The real difference
Most voice AI providers rely on third-party telephony and public cloud infrastructure, which introduces latency, unpredictable costs, and integration gaps. Telnyx takes a different approach. As a licensed telecom provider, we deliver direct PSTN access and global numbers in 140+ countries. By also owning and operating a private global IP network, telephony stack, and GPU infrastructure, we give you programmable control over every layer of the call flow. The result is sub-200ms round trip latency, transparent usage-based pricing, and reliable real-time performance without depending on outside vendors.
COMPARISON
Compare our features
Every voice AI provider takes a slightly different approach. Some focus on text-to-speech, others on orchestration, and many rely on third-party telephony to complete the stack. Still, most solutions leave critical gaps in latency, control, or cost transparency. Telnyx unifies it all in one platform, with global telephony, real-time AI infrastructure, and flexible orchestration to make building Voice AI Agents faster and easier.
Licensed carrier in 30+ countries with native SIP trunking, global numbers, and routing built in.
Depend on third-party carriers or SIP providers, creating extra cost and integration overhead.
