title: VoIP Integration in App & Web
body: <p>I have a very general question on how to implement VoIP for our current mobile &amp; Web App. (we have an Android+iOS App and a Web Application based on AngularJS/NodeJS).</p>
  
  <p><strong>What we want to achieve</strong></p>
  
  <p>In the first step we want to achieve inter Application Voice and Video Calls. Later on we <strong>might</strong> expand into outbound calls into the normal telephone network. But this post is mainly for getting info on how to implement only our first step.</p>
  
  <p><strong>general thoughts</strong></p>
  
  <p>We had some experiences with Asterisk before which turned out to be far from easy. So for this project we wanted to get some feedback before actually implementing anything.</p>
  
  <p><strong>thoughts on technology</strong></p>
  
  <p>At first I thought it might be a good idea to use <strong>WebRTC</strong>, but since it's only supported on Chrome, FF and Opera for the moment and pretty much is unsupported for native mobile Apps we think that WebRTC is probably out of the picture for now. (or do you think otherwise?)
  After searching the web a bit more we found this: <a href="http://www.webrtc.org/native-code" rel="noreferrer">http://www.webrtc.org/native-code</a></p>
  
  <p>Has anyone experience with this libs? It seems to us, that this could be the best solution for a modern voip solution (and also would allow us to skip the asterisk server)</p>
  
  <p>The second idea would be to setup an <strong>Asterisk</strong> Server for ourselves. Every time a user logs into the App we would connect him as a SIP Client to the asterisk. If one user calls the other one we think we should be able to make the call for example with the node package Asterisk Manager API (<a href="https://github.com/pipobscure/NodeJS-AsteriskManager" rel="noreferrer">https://github.com/pipobscure/NodeJS-AsteriskManager</a>). </p>
  
  <p>The third idea would be to use a <strong>SIP Provider</strong>, but at the moment I'm not sure if that's really the best idea.</p>
  
  <p>Since we're no VoIP experts, are there any other possibilities for VoIP integration into our apps?</p>
  
  <p>Any thoughts on that subject would be very appreciated! Thank you!</p>
