Building Scalable IVR Systems with Laravel and RabbitMQ

At Viamo, we built an IVR system processing over 100,000 calls daily. Here's what we learned.

System Architecture

The system consists of:

• Laravel backend for business logic
• Vue.js frontend for management dashboard
• RabbitMQ for queue management
• Tree-based call flow execution

Queue Management

// Laravel job for call processing
class ProcessCall implements ShouldQueue
{
    public function handle()
    {
        // Process call through tree structure
        $this->executeCallFlow();
    }
}

Performance Optimization

• Optimized tree traversal algorithm (10% improvement)
• Implemented connection pooling
• Added comprehensive monitoring
• Built retry mechanisms for failed calls
