Retell AI is a popular voice agent framework built primarily for US developers. However, Indian businesses and developers attempting to deploy Retell AI in India quickly encounter significant friction: expensive USD per-minute pricing, credit card foreign transaction fees, complex Twilio SIP trunking configuration, and audio latency delays when routing calls from US servers to Indian mobile phones.
Vistara AI is engineered as the complete, India-first alternative to Retell AI. We combine the flexibility of modern prompt engineering and REST APIs with direct Indian carrier trunking, native Hinglish speech-to-text, and transparent INR billing.
