note The user can complete the transfer only by going on hook rather than pressing the Transfer softkey (or Transfer button) a second time if the Transfer On-hook Enabled service parameter is set to True. See "Onhook Call Transfer" in the Cisco Unified Communications Manager System Guide.


4. From any phone with a correctly configured partition and calling search space, user B1 dials the directed call park prefix (21, for example) followed by the directed call park number 80 to retrieve the call. B1 connects to A2.

Example 10-2 Using the Directed Call Park Feature

1. Users A1 and A2 connect in a call.

2. To park the call, A1 presses the Transfer softkey (or Transfer button, if available) and dials directed call park number 80 (for example) or presses the BLF button for directed call park number 80 (if the phone model supports the BLF button).

3. A1 either presses the Transfer softkey (or Transfer button) again or goes on hook to complete the directed call park transfer. This action parks A2 on directed call park number 80.


Note The user can complete the transfer only by going on hook rather than pressing the Transfer softkey (or Transfer button) a second time if the Transfer On-hook Enabled service parameter is set to True. See "Onhook Call Transfer" in the Cisco Unified Communications Manager System Guide.


4. The call does not get retrieved before the Call Park Reversion Timer (service parameter) expires.

5. A2 reverts to the configured reversion number.

Additional Information

See the "Related Topics" section.

System Requirements for Directed Call Park

To operate, Directed Call Park requires the following software component:

Cisco Unified Communications Manager 6.0 or later

A user can park and retrieve a call by using directed call park from any phone that can perform a transfer including Cisco Unified IP Phones 7905, 7912, 7920, 7940, 7960, and 7970. Cisco VG248 Analog Phone Gateways also support directed call park.

The following SCCP and SIP phones support directed call park BLF:

Cisco Unified IP Phones (7941, 7961, 7970, 7971)

The following SCCP phones support directed call park BLF:

Music on hold allows users to place calls on hold with music that is provided from a streaming source. Music on hold allows two types of hold:

User hold—The system invokes this type of hold when a user presses the Hold button or Hold softkey.

Network hold—This type of hold takes place when a user activates the transfer, conference, or call park feature, and the hold automatically gets invoked. This hold type applies to directed call park because directed call park is a transfer function.

Route Plan Report

The route plan report displays the patterns and directory numbers that are configured in Cisco Unified Communications Manager. Use the route plan report to look for overlapping patterns and directory numbers before assigning a directory number to directed call park. Refer to the Route Plan Report chapter in the Cisco Unified Communications Manager Administration Guide.

cBarge with Directed Call Park

The target and barge initiator act as peers. The cBarge feature uses a conference bridge that makes it behave similar to a meet-me conference. Both phones (target and barge initiator) retain full access to their features.

Call Park

Cisco recommends that you do not configure both directed call park and the Park softkey for call park, but the possibility exists to configure both. If you configure both, ensure that the call park and directed call park numbers do not overlap.

A caller who has been parked (the parkee) by using the directed call park feature cannot, while parked, use the standard call park feature.

Restrictions

The following restrictions apply to directed call park:

Cisco Unified Communications Manager can park only one call at each directed call park number.

Ensure each directed call park directory number, partition, and range is unique within the Cisco Unified Communications Manager cluster. If the Park softkey is also activated (not recommended), ensure that no overlap exists between call park numbers and directed call park numbers.

A caller who has been parked (the parkee) by using the directed call park feature cannot, while parked, use the standard call park feature.

The directed call park BLF cannot monitor a range of directed call park numbers. A user can monitor only individual directed call park numbers by using the directed call park BLF. For example, if you configure a directed call park number range 8X, you cannot use the directed call park BLF to monitor that whole range of 80 to 89.

Attendant console attendants must use the Consult Transfer button to send calls to a directed call park number. If they use the Transfer button, the system cannot revert the call to the attendant when the reversion timer expires, and the caller receives a reorder tone.

You cannot delete a directed call park number that a device is configured to monitor (using the BLF button). A message indicates that the directed call park number or range cannot be deleted because it is in use. To determine which devices are using the number, click the Dependency Records link on the Directed Call Park Configuration window.

If reversion number is not configured, the call reverts to the parker (parking party) after the call park reversion timer expires. Directed Call Park for SIP phones is designed as busy lamp field (BLF) plus call transfer (to a park code). The transfer functionality remains the same as for SCCP phones. The following limitations apply to directed call park for SIP phones:

Directed call park gets invoked by using the transfer softkey on Cisco SIP IP Phones 7940 and 7960.

The system does not support directed call park when the blind transfer softkey is used on Cisco SIP IP Phones 7940 and 7960.

The system does not support directed call park BLF on Cisco SIP IP Phones 7940 and 7960, and third-party SIP phones.

The following Cisco SIP IP Phones support directed call park BLF: 7941, 7961, 7970, and 7971.

See the "Configuring a Directed Call Park Number" section for configuration details.

