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 CallManager 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 CallManager cluster, and each Cisco Unified CallManager 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 CallManager chooses the next call park extension number that is available and displays that number on the phone.

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


Note Each Cisco Unified CallManager server in a cluster must have call park extension numbers configured if users will use call park across servers in a cluster. See the "Adding a Call Park Number" section for configuration details.


Using the Call Park Feature

Figure 9-1 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 CallManager server to which phone A is registered sends the first available call park directory, 1234, which is displayed 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. The phone in the conference room 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 9-1 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 CallManager 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 (the administrator configures these ranges).

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 9-2.

Figure 9-2 Retrieving Parked Calls by Using Intercluster Trunks

System Requirements for Call Park

To operate, Call Park requires the following software components:

Cisco CallManager 3.0 or later

The following phones support Call Park with the Park softkey in the Standard User and Standard Feature softkey templates:

Cisco Unified IP Phones (Models 7905, 7912, 7920, 7940, 7960, 7970)

The following phones support Call Park with the Call Park button on the phone button template:

Cisco Unified IP Phone Model 30 (30 SP+ and 30 VIP)

Cisco Unified IP Phone Model 12 (12 S, 12 SP, 12 SP+)

Cisco Unified IP Phone Model 7910

Interactions and Restrictions

The following sections describe the interactions and restrictions for the Call Park feature.

Interactions

Restrictions

Interactions

The following sections describe how Call Park interacts with Cisco Unified CallManager applications and call processing:

Attendant Console

Music On Hold

Route Plan Report

Calling Search Space and Partitions

Immediate Divert

Barge

Directed Call Park

Attendant Console

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

Music On Hold

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 is automatically invoked.

Route Plan Report

The route plan report displays the patterns and directory numbers that are configured in Cisco Unified CallManager. 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 CallManager 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 CallManager 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, making 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.

Restrictions

The following restrictions apply to the Call Park feature:

Cisco Unified CallManager 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 CallManager cluster.

Each Cisco Unified CallManager to which devices are registered needs its own unique Call Park directory number and range.

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

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

Installing and Activating Call Park

Call Park, a system feature, comes standard with Cisco Unified CallManager software. It does not require special installation.

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

Setting the Service Parameters for Call Park

The Cisco CallManager service 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 directed 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 directed call park configured. When this timer expires, the parked call returns to the device that parked the call.

Finding a Call Park Number

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


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

Directed Call Park

Directed Call Park allows a user to transfer a parked call to an available user-selected directed call park number. Configure directed call park numbers in the Cisco Unified CallManager 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 System Requirements for Directed Call Park, for a list of the phone models that support the BLF.

Introducing Directed Call Park

Cisco Unified CallManager 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 9-1 Using the Directed Call Park Feature

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

1. Users A1 and A2 are connected.

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, Cisco Unified CallManager 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 9-2 Using the Directed Call Park Feature

1. Users A1 and A2 are connected.

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, Cisco Unified CallManager System Guide.


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

5. A2 reverts to the number that parked the call (if the Cisco Unified CallManager Administrator configured the directed call park number with Use Originator as the reversion option) or to another directory number (if the Cisco Unified CallManager Administrator configured the directed call park number with Use Specified Number as the reversion option).

System Requirements for Directed Call Park

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

Cisco Unified CallManager 4.2 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 Phone models 7905, 7912, 7920, 7940, 7960, and 7970. Cisco VG248 Analog Phone Gateways also support directed call park.

The following phones can monitor the busy/idle status of a directed call park number by using the directed call park Busy Lamp Field (BLF):

Cisco Unified IP Phone Models 7940 and 7941

Cisco Unified IP Phone Models 7960 and 7961

Cisco Unified IP Phone Models 7970 and 7971

Cisco Unified IP Phone Expansion Module 7914

Attendant Console

The Cisco Unified CallManager Administration User Configuration window does not include any configuration or activation for directed call park as it does for call park. See Restrictions, for additional information about directed call park with attendant console.

Music On Hold

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 CallManager. 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 CallManager Administration Guide.

Calling Search Space and Partitions

Assign the directed call park directory number or range to a partition to limit directed 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 CallManager Administration Guide.

Immediate Divert

Directed 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 directed call park.

Barge with Directed 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 using directed call park, the barge initiator then must release its call (the barge).

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 CallManager 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 CallManager 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.

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

Installing and Activating Directed Call Park

Directed call park system feature comes standard with Cisco Unified CallManager 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.

Adding a Partition, Cisco Unified CallManager Administration Guide

Media Termination Point Configuration, Cisco Unified CallManager Administration Guide

Calling Search Space Configuration, Cisco Unified CallManager 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.

