title: Best way to retrieve active calls without making request each second?
body: <p>We need to create a monitor that will show any income calls in our extranet in live time.</p>
  
  <p>We were able to show active calls by using <code>/account/~/extension/~/active-calls</code>, however, to achieve what we need we would need to make a request each second which I guess will be blocked by rate limits.</p>
  
  <p>Is there a better solution for it?</p>
  
  <p>Thanks</p>
