Use your own PBX
Prepare an isolated Asterisk system and a dedicated, restricted outbound PJSIP endpoint. Keep carrier credentials inside your telecoms infrastructure.
DEVELOPERS / ONE OPEN CALLING PLATFORM
Build the calling
capability.
AI Dial-Tone's end-to-end design spans discovery, human permission, optional managed x402 admission, operator-controlled routing, real-time conversation, carrier-side hangup, and outcome evidence. This GitHub source is the development implementation of that product, not a separate BYOT-only offering. Version 0.0.1 provides runnable local Peer Lab media and experimental integrations, but no live public calling API.
BRING YOUR OWN TELECOMS / EXPERIMENTAL
Your Asterisk.
Your calling routes.
BYOT is for operators with an existing, isolated Asterisk/FreePBX environment and their own restricted PJSIP endpoint. AI Dial-Tone supplies an optional Python ARI/media adapter; it does not supply a SIP trunk or require managed x402 payments.
Enable local ARI
Configure loopback-only ARI access and set the connector's ARI, fixed-trunk, operator, and separate agent credentials.
Run the lab checks
Install Python 3.11+ and aiohttp, run the BYOT tests and python -m byot.server --check-config. Calling is disabled by default.
Authorise a bounded call
An operator issues a one-use destination-and-duration mandate. The agent joins using its own bearer and streams audio, without seeing ARI or SIP secrets.
Your telecoms, your authority. The human permits the task; the PBX or telco independently controls whether the call can be placed, which outbound route is permitted, and when it ends. The agent cannot change routes or override a refusal. The operator owns hard timeouts and recovery after a failure; AI Dial-Tone does not create or remove PBX routes for individual calls.
0.0.1 limitation: the adapter has passed simulated ARI/UDP tests, but not a live Asterisk, SIP trunk, or PSTN interoperability test. Do not use it on a production or shared PBX.
THE 0.0.1 CONTRACT
Two authenticated bots.
One controlled session.
No public PSTN calls, no online agent account, no x402 charge and no hosted MCP. Only the local experiment below is runnable today.
