Asterisk Web Dialer with JACK

This project provides a Docker Compose setup for:

• Asterisk built with JACK audio support (chan_jack)
• A Node.js Web UI to dial numbers via Asterisk AMI
• Exposes JACK audio ports for call audio monitoring

Prerequisites

• Linux host with JACK server running (e.g., jackd, QJackCtl)
• Docker & Docker Compose

Configuration

1. Edit SIP provider credentials in asterisk/config/sip.conf.
2. Update AMI credentials in asterisk/config/manager.conf and web/src/index.js (via environment variables).

Usage

1. Start services:

   Bring up both Asterisk (with JACK) and the Web UI

   docker-compose up --build

   Or in detached mode:

   docker-compose up -d --build

   For local Linux testing, Asterisk uses host networking

   SIP (5060) and RTP ports (10000-10100) are bound directly on the host

   Ensure no other service is using UDP 5060 or your RTP range

2. Access Web UI at http://localhost:3000.

3. (Optional) Test AMI connectivity:

   • Via HTTP: curl:

     curl http://localhost:3000/health

     You should get { success: true, amiResponse: ... }.
   • Via Web UI: click the Check AMI Health button on the page and look for the Health response: log in your browser console.

4. Enter a phone number and click Call.

5. Use a JACK client (e.g., QJackCtl, Carla) to connect to the 'asterisk' JACK port to listen to call audio.
