UWP URI for making a call
<p>I'm working on a UWP app that uses a RichTextBlock to display some text that the user can enter, I want it to Identify phone numbers so that I can tap the number and then the application should take me to the call app or people app and give me the option to call this number. I search for a solution for that and what I found so far is in this link:
<a href="https://msdn.microsoft.com/en-us/windows/uwp/launch-resume/launch-default-app" rel="nofollow">https://msdn.microsoft.com/en-us/windows/uwp/launch-resume/launch-default-app</a></p>

<p>I couldn't find the URI that I can use to make it work, the best thing that I've achieved so far is by using a hyperlink that contains the following:</p>

<pre><code> if(isPhoneNumber)
       hyper = @"ms-people:savetocontact?PhoneNumber="+hyper+"&amp;Email=&amp;ContactName=";
</code></pre>

<p>but now when I tap the number the people app is launched on the contacts list screen. </p>

<p>Any advice would be great, thanks.</p>
