demarc#

demarc is a self-hosted AI receptionist and communications dashboard for a Telnyx-backed phone line. It answers inbound calls, carries a two-way spoken conversation, captures caller messages, sends and receives SMS, and keeps the operator's call history in a local SQLite database.

The service consists of a FastAPI runtime and a Next.js dashboard. Live voice uses Telnyx media streaming with configurable speech-to-text, language-model and text-to-speech providers. Fake providers are included for local evaluation.

Supported capabilities#

• Signed Telnyx voice and messaging webhooks.
• Bidirectional voice with interruption handling.
• Operator-provided knowledge and structured message capture.
• Number routing, calls, transcripts, SMS and runtime status in the dashboard.
• A Telnyx WebRTC browser phone.
• Configurable retention, migrations, readiness checks and backups.

demarc is designed for one operator. It is not a contact centre platform.

Call recording is available, and it is gated. It stays unavailable until you set a policy version and a disclosure notice, enable recording for the number, and record your own attestation; recordings are then retained for a bounded number of days that you configure. demarc does not read the disclosure to participants, so announcing the recording remains your responsibility. See Configuration.
