About this gig
Are missed calls costing you revenue? I build 24/7 Inbound AI Voice Receptionists using Vapi AI & Retell AI that answer calls instantly, answer FAQs, and book appointments in real time.
Ideal for clinics, law firms, real estate, and service businesses needing human-sounding AI phone agents.

NOTE ON RUNNING COSTS:
You will use your own accounts/API keys (Vapi, Retell, Twilio, OpenAI). Telecom fees (~$0.08$0.15/min) are paid directly to those platforms. I will assist with setup during delivery.

FAQ
Will the AI voice receptionist sound robotic during phone calls?
Not at all. We integrate ultra-low latency voice models through Retell AI, Vapi, ElevenLabs, and Deepgram. Response times are usually under 800ms with natural breathing pauses, dynamic inflections, and human-like conversational flow.
How does the AI book appointments on my calendar live during a call?
The AI voice agent uses real-time tool calling connected to your calendar (Google Calendar, Cal.com, or GoHighLevel) via webhooks or n8n. It checks your live availability, offers available slots to the caller, and confirms the booking immediately on the call.
Do I need my own third-party accounts and API keys?
Yes. To ensure your business phone numbers, caller data, and workflows remain 100% under your ownership, you will use your own accounts (Vapi, Retell AI, Twilio, OpenAI). Telecom and AI usage costs (around $0.08–$0.15/minute) are paid directly to those platforms without markups.
Can the AI receptionist transfer urgent calls to my personal mobile phone?
Yes! We set up conditional logic so that if a caller requests a human, mentions an emergency, or meets specific criteria, the AI seamlessly transfers the live call directly to your personal or team phone line.
Can the AI voice agent answer specific questions about my business?
es. We configure a custom Knowledge Base (RAG) using your website content, PDFs, or service guidelines so the AI accurately answers FAQs regarding your pricing, office location, business hours, and policies.
What happens after a call ends?
Automatically via n8n/webhooks, the system logs the full call transcript and audio recording, sends an instant SMS/email confirmation to the customer, and updates your CRM (HubSpot, GoHighLevel, Salesforce, or Google Sheets).

Really happy with this.I was treated me like a real client should be treated. The script fits my shop perfectly, it sounds friendly and laid back, just like how we talk to customers. The setup guide was easy to follow even for someone like me who’s not into tech. She also explained the monthly costs...
