Businesses of all kinds use IVR systems to handle large volumes of incoming and/or outgoing phone calls. By automating the process of collecting caller information, performing customer service actions, providing answers to common questions, and routing calls, IVR systems reduce the work involved in making or receiving phone calls.
Also, because IVR phone systems can be programmed to route calls based on predefined rules, they can make call routing more efficient than it would otherwise be.
