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 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.

Introducing Call Park

The Call Park feature works within a Cisco CallManager cluster, and each Cisco 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 CallManager chooses the next call park extension number that is available and displays that number on the phone.

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

---

Note Each Cisco 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 8-1 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 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 8-1 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 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 (these are configured by the administrator).

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 8-2.

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

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

•Cisco IP Phone Model 7910

Interactions and Restrictions

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

Interactions

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

•Attendant Console

•Music On Hold

•Route Plan Report

•Calling Search Space and Partitions

•Immediate Divert

•Barge

Attendant Console

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

Restrictions

The following restrictions apply to Call Park:

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

•Ensure each Call Park directory number, partition, and range are unique within the Cisco CallManager cluster.

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

•Cisco IP Phone 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 CallManager software. It does not require special installation.

Step 5	In the User Configuration window for each user that is allowed to access the call park feature, check the Call Park Retrieval Allowed check box.	Adding a New User, Cisco CallManager Administration Guide
Step 6	Notify users that the call park feature is available.	Refer to the phone documentation for instructions on how users access call park features on their Cisco IP Phone.

Setting the Service Parameters for Call Park

Cisco CallManager 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.

Finding a Call Park Number

Because you might have several call park numbers in your network, Cisco 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 CallManager Administration retains your call park number search preferences. If you navigate to other menu items and return to this menu item, Cisco CallManager Administration retains your call park number search preferences until you modify your search or close the browser.

Troubleshooting Call Park

Table 8-3 provides troubleshooting recovery tips for common call park problems.

Table 8-3 Troubleshooting Tips for Call Park 

Problem Description	Recommended Action
User cannot park calls. When the user presses the Park softkey or feature button, the call does not get parked.	Ensure that a unique call park number is assigned to each Cisco CallManager in the cluster. See the "Adding a Call Park Number" section. The partition that is assigned to the call park number does not match the partition that is assigned to the phone directory number. See the "Adding a Call Park Number" section and the "Adding a Directory Number" section in the Cisco CallManager Administration Guide.
The call park number does not display long enough for the user.	Set the Call Park Display Timer to a longer duration. See the "Setting the Service Parameters for Call Park" section.
