Prompting for a PIN to be entered using the keypad, then waiting for the user to finish entering the PIN before proceeding with the next instructions.

import { SignalWire } from "@signalwire/realtime-api";

const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" })


const call = await client.voice.dialPhone({
  from: "+YYYYYYYYYY",
  to: "+XXXXXXXXXX",
});

// Prompt for digits
await call.promptTTS({
  text: "Please enter your PIN",
  digits: {
    max: 5,
    digitTimeout: 5,
    terminators: "#*",
  },
  listen: {
    onStarted: () => console.log("Prompt started"),
    onUpdated: (event) => console.log("Prompt updated", event.result),
    onEnded: async (event) => {
      console.log("Prompt ended", event.result);
      console.log("Users Pin", event.digits);
      call.hangup();
    },
    onFailed: () => console.log("Prompt failed"),
  }

  digits: {
    max: 5,
    digitTimeout: 2,
    terminators: "#*",
  },
});
await prompt.setVolume(-20);
