Examples

Usage with TelnyxRTC Client .on:

client.on('telnyx.notification', (notification) => {
  if (notification.type === 'callUpdate') {
    console.log(notification.call);

    // Do something with the call and update UI accordingly
  } else if (notification.type === 'userMediaError') {
    console.log(notification.error);

    // Handle the error and update UI accordingly
  }
});

The notification structure is determined by its type.
