Twilio功能:接收到来电时发送WhatsApp消息

Question

我想在接收电话时使用Twilio functions来运行我的操作。

简单任务：当我在Twilio号码上接到电话时，我想转发电话，还将消息发送给WhatsApp号码以告知即将到来的电话。

Twilio网站上有一个类似的示例：https://support.twilio.com/hc/en-us/articles/360017437774-Combining-voice-voice-sms-sms-sms-and-fax-twiml-in-twiml-in-in-the-same-same-response

，但我无法与WhatsApp一起使用。它仅适用于SMS消息，但是当我用whatsapp:[phone]号码替换to和from参数时，我没有收到任何消息。

我正在发布一种方法，用我的twilio whatsapp sandbox进行了测试，它有效。

/**
 *  This Function will forward a call to another phone number.
 *  It will send a WhatsApp message before doing that. 
 */
exports.handler = function (context, event, callback) {
    let fromNumber = event.From; // number which called our Twilio number  
    let recipientNumber = '[phone]'; // number where the call will be forwarded
    let client = context.getTwilioClient();
    client.messages
        .create({
            from: 'whatsapp:[phone]', // Twilio's WhatsApp sandbox number
            body: `Call from ${fromNumber}, forwarded to ${recipientNumber}.`,
            to: 'whatsapp:[phone]' // WhatsApp number registered with sandbox
        })
        .then(function (message) {
            console.log(message.sid);
            forwardCall();
        });
    function forwardCall() {
        // generate the TwiML to tell Twilio how to forward this call
        let twiml = new Twilio.twiml.VoiceResponse();
        let dialParams = {};
        twiml.dial(dialParams, recipientNumber);
        // return the TwiML
        callback(null, twiml);
    }
};
