I will build an ai voice agent that answers your business calls
Andrei S
About this gig
Your phone rings and nobody picks up. That call goes to a competitor.
I build a voice agent that actually answers: a real phone number, sub-second response, live transcription, and correct behaviour when the caller interrupts mid-sentence. It books appointments, qualifies leads, or answers from your own material - and it hands over to a human the moment the call needs one.
Most sellers offer a chatbot with text-to-speech bolted on. That is not the same thing. The four hard parts are latency, interruption handling, transcription and clean handover, and you can judge all four in a 30-second phone call.
WHAT YOU GET
- A live test number you can call before final delivery
- The agent on your own account, so you own it
- Call transcripts and a handover rule you control
- Written setup notes, so you are not locked to me
RUNNING COSTS: you pay telephony and AI usage on your own account, typically $0.10-0.20 per minute of call. I do not resell it and I do not mark it up. Message me your call volume and I will size it before you order.

FAQ
Can I hear one before I pay?
Yes - message me and I will give you a number to call, before you order anything. And every package includes a test number of your own before final delivery, so you approve it by calling it rather than by reading a description.
What does the cheapest package actually give me?
A working agent on your line that answers the calls you miss, takes the caller's name, number and reason, and emails you the summary. It is small on purpose, but it earns its keep on its own one recovered call usually pays for it.
What does it cost to run after you deliver it?
Roughly $0.10-0.20 per minute of call, paid by you directly to the telephony and AI providers on your own accounts. I do not resell minutes or mark them up. A 3-minute call costs about 40 cents
Which languages does it handle?
English and Romanian are what I test to production quality. Most major European languages work well. Tell me your language before ordering and I will test a sample voice for you first.
What happens when the caller asks something it cannot handle?
It says so and transfers to a human, with a written summary of the call so far. It never invents an answer. You set the handover rule and you can change it afterwards.
Do I own it, or am I tied to you?
You own it. It runs on your accounts, with your keys, and you get written setup notes. If you want to move to another developer, nothing stops you.
