How AI Voice Calling Works: Automated Phone Calls for Sales, Support, and Outreach
Evaro's AI voice calling feature uses Twilio telephony and natural-sounding OpenAI voices to make and receive phone calls on behalf of your business. Configure your AI voice agent with a custom script, personality, and knowledge base, then let it handle outbound cold calls, appointment reminders, follow-up calls, customer satisfaction surveys, and inbound support lines. Each call is recorded and transcribed automatically, giving you a searchable record of every conversation along with analytics on call duration, outcomes, and sentiment.
Unlike traditional robocalls, Evaro's voice agents carry on natural, two-way conversations. The AI listens, understands context, and responds in real time with human-like speech patterns. This makes it ideal for use cases like sales prospecting, lead qualification, payment reminders, event confirmations, and after-hours customer support. You can schedule calls in bulk, set up recurring campaigns, or trigger calls automatically through workflow automations.
Getting started is simple: connect your Twilio account, choose a voice, upload your call script, and launch your first campaign. Learn more about the full set of platform features or see how Evaro works to understand how voice calling fits into the broader AI automation toolkit.
