Call Park Enhancements in Cisco Unified CME 7.1

Cisco Unified CME 7.1 adds Call Park support for SIP phones, introduces Park Reservation Groups, and enhances the Directed Call Park feature. Park slots can be shared among SCCP and SIP phones. For example, a call parked on a SCCP phone can be retrieved by a SIP phone on the same Cisco Unified CME router. Call Park features are available on SCCP and SIP phones that support the Park soft key. The Park soft key displays on supported phones by default.

Table 11 describes how phone users park and retrieve calls in Cisco Unified CME 7.1 and later versions compared to previous versions. For SCCP phones, the only change is in how users perform Directed Call Park Retrieval. The Call Park method supported in previous versions of Cisco Unified CME is enabled by default. You can change the park and retrieval method only when there are no parked calls.

To enable Call Park features, see the "Enabling Call Park or Directed Call Park" section.

Basic Call Park

The Call Park feature allows a phone user to place a call on hold at a special extension so it can be retrieved from any other phone in the system. A user parks the call at the extension, known as the call-park slot, by pressing the Park soft key. Cisco Unified CME chooses the next available call-park slot and displays that number on the phone. A user on another phone can then retrieve the call by dialing the extension number of the call-park slot.

You can define either a single extension number or a range of extension numbers to use as call-park slots. Each call-park slot can hold one call at a time so the number of calls that users can park is equal to the number of slots you create. If the secondary number is used to group calls together, calls are retrieved in the order in which they were parked; the call that has been parked the longest is the first call retrieved from the call-park slot.

A caller who is parked in a park slot hears the music-on-hold (MOH) audio stream if the call uses the G.711 codec or if the call uses G.729 with transcoding; otherwise, callers hear a tone on hold. Users who attempt to park a call at a busy slot hear a busy tone.

Call-park slots can also be monitored by assigning the call-park slot to a monitor button using the button m command. The line status shows "in use" when a call is parked in the monitored slot. A call that is parked on the monitored call-park slot can be picked up by pressing the assigned monitor button.

You can create a call-park slot that is reserved for use by one extension by assigning that slot a number whose last two digits are the same as the last two digits of the extension. When an extension starts to park a call, the system searches first for a call-park slot that has the same final two digits as the extension. If no such call-park slot exists, the system chooses an available call-park slot.

Multiple call-park slots can be created with the same extension number so that more than one call can be parked for a particular department or group of people at a known extension number. For example, at a hardware store, calls for the plumbing department can be parked at extension 101, calls for lighting can be parked at 102, and so forth. Everyone in the plumbing department knows that calls parked at 101 are for them and can pick up calls from extension 101. When multiple calls are parked at the same call-park slot number, they are picked up in the order in which they were parked; that is, the call that has been parked the longest is the first call picked up from that call-park slot number.

If multiple call-park slots use the same extension number, you must configure each ephone-dn that uses the extension number with the no huntstop command, except for the last ephone-dn to which calls are sent. In addition, each ephone-dn must be configured with the preference command. The preference numeric values must increase to match the order of the ephone-dns. That is, the lowest ephone-dn tag park-slot must have the lowest numeric preference number, and so forth. Without the configuration of the preference and huntstop commands, all calls that are parked after a second call has been parked will generate a busy signal. The caller who is being transferred to park will hear a busy signal, while the phone user who parked the call will receive no indication that the call was lost.

A reminder ring can be sent to the extension that parked the call by using the timeout keyword with the park-slot command. The timeout keyword and argument set the interval length during which the call-park reminder ring is timed out or inactive. If the timeout keyword is not used, no reminder ring is sent to the extension that parked the call. The number of timeout intervals and reminder rings are configured with the limit keyword and argument. For example, a limit of 3 timeout intervals sends 2 reminder rings (interval 1, ring 1, interval 2, ring 2, interval 3). The timeout and limit keywords and arguments also set the maximum time that calls stay parked. For example, a timeout interval of 10 seconds and a limit of 5 timeout intervals (park-slot timeout 10 limit 5) will park calls for approximately 50 seconds.

The reminder ring is sent only to the extension that parked the call unless the notify keyword is also used to specify an additional extension number to receive a reminder ring. When an additional extension number is specified using the notify keyword, the phone user at that extension can retrieve a call from this slot by pressing the PickUp soft key and the asterisk (*) key.

You can define both the length of the timeout interval for calls parked at a call-park slot and the number of timeout intervals that should occur before the call is either recalled or transferred. If you specify a transfer target in the park-slot command, the call is transferred to the specified target after the timeout intervals expire rather than to the primary number of the parking phone.

If a name has been specified for the call-park slot using the name command, that name will be displayed on a recall or transfer rather than an extension number.

You can also specify an alternate target extension at which to transfer a parked call if the recall or transfer target is in use (ringing or connected). For example, a call is parked at the private park slot for the phone with the primary extension of 2001, as shown in Figure 7. After the timeouts expire, the system attempts to recall the call to extension 2001, but that line is connected to another call. The system then transfers the call to the alternate target, extension 3784.

