I will develop ai cold calling agent and outbound voice bot with vapi retell ai
Dominik Richter
About this gig
Most sales teams waste hours on cold calls that go nowhere.
I build AI outbound calling agents that dial leads, handle objections, qualify prospects and book appointments automatically, 24/7, without a human on the line.
Using VAPI or Retell AI, I set up voice bots that sound natural, follow your script and connect to your CRM or calendar the moment a lead is ready.
What you get:
- Custom AI voice agent built on VAPI or Retell AI
- Your sales script loaded and tested
- Call flow with objection handling and fallback logic
- Calendar booking or CRM handoff on qualified leads
- Phone number setup and carrier connection
- Full test run before delivery
What this does for your business:
- Replaces repetitive cold call work with an agent that never stops
- Qualifies leads before your team ever picks up the phone
- Books meetings directly into your calendar without human effort
- Scales to hundreds of calls a day at a fraction of the cost
Works for real estate, insurance, solar, SaaS, recruitment and any business that runs outbound sales.
Send me your use case and I'll tell you exactly what to build.

Your business loses money every time a call goes unanswered, a lead doesn't hear back, or your website fails to hold attention past 3 seconds.

FAQ
What is the difference between VAPI and Retell AI?
Both are strong platforms for AI voice agents. VAPI gives more flexibility for complex call flows and API integrations. Retell AI is faster to deploy and very strong on voice quality. I'll recommend the right one based on your use case once you share your project details.
Do I need my own VAPI or Retell AI account?
Yes. You'll need an account on whichever platform we use, both have free trials to get started. I handle all the setup and configuration inside your account so you own everything after delivery.
Can this connect to my CRM or GoHighLevel?
Yes. CRM integration is included in the Premium packages. I connect the agent to GoHighLevel, HubSpot, Airtable or a webhook endpoint so every call result is logged and leads are routed automatically.
Will the AI voice sound natural or robotic?
It sounds natural. I use premium voice models available on VAPI and Retell AI that pass as human in most calls. You can also pick a voice from a library or clone a custom one if needed, I'll guide you through it.
How many calls can this agent handle at once?
That depends on your phone carrier plan and the platform tier you're on. The agent itself has no cap, it can run parallel calls. I'll advise on the right setup for your expected call volume during the project.
