Build In-Browser Calling with Twilio Voice JavaScript SDK
Twilio's Voice JavaScript SDK (formerly called "Twilio Client") allows your users to make and receive phone calls in their browsers. This tutorial will show you the front-end and backend code necessary to make browser-to-phone and browser-to-browser calls with the Voice JavaScript SDK.
Companies like Zendesk use Twilio Client to power their customer support centers. This tutorial and accompanying application power the support site for the Birchwood Bicycle Polo Co., which sells equipment to those who play "the sport of kings." It has three main features:
- Unsatisfied customers can submit support tickets with their phone number and their problem.
- Support agents can call customers' phones from their browser to follow up on support tickets.
- Customers can also use their browser to speak with support agents live when available.
Find your language and framework of choice below to get to the source code in your language and follow step-by-step instructions to learn how to build in-browser calling yourself.
