Typically, when you place a call on hold, you can retrieve the call only from the original phone where you placed the call on hold. Shared-line systems bend the rules by allowing you to retrieve the call from any phone with the same shared line assignment.
The call park feature takes this one step further by allowing you to retrieve the call from any phone in the organization. Call park “parks” the caller on hold at an extension rather than on a specific line. Any IP phone that is able to dial the park extension number can retrieve the call.
The call park system works by finding free Directory numbers in the CUCM configuration that you have not assigned to an IP phone and have specifically designated as a call park slot.
Scenarios fits different environments. Calls being parked at random extensions might work well for a warehouse environment with a voice-paging system. When an employee has a call, the receptionist could announce, “Josmo, you have a call on 5913,” over the loudspeaker, at which point Josmo could go to a phone and dial the extension to pick up the call on hold.
To park a call, simply press the Park softkey while on an active call. CUCM finds a parking slot for the call and send a message back to the phone that parked the call.
When the user parks the call, CUCM/CME allocates the first available park slot. Sometimes, you might want to designate which parking slot the call gets, in cases such as those in which each department of the company is assigned a unique call park number. In this case, you can transfer the call (using the Trnsfer softkey) directly into the parking slot you want.
You can answer parked calls in one of three ways:
■ Dial directly into the call park slot. For example, lifting a phone handset and dialing 1095 answers whatever call is parked at 1095.
■ Press the PickUp softkey and dial the call park number that you want to answer.
■ From the phone at which the call was parked, press the PickUp softkey followed by an asterisk (*) to recall the most recently parked call back to the phone.
In this demonstration, MOKAJOS (1004) calls JOSMO (1003) who receives the call. Then JOSMO parks the call by pressing the Park softkey and then he receive a confirmation message that the call has been parked at 1095.
Step 1: MOKAJOS (1004) calls JOSMO (1003) who receives the call as shown below.
Step 2: Then JOSMO (1003) parks the call by pressing the Park softkey and then he receive a confirmation message that the call has been parked at 1095 as shown in the figure below.
Step 3: JOSECK (1000) who want to retrieve the call can just call the park Directory of 1095 to retrieve the call as shown in the figure below.
