Production voice AI, engineered like infrastructure
I engineer AI voice agents that run real phone lines in production: real-time voice pipelines on your numbers, connected to your CRM, calendar, helpdesk and payment flows, governed by your rules. As co-founder of miniflo, I build, ship and operate these systems for businesses in the UK and India, and I take on projects worldwide. Every agent ships with a spec sheet, a test suite and monitoring, and goes live in four weeks.
- Up to 20concurrent calls per agent
- 40+languages, replying in the caller's own
- 24/7no queues, no voicemail
- 4 weeksfrom survey to production
What goes into every voice agent
Real-time voice pipeline
Streaming speech recognition, LLM reasoning and natural speech synthesis on your phone lines, tuned for low latency, natural turn-taking and callers who interrupt.
Telephony and channels
Inbound and outbound calling on Twilio, Exotel and other carriers, rented or existing numbers, plus WhatsApp and SMS follow-ups such as payment links.
Tool calling into your systems
Live actions during the call: book into calendars, create and update CRM and helpdesk records, check orders, policies or loan data, and write back every outcome.
Guardrails and compliance
Verification flows, policy rules, calling hours and retry limits, approvals for sensitive actions and a full audit log of every call.
Human hand-off
Warm transfers to your team with a written summary whenever the caller is upset, the case is sensitive or the agent is unsure.
Test suites and monitoring
Every agent is tested on real cases before launch, then monitored with transcripts, recordings, outcome dashboards and the ROI baseline it was built against.
12 production agent types
- Inbound call receptionist: answers 24/7, qualifies callers, books appointments
- Outbound calling: works through CRM lists on schedule and logs every outcome
- Support & FAQ agent: answers from your docs and creates helpdesk tickets
- Insurance renewals: calls ahead of renewal and sends renewal links
- EMI reminders: confirms instalments, shares payment links, logs promises to pay
- Banking & card servicing: balances, transactions and card requests within your policies
- Order tracking & returns: live delivery status, returns and refund checks
- Shopping & cart recovery: product help and abandoned-cart call-backs
- Service alerts & routing: routes service calls and broadcasts outage alerts
- Internal service desk: staff IT and ops questions, tickets logged by voice
- Patient appointments: bookings, reminders and post-care follow-ups
- Clinical documentation: spoken notes and calls turned into structured records

Questions
What is an AI voice agent?
An AI voice agent is software that answers and makes phone calls in a natural voice. It understands the caller, follows your rules, takes actions such as booking an appointment or updating a record, and hands complex calls to your team.
How many calls can an AI voice agent handle at once?
Each agent handles up to 20 simultaneous calls, around the clock, so there are no queues at peak times.
Which phone systems and tools does it work with?
Carriers and contact-centre platforms such as Twilio, Exotel, Genesys and Amazon Connect, rented or existing numbers, WhatsApp and SMS, and business tools including HubSpot, Salesforce, Zendesk, Freshdesk and Google Calendar.
What happens when the agent is unsure?
It never guesses on anything that matters. Guardrails define what it may do, sensitive or unclear cases go to a person with a written summary, and every call is logged for review.
How long does it take to launch an AI voice agent?
Four weeks: survey, spec, build and commission. You see a working agent at the end of week three and sign off only when it meets the agreed numbers.
Do you build voice agents for clients outside India?
Yes. I work remotely with clients worldwide, and the agents speak 40+ languages.
