title: Rest : How to identify an action non resource related
body: <p>I would like to use the Rest-Easy framework to develop my application. 
  My application is VOIP (telephony) related.
  It can : </p>
  
  <ul>
  <li>Originate a phone call between two phone numbers</li>
  <li>Transfer a phone call</li>
  <li>Perform CRUD actions on resources</li>
  </ul>
  
  <p>Those phone calls are not saved and thus are not considered as resources in my application. </p>
  
  <p>How should I name the rest url to originate a phone call ? </p>
  
  <ul>
  <li>/originate/numberA,numberB</li>
  <li>/originate/[numberA,numberB]</li>
  <li>/number/numberA/originate/numberB</li>
  <li>other?</li>
  </ul>
  
  <p>Same goes for transfer (where 3 parameters (phone numbers) are required).</p>
