title: Twilio Web Client Multi Line Call
body: <p>I have a Twilio softphone that I am implementing and the basics functions are working great.
  Please I would need to know how to implement a multi line call feature.</p>
  
  <p>I would like to allow a agent in my browser softphone to put a call on hold and dial a different number then resume any call on hold when needed.</p>
  
  <p>I actually have <a href="https://i.stack.imgur.com/Ka7xr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ka7xr.png" alt="Line button image"></a></p>
  
  <p>Thank You</p>
