Capture engagement without the conversation.

Businesses can capture every incoming call's data (including caller number and date & time), disconnect the call instantly, and use those details to power custom business workflows.

Zero-cost capture

The caller is never charged, while your application receives all the data it needs (caller number, timestamp, and session identifiers) in real time.

How the programmable missed call flow works

The dial, the disconnect and your downstream workflow all run on webhooks and the EnableX Voice API.

Core capabilities & benefits

For developers

Developer capabilities

  • Webhook-driven event model: Receive incoming and disconnected call notifications at your own HTTP endpoints.
  • Secure REST APIs: Full call control, including programmatic disconnect.
  • Rich metadata: Caller number, date/time of the call, and more.
  • Dedicated virtual numbers: Configurable numbers for different campaigns, regions, or brands.
For the business

Business benefits

  • Zero-cost interaction: The caller pays nothing, so the barrier to respond is a single dial.
  • Simple opt-in: A call is easier than a form, which is why missed-call flows are widely used in markets where customers prefer a free call to a form.
  • Faster time-to-market: Use a managed CPaaS voice layer instead of custom telecom integrations.
  • Telecom-grade scalability: Built on the proven EnableX Voice Platform.
