I will build ai voice caller ai calling agents across vapi, retell, bland, synthflow


About this gig
Missed calls rarely leave voicemails. They call your competitor next.
We are an AI agency building an ai voice caller that answers, qualifies and books appointments 24/7, inbound and outbound, in a natural human-sounding voice.
the platform matters less than the setup. AI calling agents usually fail on weak prompts, no calendar sync or no human handoff. We build on Vapi, Retell AI, Bland AI and Synthflow and choose the one that fits your call flow and budget.
What you get:
- AI receptionist, ai voice assistant and ai phone agent for inbound calls
- AI cold calling and lead qualification agent
- Appointment booking synced to calendar and CRM
- n8n, GoHighLevel, Make, Twilio, ElevenLabs setup
- Call transfer, SMS follow-up, summaries, transcripts
Running a clinic, agency, real estate or home service business? Staff costs, after-hours calls and slow lead follow-up add up fast. We get it, and we build around it.
Other businesses are already answering every call with ai. Message us before ordering and we will map your call flow for free.

FAQ
Which platform should I choose: Vapi, Retell, Bland or Synthflow?
It depends on your call flow. I use Vapi for custom logic, Retell AI for receptionist-style inbound, Bland AI for high-volume outbound and Synthflow for no-code builds. Tell me your use case and I will recommend the best fit for your ai voice caller.
Will my ai voice caller sound robotic or make things up?
No. I use natural ElevenLabs-style voices, tight prompts and a knowledge base so the agent answers only from your business info. If it is unsure, it transfers to a human or takes a message. I run real test calls before handover.
Can it book into my calendar and update my CRM?
Yes. The ai calling agent checks live availability, books into Google Calendar, Calendly or GoHighLevel, then pushes name, number and call notes to your CRM via n8n, Make or webhooks. I need your calendar and CRM access after you order.
Can you build ai cold calling for outbound lead qualification?
Yes, outbound ai cold calling and lead qualification are in Standard and Premium. You must call only leads you have permission to contact and follow your local calling and consent laws. I set up opt-out handling and a clear AI disclosure line.
What are the call costs and platform fees?
My price covers the build. Vapi, Retell, Bland or Synthflow bill you separately for usage, usually per minute, plus your phone number (Twilio) and voice (ElevenLabs). I give you a simple cost estimate before we start so there are no surprises.
Do I own the agent, and what happens after delivery?
You own the agent, prompts and workflows, built in your own platform accounts. I hand over a walkthrough video and call summaries so your team can manage it. Fine-tuning after launch is included in Premium or available as an extra.
