Call abandonment refers to the act of ending a telephone call before it is completed or before reaching its intended destination. This can occur for various reasons, such as the caller becoming frustrated with long wait times or automated systems, or simply losing interest in the conversation. Call abandonment can also refer to the practice of intentionally disconnecting a call in order to avoid speaking with a particular person or organization. In the business world, call abandonment is often used as a metric to measure customer satisfaction and the effectiveness of call centers.
