title: No audio on Asterisk SIP call
body: <p>I almost managed to init a 2 sided call (click to call): 1st to my office and the 2nd to my cell using Michal Niklas answer (thanks Michal) on 
  <a href="https://stackoverflow.com/questions/4194977/asterisk-click-to-call">Asterisk click to call</a>.</p>
  
  <p>The major ISSUE is that the 2 call participants can not hear one each other, I used from-internal context for both of them. The system status web UI shows me 4 active channels and 2 external calls when the call is connected with both sides.</p>
  
  <p>I configured the
  Channel: local/MY OFFICE PHONE@from-internal
  Extension: MY CELL PHONE</p>
  
  <p>when I set the Channel to Sip/1 and check it with soft phone it works great!</p>
  
  <p>Thanks for helping...</p>
