Twilio and Salesforce are being used together to make it possible to communicate with customers directly from a browser, allowing sales teams to save time when chasing leads and managing demos. This integration is made possible by using Twilio Client, WebRTC, and the newly updated SFDC library, enabling features like screen pops and in-browser calling. The combination of Twilio and Salesforce can help support and sales teams work more efficiently, with Coca-Cola Enterprises being a notable example of how this technology has improved their customer service experience.
