Call Park

The Call Park service, first introduced in Lync Server 2010, enables users to place a call on hold and then pick up that same call at another location or extension. To enable a call park, administrators must first configure a call park orbit table or a group of extensions to be used for parking calls. As users park calls, an extension is randomly selected from these orbit tables and assigned to the call.

To create a new range for parking calls, follow these steps:

1. Open the Lync Server 2013 Control Panel.

2. Click Voice Features.

3. Click Call Park.

4. Click New to create a new number range.

5. Enter a descriptive Name for the range.

6. Enter a beginning and ending number for the Number Range. The range can use up to nine total digits and can begin with a # or * so as not to overlap with existing extensions.

7. Select a FQDN of Destination Server from the selection box. Calls parked to the specified extension range are handled by the specified Front End pool.

Alternatively, the Lync Server Management Shell can be used to configure a new call park orbit through the New-CsCallParkOrbit cmdlet.

Configuration of the following additional call park settings can be performed only in the Lync Server Management Shell through the Set-CsCpsConfiguration cmdlet:

• CallPickupTimeoutThreshold—The amount of time a call that has been parked waits without answer before it rings back to the endpoint that originally answered. This is to ensure that a call is not parked and then forgotten.

• EnableMusicOnHold—A true or false value that determines whether on-hold music is played to the caller while parked.

• MaxCallPickupAttempts—The number of times a call rings back to the phone that originally answered before it times out and is forwarded to a specified SIP URI.

• OnTimeoutURI—A SIP URI where calls that are not picked up are forwarded. This is typically an operator or a main line.
