📍 Where to find it: Inboxes → (your Voice inbox) → Call settings tab → Enable calls

Your visitors can call you live from your website's chat widget, in one click, without dialing a number: a "Call now" button starts a voice call right in the browser.

How it works

When calls are enabled, the chat widget shows a "Call now" button on its home page. The visitor clicks, their microphone is connected, and the call rings your online agents like an incoming call. The visitor needs no phone number: everything goes through the browser (WebRTC). The button only appears if your team is online, on a secure page (HTTPS).

Step by step

  1. Enable calls on the inbox that serves your website widget (Call settings tab → "Enable calls").
  2. Make sure your website is on HTTPS (padlock in the browser).
  3. Check that your business hours are set and that at least one agent is "Online".
  4. Reload your website: the "Call now" button appears on the widget's home screen.
  5. Run a test from another device to confirm the sound works both ways.

Good to know

  • The button is hidden automatically if no agent is online, if the site is not on HTTPS, or if calls are not enabled.
  • If you don't see the change, it is often the widget cache on your site (service worker / PWA): clear the cache, it is not a Madyis Hub bug.
  • A call through the widget is still billed by Twilio (≈ 1 cent/minute of conference): it is not entirely free.
  • If a visitor leaves the page mid-call, Madyis Hub ends the call cleanly on the server side.
