title: How to make an internet call on phone from Android on a tablet
body: <p>I am working on a custom embeded security system build on a Nexus 7 tablet. I would like to be able to automatically call my cell phone (later the 9-11) from my application. I don't know if it is possible. My guess is, that it is in theory.</p>
  
  <p>So, anyone have an idea on how to make an internet call from Android program on a tablet?
  Would it be complicated?
  Is there a webservice I could use?</p>
