If you absolutely have to change the image using code, then you should data bind the Image.Source property and then change your data bound image path:

<StackPanel Orientation="Horizontal">
    <Image Source="{Binding ImageSource}" Height="30" Margin="14,0" />
</StackPanel>

The default value for your new property would be Resources/dial.png and you could change it like so:

ImageSource = "Resources/hangup.png";

Of course, your ImageSource property must notify the INotifyPropertyChanged Interface of the change so that the UI can update the Image. However, it must be said that using a Trigger or DataTrigger to change the Image.Source in XAML would be a better solution.
