One Edesy agent can answer and place calls on several channels: phone numbers (inbound and outbound), a voice widget on your website, a public share link, browser WebRTC calls, and WhatsApp calling. The agent's prompt, tools and post-call processing are the same on every channel, and every call lands in the same call history.

## FAQs

**Do widget and share-link calls cost the same as phone calls?**
They use the same per-minute agent pricing, without telephony charges from a carrier. See [billing](https://edesy.in/docs/voice-agent/billing).

**Can I limit who uses the widget?**
Yes. Widget keys only work on the domains you allow.

**Is WhatsApp calling self-serve?**
Not yet. Talk to us to enable it.
