Vitaliy N.

I am a senior VoIP Engineer with over 15 years of experience designing and deploying SIP-based telephony solutions. I have strong hands-on expertise with Asterisk, FreeSWITCH, Kamailio, OpenSIPS, Kazoo, and Jambonz, and I specialize in building reliable, high-availability VoIP systems for production environments. In addition, I have extensive experience integrating SIP call flows with AI voice agents over WebSocket, supporting real-time, bidirectional audio. I have built conversational voice bots end to end, including streaming STT, LLM-based dialog logic, and low-latency TTS, delivering natural and responsive voice interactions. I focus on scalable, secure, and low-latency solutions that bridge traditional telephony with modern AI-driven voice systems.
