Which system answers and routes telephone calls through automated messages?

The system that answers and routes telephone calls through automated messages is indeed the voice messaging systems. These systems are designed to manage incoming calls automatically, providing callers with instructions through pre-recorded messages. This allows callers to select options or leave messages without the need for human intervention.

Voice messaging systems can efficiently handle a large volume of calls, directing callers to the appropriate department or individual based on the responses to their selections. They are widely used in various business environments to enhance efficiency, reduce wait times, and improve customer service.

In contrast, mobile communication refers to the use of mobile devices for voice and data transmission, but it does not inherently include automated call routing. Electronic data interchange is a method for transferring structured data between different organizations, focusing on electronic data transmission rather than call management. Video conferencing facilitates face-to-face communication over the internet but does not involve automated telephone call handling. Thus, voice messaging systems specifically address the question regarding automated call answering and routing.
