1) Interactive voice response (IVR) systems allow customers to interact with an automated phone system through voice commands or keypad inputs to get information or complete tasks without speaking to a human agent. 2) IVR systems map out call workflows with menus, prompts, and options that guide callers to the right department or resolution. Implementing an IVR can improve customer service, provide 24/7 access, increase personalization, boost profits by improving efficiency, and reduce errors. 3) Businesses should consider if their call volume warrants an IVR for call routing. An IVR may be beneficial for customer service, sales, and surveys in addition to routing calls.
