Production AI call agents on LiveKit Agents + OpenAI Realtime API / Gemini Live / Vapi / Retell / Pipecat, Deepgram Voice Agent for ASR, ElevenLabs Turbo / Cartesia Sonic for TTS. Sub-300ms first token, sub-800ms full reply, sub-1.5s tool-call return. Twilio Voice / Telnyx / FreeSWITCH / SIP / PSTN. Same team behind Nucleus (Fibernetics) — 600M+ call minutes/month across 5,000+ businesses, SOC 2 Type II / HIPAA / GDPR. 625+ real-time products since 2005.
We develop AI-powered call agents for real production use — not demos. These agents answer calls, understand intent, respond with natural voice, and plug into existing business systems. Examples from our portfolio: an AI appointment-booking voice assistant for healthcare that verifies caller identity, checks patient status, presents provider availability, books the slot, and schedules reminders automatically; a hospital phone interpreter on SIP/FreeSWITCH with IVR language menu connecting doctors to live interpreters in seconds; and Nucleus, where AI phone agents carry 600M+ call minutes per month on behalf of Fibernetics's 5,000+ business customers.
No matter the size or complexity of your project, we’ll take it on and get it done.
Low-latency audio pipelines on LiveKit Agents (WebRTC SFU + voice-pipeline orchestration), Twilio Voice / Telnyx / FreeSWITCH for SIP / PSTN, Deepgram Voice Agent for end-to-end. Sub-300ms first token, sub-800ms full reply, real-time interruption / barge-in handling.
Conversation logic on OpenAI Realtime API, Gemini Live, Vapi, Retell, or Pipecat orchestrator with GPT-4o / Claude 3.5 Sonnet / Gemini 1.5 Pro. Tool-use, function-calling, structured outputs, RAG over your knowledge base, fallback chains, deterministic call flows when needed.
Native integrations: Twilio Voice / Telnyx / FreeSWITCH for telephony, Salesforce / HubSpot / Zoho CRM, Calendly / Cal.com / Google Calendar for scheduling, Epic / Cerner / MEDITECH (FHIR) for healthcare, Stripe for payments, custom REST / gRPC for internal APIs. The agent is part of your stack, not a sidecar.
Custom AI call agents for every case — inbound support (Nucleus pattern), outbound sales (Vapi / Retell), appointment booking (Calendly / Epic), telemedicine intake (FHIR + HIPAA), debt collection, lead qualification. LiveKit Agents + OpenAI Realtime + Twilio Voice. SOC 2 / HIPAA / GDPR ready.
Have an idea? We’ll turn it into a fully working app – from design and backend to launch and support.
Got a product that needs more speed, stability, or features? We’ll make it stronger and ready to scale.
Struggling with unfinished or broken code? We’ll step in, clean it up, and get your project back on track.
Our AI call agents are designed for real-time, production-grade voice workflows. Every component is mapped in architecture blocks and data flow diagrams, showing how audio travels through the system, where AI operates, and how reliability, scale, and compliance are ensured. The same pipeline powers Nucleus's 600M+ monthly call minutes and the medical NDA assistant we built for end-to-end appointment booking over voice.

Real talk on LiveKit Agents, OpenAI Realtime, latency budgets, telephony, and HIPAA — from the team that ships it.
Audio comes in over WebRTC (LiveKit Agents) or PSTN / SIP (Twilio Voice / Telnyx / FreeSWITCH). Deepgram Nova-3 streams partial transcripts (~150ms first partial). LLM (OpenAI Realtime / Gemini Live / GPT-4o / Claude 3.5 Sonnet via Vapi or Pipecat) generates response with tool-calling. ElevenLabs Turbo / Cartesia Sonic streams TTS back — first audio in 90–250ms. Total: sub-300ms first token, sub-800ms full reply.
Production budgets: ≤ 300ms first token, ≤ 800ms full reply, ≤ 1.5s tool-call return (e.g. CRM / scheduling / EHR query). With Cartesia Sonic + Deepgram Nova-3 we hit sub-500ms full reply. OpenAI Realtime API is ~250ms first audio out-of-the-box. Nucleus carries 600M+ minutes/month at these budgets in production.
Yes. Controlled handoff via Twilio Voice / Telnyx warm transfer, SIP REFER, or LiveKit room join. Triggers: low confidence, intent keywords, explicit user request, or business-rule escalation. Full conversation context (transcript + summary) handed to the human agent at the moment of transfer.
Yes. SOC 2 Type II / HIPAA / GDPR / PCI-DSS frameworks deployed in production. FHIR / Epic / Cerner / MEDITECH for healthcare. PII redaction, audit logs, RBAC, SIP TLS + SRTP, on-prem self-hosting if required. Nucleus (Fibernetics) is HIPAA-compliant on 600M+ minutes/month.
Telephony: Twilio Voice, Telnyx, Vonage, FreeSWITCH, SIP / PSTN. CRM: Salesforce, HubSpot, Zoho. Scheduling: Calendly, Cal.com, Google Calendar, Outlook. EHR: Epic, Cerner, MEDITECH (FHIR). Payments: Stripe. Internal: REST / gRPC / Kafka / GraphQL. Anything with an API plugs in.
Fully. We mix LLM-driven open conversation (OpenAI Realtime / Vapi) with deterministic state machines (Pipecat / LangGraph) for high-stakes flows like payments, identity verification, EHR queries. Tool-calling, RAG over your knowledge base, custom guardrails, fallback chains, and hard cut-overs to humans — all configurable per call type.
