What is a callback?

A callback is any executable code sent as a reply to another program, expecting that the other program will call back the argument at a predetermined time. This execution can occur right away, as in a synchronous callback, or it can take place later, as in an asynchronous callback.

A security feature calls the dialed-in user back to confirm that they are who they claim they are. They are permitted access after the callback and verify the username, password, and any other information.

There are two kinds of callbacks. Each controlling data flow differently during runtime:

  • Blocking callbacks (also known as synchronous callbacks or just callbacks) 
  • Deferred callbacks (also known as asynchronous callbacks)

Importance of callback in call centers

Your clients will not have to wait in long lines if you use Callback software. They will instead wait for an agent to call them. Customers will appreciate you even more if they are used to callbacks.

Further, your call center’s callback feature ensures that you connect with each caller, even if they cannot reach you the first time. As a result, it will lower abandonment rates, improve the success of your contact center, and raise your earnings.
