A voice bot that works in production depends as much on the network and SIP as on the LLM. These three crafts rarely sit with the same person.
Infrastructure layer · IP & Linux
Ten years of integration and audits: LAN/WAN, firewalls, load balancers, penetration testing, 24/7 payment platforms. And daily Linux since the late ’90s. It is what runs underneath every call.
Linux, Cisco, Forcepoint, Checkpoint, Fortinet, F5, voice QoS
Signaling layer · SIP
Twelve years designing, rolling out and running multi-country contact centers: IVR, routing, campaigns, SBCs, CTI coupling with CRMs.
Genesys PureConnect (certified), Diabolocom, SIP, AudioCodes/Ribbon SBCs
Intelligence layer · LLM
Real-time voice agents, LLMs in call flows, automation. Built with AI coding agents through an industrialized workflow: specs, plans, reviews, tests, CI.
Streaming STT/LLM/TTS, on-prem AI, Kamailio, Asterisk, LiveKit, Claude Code, Grok
Twenty years of engagements, read like a call flow diagram: each row connects the crafts it involved.
