onCall(callback: string)

Handle Call Webhooks

In the route specified with the callback parameter, you can return an NCCO to instruct the Voice API on how to handle the call.

const session = vcr.createSession();
const voice = new Voice(session);

await voice.onCall("onCall");

app.post('/onCall', async (req, res, next) => {
    const ncco = [
        {
            action: 'talk',
            text: "Hi from Vonage!",
        }
    ];
    res.json(ncco);
});
