#### Returns

`Promise`\<[`CallPrompt`][callprompt]>

A promise that resolves to a [`CallPrompt`][callprompt] object that you can use to
view the current state and results of the `prompt` session.

#### Examples

**Digits Example**

In this example, we dial a phone number and prompt for `digits` while playing audio in the background.
After the digits are entered or a timeout occurs, the prompt session will end and return the digits results,
and the call will hangup.

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

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

const voiceClient = client.voice;

// Listen for incoming calls
await voiceClient.listen({
  topics: ["office"],
  onCallReceived: async (call) => {
    console.log("Call received");
    // Answer the call
    call.answer();
    // Play audio on the call while prompting for digits. After the digits are entered or a timeout occurs, the prompt session will end and return the digits results, and the call will hangup.
    await call.promptAudio({
      url: "https://cdn.signalwire.com/default-music/welcome.mp3",
      digits: {
        max: 4,
        digitTimeout: 10,
        terminators: "#*"
      },
      listen: {
        onStarted: () => console.log("Prompt started!"),
        onFailed: () => console.log("Prompt failed!"),
        onUpdated: (promptResult) => console.log("Prompt updated!", promptResult.result),
        onEnded: (promptResult) => {
          console.log("Prompt ended!", promptResult.result);
          call.hangup();
        }
      }
    }).onStarted();
  }
});
```

**Speech Example**

In this example, we dial a phone number and prompt for `speech` while playing audio in the background.
After the digits are entered or a timeout occurs, the prompt session will end and return the digits results,
and the call will hangup.

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

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

const voiceClient = client.voice;

// Listen for incoming calls
await voiceClient.listen({
  topics: ["office"],
  onCallReceived: async (call) => {
    console.log("Call received");
    // Answer the call
    call.answer();
    // Play TTS on the call
    await call.promptAudio({
      url: "https://cdn.signalwire.com/default-music/welcome.mp3",
      speech: {
        model: "enhanced.phone_call",
      },
      listen: {
        onStarted: () => console.log("Prompt started!"),
        onFailed: () => console.log("Prompt failed!"),
        onUpdated: (promptResult) => console.log("Prompt updated!", promptResult.result),
        onEnded: (promptResult) => {
          console.log("Prompt ended!", promptResult.result);
          call.hangup();
        }
      }
    }).onStarted();
  }
});
```
