Record a call

A code snippets that shows how to answer an incoming call and set it up to record, then connect the call. When the call is completed, the eventUrl you specify in the record action of the NCCO will receive a webhook including the URL of the recording for download.

Example

Replace the following variables in the example code:

KeyDescription
VONAGE_VIRTUAL_NUMBER

Your Vonage Number. E.g. 447700900000

VOICE_TO_NUMBER

The recipient number to call, e.g. 447700900002.

Prerequisites

Write the code

Add the following to record-a-call.js:

const Express = require('express');
const bodyParser = require('body-parser');

const app = new Express();
app.use(bodyParser.json());

const onInboundCall = (request, response) => {
  const ncco = [
    {
      action: 'record',
      eventUrl: [`${request.protocol}://${request.get('host')}/webhooks/recordings`],
    },
    {
      action: 'connect',
      from: VONAGE_VIRTUAL_NUMBER,
      endpoint: [
        {
          type: 'phone',
          number: VOICE_TO_NUMBER,
        },
      ],
    },
  ];
  response.json(ncco);
};

const onRecording = (request, response) => {
  const recording_url = request.body.recording_url;
  console.log(`Recording URL = ${recording_url}`);

  response.status(204).send();
};

app
  .get('/webhooks/answer', onInboundCall)
  .post('/webhooks/recordings', onRecording);

app.listen(port, () => {
  console.log(`Example app listening on port ${port}`);
});
