Click-to-Call (click-2-call, click-to-dial, click-to-call-out, click-to call-in, call-me-now, etc.) is a feature that is unique to VoIP. Click2Call uses a hyperlink that sends a command to initiate two phone calls at once—one to the VoIP subscriber’s phone, and the other to an outbound number, usually a customer. A click to call widget can be used by either the VoIP subscriber or a by potential or existing client visiting a web site.
