+To make a call, you need to enable the voice capability on your Vonage application. Copy this code into the `enable-voice.js` file:
+
+```js
+const { Vonage } = require('@vonage/server-sdk');
+
+const vonage = new Vonage({
+    apiKey: process.env.VONAGE_API_KEY,
+    apiSecret: process.env.VONAGE_API_SECRET,
+    applicationId: process.env.VONAGE_APPLICATION_ID,
+    privateKey: process.env.VONAGE_PRIVATE_KEY,
+});
+
+vonage.applications.getApplication(process.env.VONAGE_APPLICATION_ID)
+    .then((app) => {
+        app.capabilities = {
+            voice: {}
+        }
+        vonage.applications.updateApplication(app)
+            .then(() => console.log("App Updated"))
+            .catch((error) => console.dir(error));
+    })
+    .catch((error) => console.error(error));
+```
+
+Then run this command in the Terminal:
+
+```sh
+node enable-voice.js
