title: ASP.NET and sending SMS/making phone calls
body: <p>I have a scenario where I need to make a call to a telephone(landline/mobile)  or send SMS to a particular set of users only using ASP.NET and C#. The web application is not a mobile application.</p>
  
  <p>How do I go about doing these? What typically would be the hardware requirements? I would be <strong>extremely grateful</strong> if you could provide me with pointers and reference websites.</p>
