Idea of launching Call Task from Secondary Tiles is very simple.

  1. On clicking of Secondary Tile user will get navigated to a blank page. Let us call that page as Page1.XAML
  2. On NavigatedTo method of the Page1.Xaml, we will instantiate Call Task and show call panel to user.

Let us create Secondary Tile on MainPage.Xaml. I have put a button on MainPage and on click event of the button Secondary Tile will get created.

private void btnCreateSecondaryTiles_Click(object sender, RoutedEventArgs e)

var newTile = new StandardTileData()
Title = "Blogs Update",
BackgroundImage = new Uri("background.png", UriKind.Relative),
Count = 42,
var uri = "/Page1.xaml?state=Live Tile";
ShellTile.Create(new Uri(uri, UriKind.Relative), newTile);


If you notice in above code, I have set navigation to Page1.Xaml. Now on onNavigatedTo() method we need to write code to launch Call Task.

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
PhoneCallTask callTask = new PhoneCallTask();
callTask.PhoneNumber = "999999";
callTask.DisplayName = "debugMode";



On running you should be getting below output


I hope this post was useful. Thanks for reading.

  2. hello.

    it is valid that after launching the PhoneTask, the app navigates to the Home Screen so that when the user is done with the PhoneTask, he/she lands in the Home Screen instead of in a page of the app.
    (something like using the secondary tile as a direct access to the PhoneTask).


    p.s.: sorry if my english is not very good.

  3. Nice post .

    I would also like to add a point to the post .

    Currently “You Cannot dial service codes programmatically”… For example “*43#” cannot be dialed programatically …
