Final answer:
Automatic call distribution systems do allow calls to be routed to voicemail, either when agents are unavailable or as per specific rules set within the system.
Step-by-step explanation:
True, automatic call distribution (ACD) systems do allow calls to be automatically routed to voice mail. ACD is a telephony technology that distributes incoming calls to a specific group of terminals or agents based on customer need, agent availability, and other predefined rules.
In cases where no agent is available, or during non-business hours, the ACD can be programmed to route calls directly to voicemail, ensuring that the caller can leave a message to be addressed later. ACD systems are integral to call centers and businesses that handle a high volume of calls, enabling them to manage resources effectively and improve customer experience.
