Sometimes you need to dial a number from within a mobile app and for my surprise that functionality was not directly exposed through the Oracle Mobile Application Framework APIs.
Oracle MAF provides a component called Link (Go) available under the General Controls palette that can be used for navigation between pages but it can also be used to enable linking to external URLs.
Using the tel: URL scheme with the Link (Go) component gives you the capability to dial phone numbers from within an Oracle Mobile Application Framework app.
So, here is how to do it:
On your MAF page, drag and drop a Link (Go) to the Panel Page and then set the URL in the component properties to the desired phone number. You can also use a Managed Bean to set the value if you want to do some processing before displaying the number to be called.

If you have mixed UI content on your Oracle MAF app and you want to get the same behavior on a HTML page you just need to add the following on your source code:
<a href="tel:+1-800-555-1234">call this number</a>