Directed Call Park

The Directed Call Park feature allows a phone user to transfer a call to a specific call-park slot using the Transfer soft key. For example, a customer calls a retail store and asks for the sporting goods department. The operator who answers the call transfers the call to one of the park-slots associated with the sporting goods department and pages the sporting goods department to retrieve the call. You can configure phones that support the directed call-park Busy Lamp Field (BLF) to monitor the busy and idle status of specific directed call-park slots.

In versions before Cisco Unified CME 4.0, callers can directly dial call-park slot numbers to be placed in park. If another call is already parked in the slot, the caller hears a busy tone.

In Cisco Unified CME 4.0 to Cisco Unified CME 7.0, users retrieve a call from a directed call-park slot by dialing the park-slot extension or using the PickUp soft key and dialing the park-slot extension. If no call is parked in the slot, the caller hears a busy tone.

In Cisco Unified CME 7.1 and later versions, users retrieve a call from a directed call-park slot by dialing a feature access code (FAC) and the number of the call-park slot.

Cisco Unified CME supports Directed Call Park from remote phones, however only phones that are local to the directed call-park slot can retrieve a call.

Park Reservation Groups

Cisco Unified CME 7.1 and later versions allow you to assign ownership to call-park slots by using Park Reservation Groups. A park slot configured with a park reservation group can only be used by phones configured with the same park reservation group. A park slot without a park reservation group can be used by any phone not assigned to a park reservation group.

In versions earlier than Cisco Unified CME 7.1, you could reserve a dedicated call-park slot for a specific phone based on its primary line. All lines on that phone could use the dedicated park slot. The new Park Reservation Group feature in Cisco Unified CME 7.1 provides an enhanced method of reserving park slots that replaces the use of dedicated park slots.

Park reservation groups are not supported for directed call-park slots.


Note The reservation-group is used so that the phone with a reservation group is allowed to park to park-slot(s) within the same reservation group.
Any phone within the same CME can retrieve any parked calls. So the rule is applied when you park the call, not when you retrieve the call.


Dedicated Call-Park Slots

A dedicated, private call-park slot can be configured for an ephone using the reserved-for keyword in the park-slot command. The dedicated call-park slot is associated with the primary extension of the ephone. All extensions on this phone can park calls in the dedicated park slot. The extensions on this phone are the only extensions that can park a call in the dedicated park slot. Only one call at a time can be parked in a park slot; a busy tone is returned to any attempt to park a call in a slot that is already in use.

Calls can be parked in dedicated call-park slots using any of the following methods (the extension doing the parking must be on a phone whose primary extension is associated with a dedicated park slot).

With an active call, an IP phone user presses the Park soft key.

With an active call, an IP phone user presses the Transfer soft key and a standard or custom FAC (feature access code) for the call-park feature. The standard FAC for call park is **6.

With an active call, an analog phone user presses hookflash and the standard or custom FAC for the call park feature.

Calls can be retrieved from dedicated call-park slots using any of the following methods:

An IP phone user presses the Pickup soft key and dials the park-slot number.

An IP phone user presses the New Call soft key and dials the park-slot number.

An analog phone user lifts the handset, presses the standard or custom FAC for directed call pickup, and dials the park-slot number. The standard FAC for directed pickup is **5.

If no dedicated park slot is found anywhere in the Cisco Unified CME system for an ephone-dn that is attempting to park a call, the system uses the standard call-park procedure; that is, the system searches for a preferred park slot (one with an ephone-dn number that matches the last two digits of the ephone-dn attempting to park the call) and if none is found, uses any available call-park slot.

Figure 7 shows an example of a dedicated call-park slot.

If the configuration specifies that a call should be recalled to the parking phone after the timeout intervals expire, the call is always returned to the phone's primary extension number, regardless of which extension on the phone did the parking. Figure 7 shows an ephone that is configured with the extension numbers 2001, 2002, and 2003, and a private call-park slot at extension 3333. The private park slot has been set up to recall calls to the parking phone when the parked call's timeouts expire. In the example, extension 2003 parks a call using the Park soft key. When the timeout intervals expire, the call rings back on extension 2001.

The configuration in Figure 7 specifies that the call will recall or transfer from the park slot after 3 times the 60-second timeout, or after 180 seconds. Also, before the exhaustion of the 3 timeouts the phone will receive reminder notifications that a parked call is waiting. The reminders are sent after each 60-second timeout interval expires (that is, at 60 seconds and at 120 seconds). You may want to set the timeout command with a limit of 1 instead, so that the call simply parks and recalls or transfers without sending a reminder ring.

Figure 7 Dedicated Call Park Example

Call-Park Blocking

In Cisco Unified CME 4.0 and later versions, individual ephones can be prevented from making transfers to call-park slots by using the transfer-park blocked command. This command prevents transfers to park that use the Transfer soft key and a call-park slot number, while allowing call-parks that use only the Park soft key. (To prevent use of the Park soft key, use an ephone template to remove it from the phone. See "Customizing Soft Keys".)

An exception is made for phones with reserved, or dedicated, park slots. If the transfer-park blocked command is used on an ephone that has a dedicated park slot, the phone is blocked from parking calls at park slots other than the phone's dedicated park slot but can still park calls at its own dedicated park slot.

