Power dialing mode, also called automatic call dialer mode, is an outbound dialing technology that automates the call dialing process. When you use power dialer software to make calls, it picks numbers from a predefined list of contacts/prospects and starts calling them one after the other.An automatic dialer dials a number, connects it to the prospect, and waits for the agent to complete the call before dialing the next contact in the queue. Call dialer tools help agents reduce the time spent on choosing contacts from a list or CRM and manually dialing them.
