No matter how skilled your live agents are, there’s a limit to how many customers they can attend to at once. Some customers will have to wait awhile for their calls to be answered—if they get answered at all. From a customer’s perspective, no one wants to be on hold for a long time. What kind of a customer service experience is sitting to elevator music for 5, 10, 30, 60 minutes? As your business grows, you’ll need effective systems in place to handle high call volumes in a timely manner. That’s where an interactive voice response (IVR) comes in. In some cases, a simple implementation of an IVR is also called a phone tree.
