Where I take what I've learned operating those businesses and apply it directly to client problems. No agency layer, no junior team — just engineering judgement.
The bridge
The market is bifurcated. Traditional voice consultants understand SIP, PBX, contact-centre design, carrier-grade infrastructure — but treat AI as someone else's problem. AI consultants understand LLMs, prompts, agent frameworks — but couldn't read a SIP trace if it saved the project.
Both are needed. Right now, almost no one is fluent in both.
That's the gap I sit in. Voice agents that work in production aren't built by gluing an LLM to a Twilio number — they're built by people who know what jitter does to ASR, why your IVR fallback matters, and how to escalate to a human without losing the call.
