High-Scale VoIP Extension System

A high-scale VoIP system built for a golf course network, supporting 10,000 extensions with real-time communication and 150+ concurrent calls validated through stress testing.

Asterisk SIP Real-time
High-Scale VoIP Extension System

Project Overview

This project focuses on building a large-scale VoIP communication system for a golf course company, where embedded extension devices in golf carts and facilities allow direct communication with staff and the front desk.

The system is powered by Asterisk, handling SIP communication, dialplan execution, and real-time call routing across thousands of endpoints. A real-time data layer ensures instant synchronization of extension states and call events throughout the system.

To ensure reliability under real-world conditions, a custom stress testing setup was developed to simulate 10,000 active extensions and validate performance with 150 simultaneous calls, confirming stability at scale.
