Title: Excellent AI Voice Platform for Business Automation Rating: ⭐⭐⭐⭐⭐ (5 stars) Review: I've been using Retell AI for about 3 months now to build voice agents for my clients' businesses, and I'm really impressed with the platform. The setup process is straightforward, and the integration with Cal.com and other tools works seamlessly once configured properly. The voice quality is natural and the latency is minimal, which is crucial for customer-facing applications. What stands out most is the flexibility - I can customize agents for different industries like roofing, real estate, and service businesses. The function calling capabilities are robust and allow for complex workflows. The support team is responsive when issues come up, and the documentation is comprehensive. For anyone building AI phone agents for appointment booking, lead qualification, or customer service, Retell is a solid choice. My only suggestion would be more generous trial credits for testing, but overall it's been a great platform for my agency work. Would recommend: Yes
