Asterisk PBX Information System

This project involves the creation of a small information system using Asterisk PBX within Docker containers. Below is an outline of the system architecture and components.

System Schema

The system consists of the following components:

• 3 Docker Containers:
  1. Asterisk
  2. Backend (FastAPI)
  3. HTTPS Proxy

Components

• Asterisk Server (asterisk.vsb.cz):

  • Phones with numbers 10 and 11 connected to Asterisk via port 5060 using the PJSIP protocol.
  • Phones communicate with Asterisk using RTP protocol over ports 10000-10100.

• Backend:

  • Bidirectional communication with Asterisk through the Asterisk Manager Interface (AMI).

• HTTPS Proxy:

  • Communicates bidirectionally with the Backend via HTTP.
  • HTTPS Proxy listens on port 443.

Asterisk Configuration

Using Asterisk version alpine-20.5.2, you will configure the following:

1. PJSIP Accounts:

   • Phone 10 (number 10)
   • Phone 11 (number 11)

2. Conference:

   • Conference reachable on number 18.

3. Simple IVR (Autoattendant):

   • Multi-level IVR system with at least two levels.

4. Trunk Connection:

   • Establish a trunk connection to asterisk.vsb.cz, which is the university's Asterisk server.

Backend

The backend will be built using FastAPI. The main functionality of the backend will include a simple interface, allowing users to perform operations like making calls (from one number to another).

Docker Containers Setup

The system will run within Docker Desktop, with three containers configured as follows:

1. Asterisk Container:

   • Handles phone communication, IVR, and conference calls.

2. Backend Container (FastAPI):

   • Provides an API interface for interaction with the Asterisk PBX.

3. Proxy Container (HTTPS Proxy):

   • Manages HTTPS communication between the Backend and external systems, using port 443.

Summary

The system integrates Asterisk PBX with a FastAPI backend and an HTTPS proxy, facilitating communication between phones, handling IVR and conference calls, and providing a simple API for managing calls.
