The bridge stays thin
Your agent owns the conversation.
cxntion handles SMS webhooks, tunnel routing, delivery bookkeeping, and reviewed beta number activation. The model, memory, tools, policy, and personality remain in the agent you already run.

Run the CLI
Init, doctor, and connect from the same machine that can reach your agent endpoint.

Activate a beta SMS number
After review and paid beta activation, cxntion uses its approved Twilio A2P campaign, SMS webhooks, and outbound tunnel.
- 03
The agent texts back
Every message arrives with channel, caller, timestamp, context, and a request ID.
Why us?
Why cxntion wins the boring parts.
The hard part is not forwarding one SMS webhook once. It is making delivery, routing, cost guardrails, and runtime behavior hold together cleanly every day.
- SMS is first-classsub-second handoff
Texting runs through its own production path, so replies stay fast, measured, and independent from any future channel work.
- Bridge, not lock-inno agent patching
Hermes, OpenClaw, or any OpenAI-compatible endpoint can stay exactly where it already runs.
- Costs are visible early250-500 segments
Starter and Pro are designed around SMS segment math, carrier fees, A2P costs, and soft warnings before surprises.
- Built for self-hostingworks behind NAT
The tunnel is outbound, so droplets, Fly machines, Railway apps, and local servers all fit the same model.

Voice alpha
Voice is in alpha. SMS is the launch path.
cxntion is proving a managed voice architecture in internal R&D, but public beta customers are buying managed SMS. Voice is not a customer entitlement yet.

- 01
A caller starts a voice-alpha session
Twilio Media Streams carries internal test audio into cxntion's signed media stream path.

Deepgram runs the realtime voice layer
Deepgram Voice Agent handles speech, turn taking, and interruption while cxntion keeps routing and auth.
- 03
The user's agent still thinks
The signed think gateway reaches the same outbound tunnel model before the response returns to the call.