Call-Park Redirect

By default, H.323 and SIP calls that use the call-park feature use hairpin call forwarding or transfer to park calls and to pick up calls from park. The call-park system redirect command allows you to specify that these calls should use H.450 or the SIP Refer method of call forwarding or transfer. The no form of the command returns the system to the default behavior.

Call Park Recall Enhancement

Before Cisco Unified CME 9.5, a parked call could not be recalled by or transferred to the phone that put the call in park or the original phone that transferred the call when the destination phone was offhook or ringing.

In Cisco Unified CME 9.5, the recall force keyword is added to the call-park system command in telephony-service configuration mode to allow a user to force the recall or transfer of a parked call to the phone that put the call in park or the phone with the reserved-for number as its primary DN when the destination phone is available to answer the call. For more configuration examples, see the "Configuring Call Park Recall: Example" section.

Park Monitor

In Cisco Unified CME 8.5 and later versions, the park monitor feature allows you to park a call and monitor the status of the parked call until the parked call is retrieved or abandoned. When a Cisco Unified SIP IP Phone 8961, 9951, or 9971 parks a call using the park soft key, the park monitoring feature monitors the status of the parked call. The park monitoring call bubble is not cleared until the parked call gets retrieved or is abandoned by the parkee. This parked call can be retrieved using the same call bubble on the parker's phone to monitor the status of the parked call.

Once a call is parked, Cisco Unified CME sends a SIP NOTIFY message to the parker phone indicating the "parked" event along with the park slot number so that the parker phone can display the park slot number as long as the call remains parked.

When a parked call is retrieved, Cisco Unified CME sends another SIP NOTIFY message to the parker phone indicating the "retrieved" event so that the phone can clear the call bubble. When a parked call is disconnected by the parkee, Cisco Unified CME sends a SIP NOTIFY message to the parker phone indicating the "abandoned" event and the parker phone clears the call bubble upon cancellation of the parked call.

When a parked call is recalled or transferred, Cisco Unified CME sends a SIP NOTIFY message to the parker phone indicating the "forwarded" event so that parker phone can clear the call bubble during park, recall, and transfer. You can also retrieve a parked call from the parker phone by directly selecting the call bubble or pressing the resume soft key on the phone.

How to Configure Call Park

This section contains the following tasks:

Enabling Call Park or Directed Call Park

Verifying Call Park

Troubleshooting Call Park

Enabling Call Park or Directed Call Park

To enable Call Park on SCCP or SIP phones, perform the following steps.

Prerequisites

SIP phones require Cisco Unified CME 7.1 or a later version.

IP phone must support the Park soft key. The Park soft key displays by default on supported SCCP and SIP phones. If previously disabled, you must use the softkeys connected command to enable the Park soft key.

Restrictions

For SIP phones, the Park soft key is not supported for Cisco Unified IP Phone 7905, 7912, 7921, 7940, or 7960.

Park Retrieval is supported only on local phones. Phones can park calls remotely to another Cisco Unified CME router but only phones that are registered to the local router hosting the call-park slots can retrieve a call.

In versions earlier than Cisco Unified CME 7.1, Call Park and Directed Call Park shared the same call-park slots. In Cisco Unified CME 7.1 and later versions, if a user attempts to transfer a call to a basic park slot when using Directed Call Park, Cisco Unified CME considers that a Park Retrieval.

A user can retrieve a parked call on an SCCP phone by pressing the PickUp soft key and dialing the extension number of the call-park slot or an asterisk (*) only if the service directed-pickup command is enabled (default). Otherwise this initiates a local group pickup.

Park Reservation Groups are not supported with Directed Call Park.

Different directory numbers with the same extension number must have the same Call Park configuration.

Calls from H.323 trunks are not supported on SIP phones.

Hold Pickup is not supported with the call-park system application command.

Those extensions can still park calls at the phone's dedicated park slot by using the Park soft key or the Transfer soft key and the FAC for call park.

Where to Go Next

Controlling Use of the Park Soft Key

To block the functioning of the call park (Park) soft key without removing the key display, create and apply an ephone template that contains the features blocked command. For more information, see "Customizing Soft Keys".

To remove the call park (Park) soft key from one or more phones, create and apply an ephone template that contains the appropriate softkeys command. For more information, see "Customizing Soft Keys".

Ephone Templates

The transfer-park blocked command, which blocks transfers to call-park slots, can be included in ephone templates that are applied to individual ephones.

The Park soft key can be removed from the display of one or more phones by including the appropriate softkeys command in an ephone template and applying the template to individual ephones.

For more information, see "Creating Templates".

Feature Access Codes

You can park calls using a feature access code (FAC) instead of a soft key on the phone if standard or custom FACs have been enabled for your system. The call-park FAC is considered a transfer to a call-park slot and therefore is valid only after the Trnsfer soft key (IP phones) or hookflash (analog phones) has been used to initiate a transfer. The following are the standard FACs for call park:

Dedicated park slot—Standard FAC is **6.

Any available park slot—Standard FAC is **6 plus optional park-slot number.

For more information about FACs, see "Customizing Soft Keys".
