The modern open source voice infrastructure

Run your own voice infrastructure on a single Linux box. Bring your own SIP trunk, run one install script, and get browser dialers, queues, call recording, AI transcription, and a real-time voice bot — free and AGPL-licensed.

Self-host for free Star on GitHub Try Comcent Cloud

Rather not run servers? Comcent Cloud is the managed version, from $20/month.

From blank server to first call

Comcent Community Edition is fully open source (AGPL-3.0) — self-host it on any Linux box in four steps.

Watch the full installation walkthrough — from blank server to first call.

1

Get a server ready

Any Linux host with a public IP — a $12/mo VPS is plenty. Point a DNS record at it and open the SIP & web ports.
2

Run the installer

One command installs Docker if needed, generates secrets, and lays everything out. Takes about 30 seconds.
3

Configure & start

Fill in your domain and storage details in .env, then docker compose up -d.
4

Claim it & call

Open /setup with the one-time token, connect your SIP trunk (Twilio, Telnyx, …), and make your first call.


curl -fsSL https://raw.githubusercontent.com/comcent-io/comcent-ce/main/install.sh
          | bash