Adding 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 CallManager 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 CallManager System Guide

Configuring Directed Call Park Busy Lamp Field Settings, Cisco Unified CallManager Administration Guide

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.

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.

Finding a Directed Call Park Number

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

Updating a Directed Call Park Number

This section describes how to update a directed call park extension number or range of numbers.

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 update.

Step 3 Update the appropriate settings as described in Table 9-5.

Step 4 To save the changes in the database, click Update.



Note Updating a directed call park number causes Cisco Unified CallManager to immediately revert any call that is parked on that number. This occurs because, when you update a directed call park number, Cisco Unified CallManager 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.

Field
Description

Directed Call Park Number/Range

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>.

If more than 250 partitions exist, the ellipsis (...) button displays next to the drop-down list box. Click the ... button to display the Select Partition window. Enter a partial partition name in the List items where Name contains field. Click the desired partition name in the list of partitions that displays in the Select item to use box and click OK.

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

Reversion Number

You have a choice of two radio buttons:

Select Use Originator if you want the parked call to return to the originating number if not retrieved.

Select Use Specified Number if you want the parked call to return to a different number if not retrieved. Enter the specified number in the space that is provided.

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

Calling Search Space

If you provide a specified number as the reversion number, you can specify a 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>.

If more than 250 calling search spaces exist, the ellipsis (...) button displays next to the drop-down list box. Click the ... button to display the Select Calling Search Space window. Enter a partial calling search space name in the List items where Name contains field. Click the desired calling search space name in the list of calling search spaces that displays in the Select item to use box and click OK.

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.

Troubleshooting Directed Call Park

Table 9-6 provides troubleshooting recovery tips for common directed call park problems.

Table 9-6 Troubleshooting Tips for Directed Call Park 

Problem Description
Recommended Action

User cannot park calls. After the Transfer softkey (or Transfer button if available) is pressed and the directed call park number is dialed, the call does not get parked.

Ensure that the partition that is assigned to the call park number matches the partition that is assigned to the phone directory number. See the "Adding a Directed Call Park Number" section and the "Adding a Directory Number" section in the Cisco Unified CallManager Administration Guide.

Ensure that the partition and calling search space are configured correctly for the device. See Calling Search Space Configuration and Partition Configuration in the Cisco Unified CallManager Administration Guide.

User cannot park calls. After pressing the Transfer softkey (or Transfer button if available) and dialing the directed call park number, the user receives a busy tone, and the IP phone displays the message, Park Slot Unavailable.

Ensure that the dialed directed call park number is not already occupied by a parked call or park the call on a different directed call park number.

User cannot park calls. After pressing the Transfer softkey (or Transfer button if available) and dialing the directed call park number, the user receives a reorder tone or announcement.

Ensure that the dialed number is configured as a directed call park number. See the "Finding a Directed Call Park Number" section and the "Adding a Directed Call Park Number" section.

Parked calls revert too quickly.

Set the Call Park Reversion Timer to a longer duration. See the "Setting the Service Parameters for Directed Call Park" section.

User cannot park calls. The user receives a reorder tone after the reversion timer expires.

Ensure that the user presses the Transfer softkey (or Transfer button if available) before dialing the directed call park number, then presses the Transfer softkey (or Transfer button) again or goes on hook after dialing the directed call park number. Because directed call park is a transfer function, the directed call park number cannot be dialed alone. See the "Introducing Directed Call Park" section.

Note You 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, Cisco Unified CallManager System Guide.

User cannot retrieve parked calls. After dialing the directed call park number to retrieve a parked call, the user receives a busy tone, and the IP phone displays the message, Park Slot Unavailable.

Ensure that the user dials the retrieval prefix followed by the directed call park number. See the "Introducing Directed Call Park" section.

Parked calls do not revert to the number that parked the call.

Check the configuration of the directed call park number to ensure that it is configured to revert to the number that parked the call rather than to a different directory number. See the "Configuring Directed Call Park" section.

When an attempt is made to delete a directed call park number or range, a message displays that indicates that the number or range cannot be deleted because it is in use.

You cannot delete a directed call park number that a device is configured to monitor (by using the BLF button). To determine which devices are using the number, click the Dependency Records link on the Directed Call Park Configuration window.

After configuring a range of directed call park numbers, user cannot park a call at a number within the range.

Review the syntax for entering a range of directed call park numbers. If incorrect syntax is used, the system may appear to configure the range when it actually does not. See the "Adding a Directed Call Park Number" section.
