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”) or a sequence of buttons (for SkySwitch this sequence is usually *701, but see below for details) . 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.) The telephone system will then announce the extension of the parked call so that the call can later be retrieved.
At this point, person that parked the call can make an announcement (often by paging some or all of the telephone sets and or overhead paging speakers controlled by the telephone system). An example would be at a grocery store where the bakery has a call parked. The user would say "Bakery you have a call parked on 627" and the bakery department would then dial 627 to access the call on hold.
A set time is then provided for any person to retrieve the call by dialing the extension number of the parked call on any telephone set.
There are two types of call parking orbits supported on the SkySwitch system.
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.
The first step in configuring Call Parking is to create one or more Call Park Orbits.
Browse to the Queues page, and select the Add Call Queue button.
In the Add a Call Queue screen, enter the following values then click Add:
Confirm that the queue you created is listed in the Queues page.
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 escapte the queue at intervals that match the Ring for setting.
Once the queue has been created you may transfer any caller to the queue by doing the following:
Once placed into the queue, the caller will hear the music on hold file that is associated with the queue owner (702 in the example above). If the queue owner does not have Music on Hold, then the caller will hear the system's default music on hold.
In many cases, it is desirable to program a button on a phone so that a caller may be parked by touching the button and so that the button will display the status a Call Park Orbit. Capabilities for Single Button Call Parking will depend on the type of phone.
Configuring a Call Park status key that will show the current state of a Call Park Orbit, and will allow the user to retrieve the parked call by pressing the key.
Configuring the Call Park watch key on a Polycom requires the following over-rides in the NDP:
attendant.reg="1" attendant.behaviors.display.spontaneousCallAppearances.automata="Automatic" attendant.behaviors.display.remoteCallerID.normal="Normal" attendant.resourceList.1.address="701" attendant.resourceList.1.label="Park" attendant.resourceList.1.proceedingIsRecipent="1" attendant.resourceList.1.type="automata" feature.1.name="presence" feature.1.enabled="1"
Configuring single button call parking on a Polycom phone requires the following over-rides in the NDP.
softkey.1.enable="1" softkey.1.use.active="1" softkey.1.label="Park" softkey.1.insert="4" softkey.1.action="702$Trefer$"
Setting these paramters will add a Softkey button to the Polycom LCD:
Configuration of other phones is betond the scope of this guide. However, as a general rule, if the phone can be configured to show the presence of another extension, then it will be able to display the status (occupied/empty) of a Call Park orbit.
