Every other CPaaS is middleware on someone else's network
Every hop between your app and the network adds latency, drops events, and takes a margin. The usual path: your app to an API to an aggregator to a carrier to the PSTN. The Telnyx path: your app to Telnyx to the PSTN. We don't translate telephony events. We originate them.
Three things only the carrier can do
Everyone else inherits them upstream. We sign them at our own switch.
Carrier identity
When you call through a reseller, your caller ID gets diluted. When you call through us, your identity is verified at the source. Your brand shows up on the recipient's screen, your calls pass spam filters, and AI vs. human traffic is caught before it reaches you.
Carrier compliance
We handle 10DLC, TCPA and GDPR across 30+ licensed countries, so every message and call you send is already compliant. One set of rules for voice, SMS and WhatsApp.
Carrier economics
Resellers buy from carriers and add markup. We own the switch, so there's no middle layer. 50% less than Twilio, no hidden surcharges, one bill for everything.
PRODUCTS
All your communication needs, on infrastructure built for reliability.
SUPPORT
When your agent drops at 2am, one team fixes it. Not four
We own the stack, so we own the problem. One team traces your issue from carrier to inference. 24/7, every tier, no paywall. Real engineers, not a ticket queue.
Full trace per incident
One correlated trace across the entire call path. Carrier to inference, no gaps, no finger-pointing.
Free 24/7, every tier
No paywall on help. Real engineers pick up, not a bot reading a script.
Dogfooded AI support
We run our support on our own voice AI. Many issues resolve before you even notice.
Migration support included
Switching from Twilio or Vonage? We help you migrate. No consultant fees, no timeline guessing.
