Livekit-Asterisk Integration
Haris is highly professional, skilled, and very easy to work with. He clearly understands complex technical requirements and delivers quality work on time. Communication was smooth throughout the project, and he was proactive in solving issues and suggesting improvements. I would definitely recommend him for similar integrations and would be happy to work with him again.

━━━━━━━━━━━━━━━━━━
🔧 WHAT MAKES ME DIFFERENT
━━━━━━━━━━━━━━━━━━
Most "AI voice" freelancers plug together Vapi + ElevenLabs and call it done. I go deeper:
✅ Custom LLM pipelines — not just API wrappers
✅ Asterisk/FreePBX + LiveKit WebRTC — legacy and modern telephony, both
✅ SIP trunk design, SBC architecture, RTPengine — the infrastructure layer most devs skip
✅ Kernel-optimized Linux for real VoIP workloads
✅ Your data stays yours — zero vendor lock-in
━━━━━━━━━━━━━━━━━━
⚙️ CORE STACK
━━━━━━━━━━━━━━━━━━
Voice AI → OpenAI · Deepgram · Whisper · LiveKit
Telephony → Asterisk · FreePBX · Kamailio · RTPengine · SIP/RTP
MLOps → Docker · Kubernetes · AWS · GCP
Systems → Arch Linux · eBPF · Bare-metal tuning
━━━━━━━━━━━━━━━━━━
📌 REAL DEPLOYMENTS
━━━━━━━━━━━━━━━━━━
✅ High-availability telephony infrastructure — Eracon Technologies
✅ Privacy-first communication platform — Asctech Digital Inc.
✅ Enterprise AI voice automation — Hungarian Construction Inc.
✅ Large-scale Linux server & network ops — COLAB
━━━━━━━━━━━━━━━━━━
🛡️ COMPLIANCE & CALL FILTERING
━━━━━━━━━━━━━━━━━━
✅ DNC (Do Not Call) list filtering & TCPA compliance automation
✅ AI-powered spam/robocall detection and blocking
✅ Call authentication — STIR/SHAKEN framework implementation
✅ Outbound campaign filtering for FCC/FTC compliance
✅ Real-time number scrubbing against federal & state DNC registries
✅ Fraud detection pipelines for high-volume call centers
━━━━━━━━━━━━━━━━━━
✅ YOU NEED ME IF...
━━━━━━━━━━━━━━━━━━
→ Your current IVR is losing you customers
→ You need AI calling that works on YOUR infra
→ Your telephony stack is failing under load
→ You want voice + CRM + SMS in one pipeline
→ You run outbound campaigns and need DNC/TCPA compliance
→ You're getting spam flags on your outbound numbers
→ You need it built right, once, with docs
📩 Message me. Tell me your current setup and I'll tell you exactly what's possible.

Delivery time starts when Haris receives requirements from you.
Haris works on your project following the steps below.
Revisions may occur after the delivery date.
Architecture & Call Flow Design
We will align on the technical architecture, SIP trunk routing, and the exact conversational flow and business logic your AI agent needs to follow.
Infrastructure & Server Setup
I will provision secure cloud servers, configure your SIP trunks, and deploy the required Asterisk, FreePBX, or LiveKit environments.
