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.

Low-latency voice
Most voice AI stacks route calls through 4 to 5 separate providers, including telephony, STT, LLM, TTS, orchestration, adding latency at every hop. Telnyx runs everything on one network. Audio enters, gets processed, and returns without leaving our infrastructure. The result: sub-200ms round-trip times that keep conversations natural.
Noise suppression
Crystal-clear audio is the foundation of great customer experience. Telnyx noise suppression and HD Voice codecs filter out background noise before it reaches your agent, so conversations feel natural, and customer names, account numbers, and key details are captured accurately the first time.
