Built differently for India: owned, integrated, and within the region
Most voice AI platforms orchestrate across rented infrastructure, often with servers based in the US or Europe. For businesses in India and South Asia, that means latency, dropped calls, and an experience that feels anything but local.
Telnyx is different. We spent over a decade building a carrier-grade voice network, then colocated compute directly with our telephony infrastructure. The result: sub-200ms latency, calls that get answered, and reliability no Frankenstack can match.
We are not an orchestration layer on top of someone else's stack. We are the infrastructure.
Because we own it, you pay less. Voice AI agents at a fraction of competitor cost, production-ready in minutes.
- Sub-200ms latency: Owned network infrastructure means your voice AI agents respond in real time. No routing through US or EU servers.
- One integrated platform: Voice AI, STT, TTS, SIP trunking, and phone numbers from a single provider. No Frankenstack, no multi-vendor debugging.
- India data sovereignty: Traffic stays in-region. DLT-registered, TRAI-compliant, and enterprise-ready for regulated industries.
