The concept of click-to-call, or click-to-talk, is a form of digital communication in which a person clicks on a button or a text to communicate with a person in real-time. These links can happen through a telephone call, SMS or Voice-over-Internet (VoIP) Protocol. The ties that are commonly found on websites can be used as buttons. But often, click-to-call can be initiated by hyperlinks over emails and videos.
