Complex voice app builds using Asterisk usually bottleneck at dial plan design and seamless failover to human agents. Integrating AI voice workflows also means tight REST hooks and reliable SIP call state tracking. I built and maintained an Asterisk/PJSIP system routing calls to AI agents and live staff, with click-to-call, DID management, CRM integration, REST/AMI/ARI control, and reporting. Node.js for backend integrations; MySQL for call logs and routing logic. Your list spans custom dial plans, inbound/outbound flows, webhook and AI integration, and multi-channel (WhatsApp/SMS/Email) triggers. For AI, I interface with OpenAI, Azure Speech, and Google Speech; can add Deepgram/ElevenLabs if that's your stack. Which CRM do you want to sync, and does your AI voice agent send call transfer events via HTTP or direct SIP notify? I can start this week if requirements are clear. Pradeep

Your project combines several areas that need to work reliably together: Asterisk/PJSIP configuration, API orchestration, AI voice workflows, and scalable backend integrations. My focus would be on building a stable telephony flow with clear separation between SIP signaling, business logic, and AI interaction layers to simplify maintenance and troubleshooting. I can help with REST/webhook integrations, call flow orchestration, IVR logic, click-to-call workflows, CRM connectivity, and AI voice agent integrations using Node.js or Python services connected to Asterisk through AMI/ARI APIs. I also have strong experience with scalable backend systems, PostgreSQL, cloud infrastructure, Docker-based deployments, and observability, which is important for RTP/SIP diagnostics, failover handling, and production reliability. For AI integrations, I can work on STT/TTS orchestration pipelines, human handoff logic, webhook-driven conversational workflows, and integration with external AI services. I am also comfortable working with Linux environments, Git workflows, and performance-focused backend architectures. A good first step would be reviewing the current telephony topology, SIP providers, routing logic, and existing integrations to identify bottlenecks and define a stable implementation plan for the next iterations.

Hi, The most valuable part of your project isn't connecting AI to telephony—it's creating a reliable communication platform where voice infrastructure and AI work together without interrupting the customer experience. What caught my attention is your focus on seamless call routing, intelligent failover, API integrations, and future AI capabilities. That requires more than feature implementation; it requires an architecture that remains stable as call volume and integrations grow. I'd approach the platform as a modular system where telephony, AI services, CRM integrations, and communication channels remain loosely coupled, making future enhancements easier while keeping operations reliable. One question: As Neurova evolves, is your priority supporting higher call volumes or expanding AI voice capabilities across more communication channels? I'd love to discuss your vision.
