# Kallix > Kallix is a voice AI platform to build, test and run AI agents that make and answer phone calls in Hindi, English, Hinglish and more, with WhatsApp follow-ups, CRM sync and analytics built in. Kallix (Kallix Labs Private Limited, founded 2026, Noida, India) is a voice AI platform. Teams build, test, launch, measure and improve AI agents that make and answer phone calls in Hindi, English, Hinglish and more, with WhatsApp follow-ups, CRM sync, webhooks and a REST API. Agents always say they are AI in their first line and offer a person. Call data is stored and processed in India and Kallix is DPDP Act compliant. Kallix follows TRAI's rules for commercial calls: it checks every number against the DND register (NCPR) before a campaign dials, declares automated (A2P) calling for the numbers it provides through its telephony partner Vobiz, and whitelists customers' calling numbers with Truecaller and the telecom operators. During a call an agent can check a connected calendar and book a slot. ₹500 in free credits on sign-up (about 100 minutes). Pricing: ₹4.80 per minute, billed in 30-second pulses; 2 concurrent calls included, extra concurrency ₹999/month each; phone numbers billed separately, from ₹499/month each (billed every 3 months; rates per number in the dashboard). The per-minute rate covers everything a call uses (voice, speech recognition, the language model, Indian call minutes and operator charges) except GST. Enterprise volume pricing on request. ## Platform - [Platform overview](https://www.kallix.in/platform) - [Agent studio](https://www.kallix.in/platform/agent-studio): Build AI voice agents in Kallix AI from a template or a plain-words brief.
