summary: >-
  Zoom Phone's client-side surface is Smart Embed — a hosted, prebuilt softphone that a
  third-party web app embeds as an iframe (or loads through a floating-widget script) and
  drives entirely over window.postMessage. It is a hosted UI surface, not a component library:
  there is no npm package, no web components, and no design system. The second client-side
  surface is a set of URI schemes for launching calls and SMS from any external UI into the
  installed Zoom desktop/mobile client.

  security: >-
    The host app MUST validate event.origin on every postMessage; Smart Embed is the only
    Zoom Phone surface where the browser holds the session.
- family: URI schemes (click-to-dial / click-to-SMS)
  kind: uri-launch
  docs: https://developers.zoom.us/docs/phone/outbound-call/
  schemes: [callto, tel, zoomphonecall, zoomphonesms]
  note: >-
    Launches the installed Zoom client with a target number and optional caller-ID parameter.
    No embedded UI, no session in the host page — the lightest possible CTI integration.
- family: Contact Center Smart Embed
  kind: hosted-iframe
  docs: https://developers.zoom.us/docs/contact-center/smart-embed/
  note: >-
    Sibling surface for Zoom Contact Center rather than Zoom Phone; listed because blended
    Phone + Contact Center desktops chain the two.
