Single Button Call Parking is a feature that allows a person to put a call on hold at one telephone set and continue the conversation from any other telephone set.

The “call park” feature is activated by pressing a preprogrammed button (usually labelled “Park”) on a Yealink device. This transfers the current telephone conversation to an unused extension known as a Call Park Orbit and immediately puts the conversation on hold. (This is called parking the call; and the call is said to have parked onto a certain extension. Essentially, call parking temporarily assigns an extension number to an incoming call.) Callers placed into a park orbit will hear Music on Hold until the call is retrieved.

Once a caller has been parked, a BLF line key on the Yealink phone will flash to let other users know that the park orbit is occupied. Any user may retrieve the caller from the park orbit by pressing the BLF line key.



There are two types of call parking orbits supported on the ParagonVoIP system.  This guide covers Directed Call Parking using the BLF DSS Key on a Yealink phone.

  • Directed -  This is the traditional call parking feature where the person that performs the park simply transfers the caller to a Call Park Orbit.  The orbit (also called a queue) must be pre-existing and must be empty in order for the parking attempt to work.
  • Dynamic - In this scenario, the person that performs the park will dial *** and the system will transfer the caller to any available orbit (the parker does not need to know the location of the orbit or if orbit is available or not).   After receiving ***,  the system will announce the orbit location.  

Creating the Call Park Queue

The first step in configuring Call Parking is to create one or more Call Park Orbits.

 Create a Queue

Browse to the Queues page, and select the Add Call Queue button.



 Configure Queue Extension and Type

In the Add a Call Queue screen, enter the following values then click Add:

  1. Name - can be any word that is descriptive of the purpose.
  2. Extension - For Call Park Orbits, the queue extension MUST be between 710 and 729 (Queues in the 720-729 range have Ringback enabled).  This number range is reserved for Directed Call Park Orbits in the system.
  3. Type - Select Call Park from the drop-down box.



Verify Call Park Queue

Confirm that the queue you created is listed in the Queues page.


Set Call Park User to Unlimited Ring Timeout

After the Queue has been created, manage the queue User, and set the "Ring for" to Unlimited.   If this is not set, then parked callers will hear an option to escape the queue at intervals that match the Ring for setting.

Configuring a Call Park Key

The Call Park Key on a Yealink phone may be configured using the device's web UI, or by remotely provisioning the phone using overrides in the ParagonVoIP Provisioning Server (NDP). To have this option open a ticket with detailing the extension and button you would like this feature attached to. 


Using the Web UI

To configure a Call Park key with the web UI, browse to the phone admin page and configure a Line/Memory Key under the 'DSSKey' tab with the following parameters.

Field Name
Call Park
Enter the extension of the Call Park Queue that you created in the previous step.
This is the label that will appear on the phone's display.
This is the line of the phone that will be used to park the call.

Transferring and Retrieving Calls 

Once the queue has been created and a Call Park key has been configured as above, you may park any active call to the queue by pressing the key labeled Park5.  Once placed into the queue, the LED of Line Key 2 will turn red, denoting that a call has been parked.  

To retrieve the call, any user with that Call Park key can touch the key to pickup the call.


Using DSS Keys to Park Calls 


Other Ways to Park a Call


In cases where the DSS Keys are needed for attended transfer, calls can be parked manually by following these steps:

  1. Answer incoming call. 
  2. While on the call, dial *+[Park Queue Extension](e.g. *701).
  3. To retrieve the call, dial *55+[Park Queue Extension](e.g.*55701).
