Live demo · we call you

Text us. We call you back on WhatsApp.

Send us a message and your phone rings within seconds — a real WhatsApp call, placed by software. Say something after the beep and you will hear your own voice come straight back.

or call it yourself —

We call only the number that messaged us, we do not read what you wrote, and the five seconds you record are deleted the moment they have played back.

Audio sequence

What you'll hear

About thirty seconds, start to finish. Nothing is queued, scheduled or replayed: the call is placed when your message arrives.

  1. 1 0:00

    You send a message to the number. Anything at all.

  2. 2 0:03

    Your phone rings — a WhatsApp call, placed by software.

  3. 3 0:05

    A greeting: where you are and what happens next.

  4. 4 0:17

    A beep. Say something; five seconds are recorded.

  5. 5 0:22

    You hear your own voice, back through the same call.

  6. 6 0:30

    Goodbye, and the call ends.

Why it matters

What the demo proves

A real WhatsApp call

Placed from an ordinary WhatsApp number to yours. Not the Meta Business API, no template, no business verification.

a regular WhatsApp number

Placed by software, outbound

Your message arrives, and code decides to ring you. That is the direction an agent needs and the hard one to build.

message in → call out

Audio both ways

What you hear after the beep is your own voice, recorded a moment earlier and sent back over the same call.

you speak → you hear it back

Topology

The path your call takes

One message in, one WhatsApp call out — a few seconds apart.

  1. You send a WhatsApp message to the demo number.
  2. WhatsMCP sees your message.
  3. WhatsMCP calls you back on WhatsApp, and your phone rings.
Constraints

Honest limits

A public demo on a real WhatsApp number, so it is fenced in. Each of these is enforced in code rather than promised.

  • One call at a time — the demo is a single line.
  • Forty-five seconds, then it hangs up on itself.
  • Three answered calls per number per day, sixty across everyone.
  • One call per number per ten minutes, however many times you write.
  • We call only the number that messaged us. There is no field to type someone else’s.
  • We do not read your message. Any message is the request.
  • Your five seconds are deleted as soon as they have played back.
  • No keypad menus yet.

The same path your own numbers get.
