What does Interactive Voice Response mean

IVR - short for Interactive Voice Response - is a technology that automates interactions with telephone callers. It makes communication able between computers and phones. The most common way for a phone to communicate with a computer is through the tones generated by each key on the telephone keypad. These are known as dual-tone multi-frequency (DTMF) signals. More advanced IVR systems include speech-recognition software that allows a caller to communicate with a computer using simple voice commands.

IVR (Figure 1) allows customers to interact with a companys host system via a telephone keypad or by speech recognition, after which they can service their own inquiries by following the IVR dialogue.

The use of IVR and voice automation enables a company to improve its customer service and lower its costs. Because of the process being automatic, there is no need to hire call center staff (which can lower the costs), although advanced IVR systems have the possibility of forwarding calls to human operators. In case the caller does not find the information they need, or requires further assistance, the call can then be transferred to an agent.

IVR platforms are the "server and operating system" hardware and software platforms on which IVR solutions run. IVR applications are programs that control and respond to calls on the IVR platform. IVR applications can either be developed by an enterprise, by an IVR development shop, or by companies that offer canned IVR applications. With Ozeki VoIP SIP SDK you can develop the best IVR solution fitting to your company's needs.
