Voice Call Setup

Sarudo's voice calling feature lets your AI employee make and manage phone calls on your behalf. The system uses Twilio for phone number provisioning and call routing, and Vapi for AI-powered autonomous conversations. This means your AI employee can place calls using a real phone number, have natural conversations with the person on the other end, and provide you with full transcriptions afterward. Voice calling is an optional add-on configured during onboarding.

To enable voice calling, you need a Twilio account. Twilio is a trusted communications platform used by millions of businesses worldwide. During onboarding, your setup team will help you create a Twilio account (or connect an existing one), purchase a phone number in your preferred area code, and configure the API credentials. The phone number becomes your AI employee's direct line — calls made by your AI employee show this number as the caller ID.

You can choose a phone number with a specific area code to match your business location. Twilio offers local, toll-free, and international numbers. Once provisioned, this number is dedicated to your Sarudo instance. When your AI employee makes a call, the recipient sees this number. You can also receive calls on this number, though Sarudo currently focuses primarily on outbound calling capabilities.

Vapi powers the AI side of phone conversations. It enables your AI employee to speak naturally, understand responses in real-time, and adapt the conversation based on what the other person says. Vapi integration is configured automatically when voice calling is enabled. The AI voice is natural-sounding and can be customized to match your preferences — male or female voice, speaking speed, and accent options are available.
