Call Park and Directed Call Park services are used to store a call on a specific number so that any other user on the system can retrieve it. For example, a user receives a call but wants to take it in a conference room where it is possible to speak privately. Transferring the call to the conference room is not an option because the conference room it is transferred to might be in use, or the user is unable to walk to the conference room in time to answer the call. The user can use Call Park or Directed Call Park services to place the call at a specific number and then retrieve when they reach the conference room.
To use the Call Park or the Directed Call Park features, at least one Call Park extension should be created in the Extensions Management table. Additionally, two lists should be defined for the call park extension: Park Access List for users that might park a call to the corresponding Call Park extension and Retrieve Access List for the users that can pick up calls parked to that extension. By default, both of these lists have entries so any PBX extension on the QX200 can park the call, and any PBX destination can retrieve the parked call. Any limitations to these settings should be done individually for each call park extension.
To make a Call Park, the QX200 user which has been previously added to the Park Access List for at least one of the available Call Park extension on the QX200 should dial the appropriate digit combination (see Feature Codes) during the call. The active call will go on hold, while the PBX number and the SIP username (if it is registered on the SIP server) of the first available call park extension where the user is added will be played to him/her.
The pickup user will be able to pick up the parked call from any destination by calling the extension where the call has been parked (either by its PBX number or SIP address). The authentication password will be prompted (if configured) of the call park extension in order to retrieve the parked call.
For example, the Call Park extension 77 is created which has been registered on the SIP Server under the 892220 registration username. The QX200 user is added to the Park Access List, while the phone at the remote location is added to the Park Access List of that call park extension.
While being on a call with user A, the QX200 user dials the appropriate calling code. As a reply, QX200 will play the extension 77 and SIP username 892220 to the QX200 user. The user A goes on hold. The QX200 user moves to a remote location and makes a call to the call park extension. The QX200 user enters call park extension's password and resumes the conversation with user A.
To make a Directed Call Park, the QX200 user, which has been previously added to the Park Access List for at least one of the available Call Park extension on the QX200, should place the current call on hold and then dial the Call Park extension number within 5 seconds (see Feature Codes).
Attention: If this timeout exceeds 5 seconds, then QX200 will consider it as an attempt for retrieving the parked call.
Attention: The Call Park extensions can be mapped directly to the programmable keys on IP phones. Using the programmable key configuration calls can be easily parked by placing the current call on hold and then pressing the park extension button. The call will be automatically parked to that Call Park extension.Pressing the park extension button again will retrieve the parked call.
The pickup user will be able to pick up the parked call from any destination by calling the Call Park extension where the call has been parked (either by its PBX number or SIP address). The authentication password will be prompted (if configured) of the Call Park extension in order to retrieve the parked call.
Please Note: The Call Parking is valid for the period defined in the Call Park Extension Settings. By default it is 15 minutes. During that time hold music (if configured) will be played to the parked party. When the Retrieve Timeout expires, the phone that initiated the call parking will start to ring. If no one picks up the parked call, or if the phone is off hook, the parked call will be automatically disconnected.
Please Note: Anyone out of the Retrieve Access List who wishes to retrieve the parked call will be requested to pass a password authentication (if the password is defined for the call park extension) to resume the parked call. The parked call will be disconnected if an incorrect password has been inserted and authentication has been rejected.
