This feature is especially useful for users who are constantly on the move or work across different devices. For instance, if a call is answered on a PC and the user needs to leave their desk, they can easily switch the call to their WP or smartphone without hanging up or redialing.

When an incoming call is answered on one device, a notification appears on the screen of the other registered devices, giving the user the option to switch the active call to that device. Once the call is switched, the original device automatically terminates the call session, ensuring that only one device remains active on the call.

Supported Scenarios

• The account is engaged in a 2-way call or a UCM conference.
• The active call can be either audio or video.

Unsupported Scenarios

• The account is handling multiple exclusive calls simultaneously with different users.
• The account is acting as the host of a local conference call, where switching could disrupt the session.

How to Perform a Call Switch

• Method 1: Tap the notification bar at the top of the device LCD when prompted. Please see the screenshot below for an example of the notification bar.

• Method 2: Dial the feature code *46 (or a customized code if configured on the UCM server).

CALL RECORDING

Recording calls is a feature supported by WP856. It can be triggered using the feature code (*3) or it can be done through the graphical user interface, please see the steps below.

1. During a call, tap the three dots on the bottom right of the screen.
2. From the menu, tap “Record”, then the call recording will start.

3. A small tab will appear on the left side of the screen to indicate that the call is being recorded and the duration of the recording.
