FAQ
What VPS specifications do I need to prepare?
A clean Ubuntu 22.04 or 24.04 LTS server with at least 4 GB RAM and 2 vCPUs works best. Reliable providers include Hetzner, Hostinger, Contabo, AWS, or DigitalOcean. I will provide the exact setup checklist upon order.
Which API keys and telephony providers are required?
You will need accounts and API keys for your preferred LLM (Google Gemini or Groq), TTS voice provider (Rumik, Cartesia, or ElevenLabs), and SIP carrier (VoBiz, Twilio, or Telnyx). All credentials remain 100% private on your own VPS.
How is this better than platforms like Bland AI, Vapi, or Retell?
Closed platforms charge $0.15 to $0.30 per minute plus recurring monthly fees. With a self-hosted voice agent stack, you own your data, eliminate vendor lock-in, and only pay raw provider costs (typically averaging $0.02 to $0.04 per minute).
Can the AI voice agent check availability and book calendar appointments?
Yes. The Standard and Premium tiers include live Google Calendar integration. The voice agent queries your live schedule during the call, prevents double bookings, and places confirmed appointments directly into your calendar.
Do you place real live phone test calls before delivery?
Yes. Handover acceptance includes dial-testing your live system to verify sub-second conversational latency, natural interruption handling, audio fidelity, and tool-calling execution before delivery is finalized.
