Automatic Call Distribution (ACD) is a telephony system that manages incoming calls by routing them to the appropriate agents or departments. It uses predefined rules to ensure that calls are directed based on factors like agent availability, skill set, or caller needs, improving efficiency and customer satisfaction. ACD systems are commonly used in call centers to handle high volumes of calls. They can provide features such as call queuing, prioritization, and reporting, allowing businesses to monitor performance and optimize their operations. This technology helps streamline communication and enhances the overall customer experience.
