Click-to-call
（重定向自Click to talk）
Click-to-call, also known as click-to-talk, click-to-dial, click-to-chat and click-to-text, is a form of Web-based communication in which a person clicks an object (e.g., button, image or text) to request an immediate connection with another person in real-time either by phone call, Voice-over-Internet-Protocol (VoIP), or text. Click to talk requests are most commonly made on websites but can also be initiated by hyperlinks placed in email, blogs, wikis, flash animations or video, and other Internet-based object or user interfaces.
