Application Scenarios
Enhanced Call Park
Enhanced Call Park improves the traditional call park experience by replacing manual Feature Access Code (FAC) dialing with dedicated Park and Retrieve soft keys on Grandstream IP phones.
When integrated with PortSIP PBX, Enhanced Call Park provides:
One-touch call parking and retrieval
Visual notifications for parked calls
Seamless interaction with PortSIP’s advanced call park features
Call Park
The Call Park service allows users to temporarily place a call on hold and retrieve it later from the same extension or a different extension.
Typical use case: You are on an active call and need to move to another location. You park the call and retrieve it once you reach your destination.
Group Call Park
Group Call Park introduces a hunting mechanism that parks a call against an available member of a configured Call Park group, rather than only the user who initiated the park.
Typical use case: If you and your colleagues belong to the same Call Park group, a parked call may be placed on a colleague’s line. That colleague can retrieve the call, handle it directly, or transfer it back to you.
Call Park Notification
Call Park Notification provides a visual alert on the IP phone when a call is parked for a user.
The phone displays an on-screen notification
Indicators or keys light up
The user can retrieve the call by pressing the corresponding button
This eliminates the need to manually dial retrieval codes.
Retrieve Park
A parked call can be retrieved by dialing the Call Park Retrieve Feature Access Code, followed by the extension number where the call is parked.
Typical use cases:
Retrieve a call parked on your own extension
Retrieve a call parked on a colleague’s extension, then transfer the call or notify them
Note: When Enhanced Call Park is enabled, retrieval is typically performed using a dedicated soft key rather than dialing a FAC.
Recall
The Recall feature ensures that parked calls are not left unanswered indefinitely.
You can configure:
The recall destination (the parking user or a specified number)
The recall timer
If a parked call is not retrieved within the configured time, the PBX automatically recalls the call to the defined destination.
Example: If the recall timer is set to 30 seconds and no one retrieves the parked call within that time, the PBX recalls the call to the original parking user (or the configured recall destination).
Parking a Call
If James wants to park a call for his colleague whose extension number is 103, he can do so using the Call Park key—without dialing any Feature Access Codes (FACs).
Steps
While on an active call, James presses the Call Park key.
When prompted, he enters the destination extension number (
103).James presses the Park key to confirm.
The IP phone parks the call on extension 103.
Group Call Park
Group Call Park allows a user to park a call to a Call Park group, making the call available for retrieval by any member of that group.
Configure a Call Park Group
Sign in to the PortSIP PBX Web Portal as the Tenant Admin.
Navigate to Advanced Services > Call Park.
Follow the configuration guide to create a Call Park group.
Example configuration: Extensions 1001, 1002, 1003, 1004, and 1005 are members of the same Call Park group.
Park a Call to the Group
In this example:
James has extension 1003
James is on an active call with extension 1004
To park the call to the Call Park group:
While on the active call, James presses the Call Park key on his IP phone.
As shown on the IP phone screen in the screenshot below, James then presses the GPark key.
The IP phone parks the call to the Call Park group automatically.
Call behavior
The call is parked using the group hunting logic.
All members of the Call Park group receive a parked-call alert notification.
Any group member can retrieve the parked call using their device’s parked-call button or retrieval method.
Result: James does not need to remember or dial any Feature Access Codes (FACs). Group call parking is completed using on-screen keys, providing a faster and more user-friendly experience.
Retrieve a Parked Call
In this example, Alice is on a call with Bob. Bob parks the call on James’s extension (1003).
Visual notification
On James’s IP phone, a Retrieve label is displayed on the screen (as shown in the screenshot below), indicating that a call has been parked on his extension.
Retrieve the call
James presses the RetrievePark soft key on his IP phone.
The call is immediately connected to James.
Result: James retrieves the parked call with a single key press and does not need to remember or dial any Feature Access Codes (FACs).
