An auto-dialer is a technology that automatically dials telephone numbers and connects the call to a pre-recorded message or a live person. Businesses often use auto-dialers for telemarketing, customer service, or emergency notifications. This system can save time and increase efficiency by handling large volumes of calls quickly. There are different types of auto-dialers, including predictive dialers, which use algorithms to determine the best time to call, and preview dialers, which allow agents to review information before dialing. While auto-dialers can enhance communication, they are also subject to regulations to protect consumers from unwanted calls.
