I will build ai voice agent, ai receptionist, and calling bot with vapi ai or retell ai


About this gig
Every missed call is a customer choosing your competitor. Every cold lead, every caller on hold that's revenue walking out the door.
A human receptionist can't work 24/7, can't take five calls at once, and costs a full salary. That's the problem most businesses never fix.
I solve it with a custom AI voice agent (Vapi AI & Retell AI) that answers instantly, sounds human, and handles interruptions whether it's an AI receptionist catching every inbound call 24/7, or an outbound caller qualifying leads and booking appointments.

FAQ
What's the difference between your AI voice agent and a regular chatbot or IVR menu?
A chatbot only handles text, and an IVR just routes calls with rigid menus. My AI voice agents (Vapi AI / Retell AI) hold real, natural conversations, understanding context, handling interruptions, and responding in under a second, so callers feel like they're talking to a real receptionist.
What is the difference between Vapi AI and Retell AI, and which should I choose?
Both are top-tier for low-latency conversational bots. Retell AI is amazing for natural pacing and fast deployment. Vapi AI offers deep customizability for advanced workflows. I will recommend the best one for your specific AI voice agent goals
Can the AI voice agent handle outbound cold calling and book appointments automatically?
Yes. I build outbound AI calling bots that qualify leads, handle objections, and book appointments live into Calendly or Google Calendar during the call, no manual follow-up needed. It works alongside inbound AI receptionist setups for full call coverage.
Will the AI receptionist integrate with my CRM or existing tools?
Yes, I connect your voice agent to GoHighLevel, HubSpot, Salesforce, or Google Sheets using Make.com, Zapier, or n8n for more complex, self-hosted workflows. Every call can trigger automatic lead updates, SMS/email follow-ups, and calendar bookings in your existing stack.
Will callers be able to tell they are talking to an AI?
My goal is for them not to. I fine-tune tone, pacing, and interruption-handling so the agent sounds naturally human, and I optimize latency so responses feel instant, not robotic. Every build goes through real-call testing before delivery to confirm it holds up in live conversation.
What happens if I am not satisfied with the AI voice agent after it is built?
You are covered by my guarantee: if you are not satisfied during testing, I revise it for free. If it still does not meet spec before final delivery, you get a full refund. There is no risk in trying this.
How long does it take to build and launch a custom AI voice agent or receptionist?
Most builds take 5 to 14 days depending on complexity, persona design, call flow, CRM integrations, and testing. I will confirm an exact timeline once I understand your use case, inbound receptionist, outbound calling bot, or both, during our initial discussion.
