title: voip integration in asp.net
body: <p>I have an asp.net web page with a "dial" button; when the user presses the button, it connects the user to the PTSN network to make a phone call. This is for outbound calling only so there's no need to worry about incoming calls.</p>
  
  <p>I'm thinking of using a webphone and finding a VOIP wholesale provider. Ideally, I'd like the server that's hosting the web app to not be involved in this process (ie. the webphone connects directly to the VOIP provider).</p>
  
  <p>What are some of the pitfalls to avoid?</p>
  
  <p>Thanks for your suggestions.</p>
