CallControl.RedialRequested | redialrequested event

Occurs when the device receives a request to redial.


function onRedialRequested(eventArgs) { /* Your code */ }

Event information

Delegate RedialRequestedEventHandler


This class provides access to events that can be monitored and used for modifying the behavior of your telephony-aware app. The following JavaScript code snippet shows how to add event listeners to the CallControl class, and then to respond to one of the events, RedialRequested.

// Define the user-defined valriables
var callControls = null;
var audioTag;

// Add code to initialize your user-defined variables as needed
<code goes here>

// Initialize the telephony device
    function initDevice() {
        if (!callControls) {
            try {
                callControls = Windows.Media.Devices.CallControl.getDefault();

                if (callControls) {
                    // Add the event listener to listen for the various button presses
                    callControls.addEventListener("answerrequested", answerButton, false);
                    callControls.addEventListener("hanguprequested", hangupButton, false);
                    callControls.addEventListener("audiotransferrequested", audiotransferButton, false);
                    callControls.addEventListener("redialrequested", redialButton, false);
                    callControls.addEventListener("dialrequested", dialButton, false);

                    sdkSample.displayStatus("Call Controls Initialized");
                    id("scenario1Ring").disabled = false;
                } else {
                    sdkSample.displayError("No Bluetooth device detected.");
            catch (e) {                
                sdkSample.displayError("No Bluetooth device detected.");

// Event handler code to respond to the RedialRequested event
    function redialButton(redialRequestedEventArgs) {
        // Handle the redial request here.  Indicate to the device that the request was handled.
        sdkSample.displayStatus("Redial requested");
        redialRequestedEventArgs.handled = true;
