Overview

This guide walks through integrating Google’s Agent Assist with Salesforce using Twilio Flex as the call center platform. The setup enables real-time AI-powered agent suggestions during voice calls by streaming conversation data to Agent Assist.

Key Components

• Twilio Flex: Acts as the softphone inside Salesforce.
• SIPREC Connector: Forks call audio to Agent Assist for real-time analysis.
• Salesforce Lightning Web Component (LWC): Displays Agent Assist insights directly in the Service Console.
