🎯 Project Overview

Built a centralized automation platform to manage multiple VoIP servers from a single web interface. The system eliminates manual SSH commands and error-prone text file editing by providing one-click deployment, configuration generation from templates, and live terminal output streaming.

💼 Business Impact

95% time savings: Deployment time reduced from 30 minutes to under 2 minutes per server
Error reduction: Configuration mistakes dropped from ~15% to <1%
Audit compliance: Complete change history with who/what/when for every deployment
Team scalability: Non-technical staff can now deploy configurations safely
Disaster recovery: One-click rollback to previous configurations

🛠️ Technical Architecture

Core Technologies

Laravel 11 - Backend API and admin interface
PHP 8.2 - Core application logic
phpseclib3 - Secure SSH2 connections
MySQL 8 - Server inventory and configuration storage
Redis - Queue management for background jobs
Server-Sent Events (SSE) - Real-time terminal output streaming
Vue.js 3 - Reactive frontend components
Tailwind CSS - Modern UI design

System Capabilities

✅ Multi-Server Management

Add/edit/delete VoIP servers from web interface
Group servers by region, function, or client
Batch operations across server groups
Real-time status monitoring (online/offline)

✅ Configuration Generation

Import SIP trunk details from Excel/CSV templates
Template-based config generation (PJSIP, SIP, IAX2)
Automatic validation before deployment
Preview changes before applying

✅ One-Click Deployment

Deploy configs to /etc/asterisk/ via SSH
Update MySQL Realtime database entries
Atomic operations with automatic rollback on error
Asterisk reload commands executed remotely

✅ Live Monitoring

Stream SSH terminal output in real-time (SSE)
Deployment status dashboard
Error tracking with automatic notifications
Complete audit logs with search and filtering

🔧 Technical Challenges Solved

SSH Connection Pooling

Challenge: Opening/closing SSH connections for every command was slow (3-5 seconds per operation).

Solution: Implemented connection pooling with Laravel cache. Connections stay alive for 5 minutes, reducing overhead from seconds to milliseconds.

Concurrent Deployment Race Conditions

Challenge: Multiple users deploying to same server simultaneously caused conflicts and file corruption.

Solution: Added mutex locks per server using Redis. Deployments queue automatically when server is busy.

Configuration Validation

Challenge: Invalid configs would break Asterisk after deployment, causing downtime.

Solution: Pre-deployment validation using asterisk -rx "pjsip show endpoint test", automatic backups before every change, and rollback on error detection.

Real-Time Output Streaming

Challenge: Users couldn't see what was happening during deployments—felt like a black box.

Solution: Implemented Server-Sent Events (SSE) to stream command output line-by-line. Users see exactly what's executing in real-time.

💡 Key Features

Carrier Management

Import from Excel: Upload carrier details spreadsheet, auto-generate configs
Template Library: Pre-built templates for major carriers (Bandwidth, Twilio, Telnyx)
Codec Optimization: Automatic codec selection based on carrier requirements
Authentication Presets: Support for IP auth, username/password, certificate-based

DID Management

Bulk Import: Import thousands of DIDs from CSV
Auto-Routing: Automatically create inbound routes based on patterns
E911 Integration: Associate emergency addresses with DID ranges
Usage Analytics: Track which DIDs are active/inactive

Deployment Pipeline

Staging Environment: Test configs on staging server before production
Approval Workflow: Optional approval requirement for production deployments
Scheduled Deployments: Deploy during maintenance windows automatically
Health Checks: Post-deployment verification tests

🔐 Security Features

Encrypted Credentials: SSH passwords stored using Laravel encryption
Role-Based Access: Different permission levels (viewer, deployer, admin)
Two-Factor Auth: Optional 2FA for sensitive operations
IP Whitelist: Restrict access to known office/VPN IPs
Audit Logging: Every action logged with timestamp and user identity

🚀 Results

✅ Reduced deployment time by 95% (30 min → 2 min)
✅ Eliminated 99% of configuration errors
✅ Enabled non-technical staff to deploy safely
✅ Complete audit trail for compliance
✅ Deployed to production managing 50+ servers
✅ Saved 20+ hours/week of manual SSH work
