title: How To Set up Call Hold and Pick Up In Asterisk
body: <p>I am quit new in asterisk.</p>
  
  <p>My problem is: I have to implement call hold and pick up in asterisk.</p>
  
  <p>Let's say we have an incoming call called incomingCallA.
  As an operator I want to hold incomingCallA for a while to deal with other works, then come back soon, If i am not come back, others operator will pick up my held call. </p>
  
  <p>I have done some researches that told me:
  Call hold is sip client function, dont need to changes at asterisk server.</p>
  
  <p>I can use call parking to dial to others operator if i am not come back.</p>
  
  <p>Please help me to about the solution to deal with above problem.</p>
  
  <p>Many thanks.</p>
