FAQ — Hiring LiveKit Developers
Q:How much does it cost to hire a dedicated LiveKit developer from CelloIP?
Pricing depends on the role, seniority and engagement length — share your requirements and we will send a tailored proposal. Engagements typically cost well below comparable US agencies.
Q:Do CelloIP LiveKit developers also know Asterisk and FreeSWITCH?
Yes. CelloIP's LiveKit engineers have a deep VoIP background. They understand Asterisk PJSIP trunks, FreeSWITCH mod_sofia SIP gateways, and Kamailio/OpenSIPS routing — all required for production LiveKit SIP integration. This is a differentiator vs generic WebRTC freelancers who lack telephony expertise.
Q:Can a CelloIP LiveKit developer build with both LiveKit Cloud and self-hosted LiveKit?
Yes. CelloIP engineers deploy on both LiveKit Cloud (managed) and self-hosted (Docker Compose and Kubernetes Helm chart). Self-hosted deployments include coturn TURN server, Redis HA, TLS certificate management, ingress/egress pipeline configuration, and Prometheus + Grafana monitoring.
Q:Which AI providers can CelloIP LiveKit developers integrate?
All major providers in the LiveKit ecosystem: STT — Deepgram Nova-2, OpenAI Whisper, AssemblyAI, Azure Speech; LLM — OpenAI GPT-4o, Anthropic Claude 3.5, Google Gemini, self-hosted LLaMA 3/Mistral via Ollama; TTS — ElevenLabs, Cartesia Sonic, OpenAI TTS, Amazon Polly. For GDPR/HIPAA requirements, CelloIP can build fully self-hosted pipelines with open-source alternatives.
Q:How quickly can a LiveKit voice agent project be delivered?
A basic LiveKit voice agent (single intent, SIP trunk, LiveKit Cloud) can be delivered in 2–3 weeks. A production system with self-hosted K8s infrastructure, multi-intent NLU, CRM integration, Asterisk bridge, and human handoff routing typically takes 6–16 weeks depending on scope. CelloIP provides a fixed-scope estimate after an initial architecture session.
Q:Can CelloIP provide a full LiveKit team — not just one developer?
Yes. CelloIP can staff a LiveKit pod: a senior voice AI architect, a SIP/telephony integration engineer, a frontend React/Flutter developer, and a DevOps engineer. Full teams are on monthly retainer and coordinated by a CelloIP account manager.
