AI voice agents that answer real calls for real businesses
Production voice agents on Twilio and the OpenAI Realtime API — not voicemail-to-text. Built and live in 7 weeks for a UK business.
A voice agent is only useful if it holds a real conversation at natural speed and hands you something you can act on. We built NeverMissACall Pro for a UK client: it answers every forwarded call around the clock on a dedicated UK number, and turns each one into a qualified lead with a transcript and a summary in the dashboard.
What's included
- Real-time conversation over Twilio and the OpenAI Realtime API
- A dedicated phone number with call forwarding from your existing line
- Transcripts, summaries and lead qualification in a dashboard
- Self-serve sign-up, plans and billing if you are selling it on
How the work runs
Call flow design
What the agent needs to ask, what it must never say, and when it should hand off to a human.
Build and voice tuning
The real-time pipeline, the telephony integration, and iterating on the voice until it sounds like your business.
Launch
Porting or forwarding numbers, going live, and tuning on real calls in the first weeks.
Across the six projects on this site where we tracked phases, discovery to launch ran 8 to 12 weeks.

Common questions
How fast can a voice agent go live?
NeverMissACall Pro went from idea to production in 7 weeks, including the dashboard, the billing API and the real-time voice system.
Is this just voicemail transcription?
No. The agent holds a real-time conversation over the OpenAI Realtime API rather than recording a message and transcribing it afterwards, so the caller gets answers during the call.
Can it be sold on to my own customers?
Yes. NeverMissACall Pro ships with self-serve sign-up and minute-based plans from £39 a month, built for sole traders.
