title: channel name in asterisk
body: <p>I'm using Asterisk 11. I have a problem to get channel name when I attempt to call-out.
  Usually, I can get the channel name when the called party picks up his/her phone. But now,  I would like to get the channel name right after I dial out. I can see it on the screen like this:</p>
  
  <pre><code>Called SIP/7146991234@64.195.139.88
  - SIP/64.195.139.88-00000001 is ringing
  -- SIP/64.195.139.88-00000001 is making progress passing it to SIP/8001-00000000
  </code></pre>
  
  <p>I know that the channel name is : "SIP/64.195.139.88-00000001",
  but I don't know how to get it from coding or any other ways.
  Please help me.
  Thank you very much!</p>
