One programmable platform for media, AI, logic, and routing: a unified engine created by the team who invented modern telecom software
AI is transforming the world of real-time commmunications faster than many providers can keep up. Traditional CPaaS platforms like Telnyx still treat AI as an afterthought, forcing developers to stitch together media streams, external logic layers, and orchestration tools just to get something working.
SignalWire gives you the foundation you wish you had from the start. Built by the team behind FreeSWITCH, it combines native SIP connectivity, real-time media control, and intelligent routing in one programmable platform, with the visibility and support to back them up.
When something breaks, you need a real answer. Fast. Instead of waiting hours or days for a response, SignalWire puts actual engineers in your corner that respond right away.
SignalWire's turnaround time for messaging campaign approvals is unmatched at 48 hours or less. Get same-day brand approval and send texts in just a day or two.
Telnyx's deliverability issues lead to dropped calls and local numbers not receiving calls. SignalWire's distributed PoPs and routing stack reach every PSTN endpoint reliably, no matter where your customers are.
If you don’t know where your SMS went (or why it failed) how can you fix it? SignalWire gives you full observability across every message you send.
SignalWire lets you build multi-agent workflows that escalate, transfer, summarize, and take action, all in one real-time system.
Media control, AI logic, and routing decisions are all in the same pipeline. That means faster responses, fewer failures, and less infrastructure to maintain.

When you’re ready to launch, the last thing you need is to be stuck in limbo with The Campaign Registry.
SignalWire gets your brand and campaign approved fast, with concierge review to get it right the first time so you can start sending sooner.
With same-day brand approval, transparent, real-time status tracking, and a 48 hour campaign turnaround, you’ll never be left guessing when your messages will go through. Meanwhile, Telnyx users report multi-day delays and even week-long waits.
When your telecom platform wasn’t designed to support complex,
intelligent voice flows, every new feature turns into another engineering
burden - even the basics like transfers or state management.
Telnyx gives you pieces: SIP here, TTS/STT there, AI somewhere else.
You to stitch it together in a way that can be both expensive and slow.
SignalWire was built by the original creators of FreeSWITCH to remove
that integration tax with the real-time media plane, the routing
intelligence, and the AI runtime all in the same environment.
➙ Voice, messaging, video, AI orchestration, call logic, and routing are all in the same real-time pipeline.
➙ Native SIP, PSTN, and WebRTC handling means your AI and media share the same optimized backbone.
➙ SDKs let you deploy multi-channel, multi-agent apps without managing Redis clusters, load balancers, or event bridges.