Additional Information

See the "Related Topics" section.

Installing and Activating Directed Call Park

Directed call park system feature comes standard with Cisco Unified Communications Manager software. Any phone that can perform a transfer can use directed call park. It does not require special installation. Cisco recommends that you configure either call park or directed call park, but not both. If you do configure both, ensure that the directed call park and call park numbers do not overlap.

Configuration Steps
Related procedures and topics

Step 1 

Configure a partition for directed call park numbers to make the partition available only to users who have the partition in their calling search space. To successfully retrieve a parked call, the calling search space from which the user is retrieving the call must contain the partition that includes the directed call park number.

Configuring a Partition, Cisco Unified Communications Manager Administration Guide

Media Termination Point Configuration, Cisco Unified Communications Manager Administration Guide

Calling Search Space Configuration, Cisco Unified Communications Manager Administration Guide

Step 2 

Configure a unique directed call park number or define a range of directed call park numbers. You must specify a range by using wildcards. For example, the range 40XX configures the range as 4000 to 4099.


Caution Do not enter a range by using dashes (such as 4000-4040).

Note You can monitor only individual directed call park numbers with the directed call park BLF. If you configure a range of numbers, the BLF cannot support monitoring of the busy/idle status of the range or of any number within the range.

Configuring a Directed Call Park Number

Step 3 

Assign the Standard User softkey template to each device that has directed call park access. For phones that do not use softkeys, the phone button template with the Transfer button automatically gets configured.

Softkey Template Configuration, Cisco Unified Communications Manager Administration Guide

Step 4 

For phone models that support the directed call park BLF, configure the phone button template to include one or more Call Park BLF buttons and configure the directed call park BLF settings.

Guidelines for Customizing Phone Button Templates, Cisco Unified Communications Manager System Guide

Configuring BLF/Directed Call Park Buttons

Step 5 

Notify users that the directed call park feature is available.

Refer to the phone documentation for instructions on how users access directed call park features on their Cisco Unified IP Phone.

Additional Information

See the "Related Topics" section.

Setting the Service Parameters for Directed Call Park

The Call Park Reversion Timer clusterwide service parameter affects directed call park. This parameter determines the time that a call remains parked. The default specifies 60 seconds. When the timer expires, the parked call returns to either the device that parked the call or to another specified number, depending on what you configure in the Directed Call Park Configuration window.

Additional Information

See the "Related Topics" section.

Finding a Directed Call Park Number

Because you may have several directed call park numbers in your network, Cisco Unified Communications Manager lets you locate specific directed call park numbers on the basis of specific criteria. Use the following procedure to locate directed call park numbers.


Note During your work in a browser session, Cisco Unified Communications Manager Administration retains your directed call park number search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified Communications Manager Administration retains your directed call park number search preferences until you modify your search or close the browser.


Procedure


Step 1 Choose Call Routing > Directed Call Park.

The Find and List Directed Call Park Numbers window displays.

Step 2 To find all records in the database, ensure the dialog box is empty; go to Step 3.

To filter or search records:

From the first drop-down list box, select a search parameter.

From the second drop-down list box, select a search pattern.

Specify the appropriate search text, if applicable.


Note To add additional search criteria, click the + button. When you add criteria, the system searches for a record that matches all criteria that you specify. To remove criteria, click the - button to remove the last added criteria or click the Clear Filter button to remove all added search criteria.


Step 3 Click Find.

All or matching records display. You can change the number of items that display on each page by choosing a different value from the Rows per Page drop-down list box.


Note You can delete multiple records from the database by checking the check boxes next to the appropriate record and clicking Delete Selected. You can delete all configurable records for this selection by clicking Select All and then clicking Delete Selected.


Step 4 From the list of records that display, click the link for the record that you want to view.


Note To reverse the sort order, click the up or down arrow, if available, in the list header.


The window displays the item that you choose.

Configuring a Directed Call Park Number

This section describes how to add, copy, and update a single directed call park extension number or range of extension numbers.

Procedure


Step 1 Choose Call Routing > Directed Call Park.

Step 2 Perform one of the following tasks:

To add a new Directed Call Park Number, click Add New.

To copy a Directed Call Park Number, use the procedure in the "Finding a Directed Call Park Number" section to locate the directed call park number or range of numbers. Click the Copy icon.

To update a Directed Call Park Number, use the procedure in the "Finding a Directed Call Park Number" section to locate the directed call park number or range of numbers.

The Directed Call Park Number Configuration window displays.

Step 3 Enter or update the appropriate settings as described in Table 10-4.

Step 4 To save the new or changed call park numbers in the database, click Save.



Note Updating a directed call park number causes Cisco Unified Communications Manager to immediately revert any call that is parked on that number. This occurs because, when you update a directed call park number, Cisco Unified Communications Manager actually deletes the old information and then adds the new information. At the point that the old information is deleted, a parked call on that number cannot remain parked or be retrieved in the usual way and must be reverted.



