Added in 2026.6 Click To Call lets you create a voice AI Agent that end users can talk to with a single click. You can deploy Click To Call through the following options:
  • Click To Call Widget — you can easily embed a widget into your website. Additionally, you can use the Click To Call Widget API and CSS styles to customize your AI Agent.
  • Click To Call SDK — you can build a custom application using the Click To Call SDK.

Key Benefits

  • Optimized latency and high definition audio quality. The underlying web real-time communication (WebRTC) protocol and Opus codec allow for low-latency and higher quality audio communication.
  • Multimodal communication. Users can communicate primarily through voice with the AI Agent, but you can extend the capabilities of your voice AI Agents with event handling and API methods.
  • Centralized entry point. Users can access your voice AI Agent directly through the widget while browsing through your website without the need to call a phone number.
  • Swift voice communication. Users can start a conversation with your voice AI Agent with just one click.
  • Transfer calls. The Click To Call widget supports Dial call transfers. This way, you can transfer the call to a human agent or a contact center.
  • Fully customizable. You can customize the Click To Call widget with the CSS styles in the Click To Call widget GitHub repository to match your brand or build a custom application using the Click To Call SDK.
