I will build a voice AI agent for inbound and outbound phone calls

About this service

Let an AI answer your phones and make calls for you. I build voice AI agents using Vapi, Retell, or Twilio that handle bookings, qualify leads, answer FAQs, and follow up, sounding remarkably human on the line.

  • Natural-sounding voice agent with your chosen persona
  • Inbound call answering, routing, and FAQ handling
  • Outbound lead qualification and appointment reminders
  • Calendar booking and CRM logging integration
  • Call transcripts, recordings, and live human transfer

Why me? I tune latency, interruption handling, and prompts so conversations flow naturally instead of feeling like a clunky IVR. I test on real calls before going live.

Share your use case and call volume, and I'll recommend the right platform and scope. Let's give your business a tireless voice team.
