## Click-to-Call widget added

Add one-click voice and video calling to a website or app by embedding the Click-to-Call
widget, with no custom development. The widget uses WebRTC and connects to your existing
SignalWire resources, so a call can reach the PSTN, a SIP endpoint, an AI agent, or a custom
workflow. See [Click-to-Call widget](/docs/browser-sdk/guides/click-to-call-widget).
