Final answer:
A VRU integrates with other technologies like IVR systems to provide automated phone services, improving efficiency in customer service. This integration shows the evolution of technology, like from bulky 1970s computers to modern devices.
Step-by-step explanation:
A VRU (Voice Response Unit) integrates with other technologies to provide automated telephonic services which allow a system to interact with humans through the use of voice and DTMF tones input via a keypad. One example of this integration is in customer service, where VRUs are combined with IVR (Interactive Voice Response) systems to route calls, provide information, and offer services without human intervention. This enhances efficiency and accessibility for businesses engaging with the public or for internal purposes.
Considering technological evolution, it is clear that what seems advanced today may soon become obsolete. The rapid pace of progress ensures that VRUs and IVRs, like those bulky computers of the 1970s, will continually evolve, likely integrating with newer technologies such as artificial intelligence to deliver even more sophisticated capabilities.
