Serverless Boilerplate - Twilio - Node.js - Forward a call

Twilio is a commincations API provide that allows developers to build applications using phone calls, SMS, emails and more. To configure communications a lot of services work with a configuration language called TwiML.

This example projects helps you deploy a serverless function to the Twilio runtime. The function responds the TwiML configuration to forward phone call.

Make sure serverless is installed globally. See installation guide.

You will also need to set up your Twilio account credentials using environment variables. You find these in your Twilio Console.

Needed environment variables are:

• TWILIO_ACCOUNT_SID
• TWILIO_AUTH_TOKEN
• MY_PHONE_NUMBER

1. Install Twilio Node.js Provider Plugin & Service Dependencies

npm install in this directory to download the modules from package.json.

2. Deploy

serverless deploy or sls deploy. sls is shorthand for the Serverless CLI command

3. Invoke deployed function

serverless invoke --function forward-call or serverless invoke -f forward-call

-f is shorthand for --function

In your terminal window you should see the response from Apache OpenWhisk

<?xml version="1.0" encoding="UTF-8"?><Response><Dial>+491...</Dial></Response>

Congrats you have just deployed and run your Forward Call function!
