FAQ
Frequently asked questions
How can AI improve customer engagement?
AI enhances customer engagement by delivering timely, personalized interactions at scale, including reminders, updates, check-ins, and feedback collection. With telli, conversational voice AI handles these touchpoints automatically, confirming appointments, gathering insights, answering questions, and keeping customers consistently connected, all while syncing the exact data your team cares about back into your CRM.
Can telli retrieve customer data in real time?
Yes. telli connects directly to your CRM and business systems to pull customer records the moment a call begins. It can access history, preferences, and account details instantly, enabling personalized conversations, accurate verification, and smoother call handling. Your team receives fully updated, real-time information for every interaction.
Can I optimize telli’s AI voice agents?
Yes. telli includes a powerful prompt editor called telli studio that allows you to refine responses, workflows, and conversation logic. You can adjust tone, instructions, and behavior to match your brand and operational needs or our team can help you do so. Continuous optimization helps your AI receptionist become smarter, more accurate, and more aligned with your customer experience goals.
Do telli’s AI voice agents sound like AI?
No. telli’s AI voice agents are designed to sound natural, human-like, and conversational. Our customers consistently report that callers don’t realize they’re speaking with AI — and many find it hard to believe even after being told. The result is a smooth, engaging experience that feels like talking to a real person.