Note Whenever changes are made to directed call park numbers or ranges, any devices that are configured to monitor those directed call park numbers by using the BLF must restart to correct the display. Change notification automatically restarts impacted devices when it detects directed call park number changes. You can also use the Restart Devices button on the Directed Call Park Configuration window.

Directed Call Park Configuration Settings

Table 10-4 describes the directed call park configuration settings.

Table 10-4 Directed Call Park Configuration Settings 

Field
Description

Number

Enter the directed call park number. You can enter literal digits or the wildcard character X (the system allows one or two Xs). For example, enter 5555 to define a single call park number of 5555 or enter 55XX to define a range of directed call park extension numbers from 5500 to 5599. Make sure that the directed call park numbers are unique and that they do not overlap with call park numbers.

Description

Provide a brief description of this directed call park number or range.

Partition

If you want to use a partition to restrict access to the directed call park numbers, choose the desired partition from the drop-down list box. If you do not want to restrict access to the directed call park numbers, leave the partition as the default of <None>.

See Searching for a Partition in the Cisco Unified Communications Manager Administration Guide for instructions on finding a partition when there are a large number of them configured.

Note Make sure that the combination of directed call park number and partition is unique within the Cisco Unified Communications Manager cluster.

Reversion Number

Enter the number to which you want the parked call to return if not retrieved, or leave the field blank.

Note A reversion number can comprise digits only; you cannot use wildcards.

Reversion Calling Search Space

Using the drop-down list box, choose the calling search space or leave the calling search space as the default of <None>.

Retrieval Prefix

For this required field, enter the prefix for retrieving a parked call. The system needs the retrieval prefix to distinguish between an attempt to retrieve a parked call and an attempt to initiate a directed park.



Note Whenever changes are made to directed call park numbers, any devices that are configured to monitor those directed call park numbers by using the directed call BLF must restart to correct the display. Change notification automatically restarts impacted devices when it detects directed call park number changes. You also can use the Restart Devices button on the Directed Call Park Configuration window.

Configuring BLF/Directed Call Park Buttons

To configure BLF/Directed Call Park buttons, perform the following procedure:

Procedure


Step 1 To configure the BLF/Directed Call Park button in the Phone Configuration window, find the phone, as described in the "Cisco Unified IP Phone Configuration" chapter in the Cisco Unified Communications Manager Administration Guide.

Step 2 To configure the BLF/Directed Call Park button for user device profiles, find the user device profile as described in the "Device Profile Configuration" chapter in the Cisco Unified Communications Manager Administration Guide.

Step 3 After the configuration window displays, click the Add a new BLF Directed Call Park link in the Association Information pane.


Tip The link does not display in the Association Information pane if the phone button template that you applied to the phone or device profile does not support BLF/Directed Call Park.


Step 4 Configure the settings, as described in Table 10-5.

Step 5 After you complete the configuration, click Save and close the window.

The directory number(s) display in the Association Information pane of the Phone Configuration Window.


Additional Information

See the "Related Topics" section.

BLF/Directed Call Park Configuration Settings

Table 10-5 describes the settings that you configure for BLF/Directed Call Park buttons.

Table 10-5 BLF/Directed Call Park Button Configuration Settings 

Field
Description

Directory Number

The Directory Number drop-down list box displays a list of directory numbers that exist in the Cisco Unified Communications Manager database.

For SCCP or SIP phones, choose the number (and corresponding partition, if it displays) that you want the system to dial when the user presses the speed-dial button; for example, 6002 in 3. Directory numbers that display without specific partitions belong to the default partition.

Label

Enter the text that you want to display for the BLF/Directed Call Park button.

This field supports internationalization. If your phone does not support internationalization, the system uses the text that displays in the Label ASCII field.

Label ASCII

Enter the text that you want to display for the BLF/Directed Call Park button.

The ASCII label represents the noninternationalized version of the text that you enter in the Label field. If the phone does not support internationalization, the system uses the text that displays in this field.

Tip If you enter text in the Label ASCII field that differs from the text in the Label field, Cisco Unified Communications Manager Administration accepts the configuration for both fields, even though the text differs.

Deleting a Directed Call Park Number

This section describes how to delete directed call park numbers from the Cisco Unified Communications Manager database.

Procedure


Step 1 Using the procedure in the "Finding a Directed Call Park Number" section, locate the directed call park number or range of numbers.

Step 2 Click the directed call park number or range of numbers that you want to delete.

Step 3 Click Delete.



Note Deleting a directed call park number causes Cisco Unified Communications Manager to immediately revert any call that is parked on that number. This occurs because, when the number is deleted, a parked call on that number cannot remain parked or be retrieved in the usual way and must be reverted.



Note You cannot delete a directed call park number that a device is configured to monitor (using the BLF button). A message indicates that the directed call park number cannot be deleted because it is in use. To determine which devices are using the number, click the Dependency Records link in the Directed Call Park Configuration window.
