Click-to-dial, otherwise known as click-to-call, is a means of outbound dialing that requires agents to manually “click” to initiate every single call. In a click-to-dial mode, a system is not capable of automatically dialing leads. 

TCPA compliance is the adherence to the statutes of the Telephone Consumer Protection Act (TCPA), the predominant federal law regulating telemarketing calls, auto-dialed calls, prerecorded calls, text messages, and unsolicited faxes. The TCPA prohibits a wide range of call center and telemarketing activities, including the use of an automatic telephone dialing system (ATDS) to contact cell phones unless the recipient has provided and not revoked consent to receive that call or text. Organizations that may be dialing leads without express-written consent may wish to use a click-to-dial system in order to support TCPA compliance.
