An AI call answering service, built and run in-house

AllCalls is ours. It is a Build Bros product rather than a client project, which is why it sits here with a note saying so: we built it, we run it, and we pay for it when it goes wrong at two in the morning.

The problem it exists for is the oldest one in a small business. The phone rings while you are up a ladder, in with a client or showing somebody round a flat, you cannot get to it in time, and the caller either hangs up or rings the next number on their list. Voicemail does not fix that, because most people will not leave one.

What it actually does

The business keeps its existing number and sets a divert, so calls arrive at AllCalls when the line is busy, unanswered or out of hours. The assistant answers in the business's own name, has a real conversation with the caller, and finds out who they are, what number to ring them back on and what they want. The moment the call ends, the business gets the details and a written transcript.

What it refuses to do is as deliberate as what it does. It does not guess at prices or dates: it answers only from the questions and answers the business has written for it, and otherwise says somebody will call back. It does not book appointments. It does not put people on hold or try to transfer them. If a caller asks whether they are talking to an AI, it says yes.

Urgent calls, and what counts as urgent

A gas leak is not a message to read in the morning. Each business writes its own rules for what is urgent on its line, and a call that matches them is flagged and the notification goes out immediately rather than waiting its turn, with the genuine emergencies pointed at 999 rather than at a callback. The caller is still not transferred: nothing about an urgent call puts a human on the line, and the page does not pretend otherwise.

Twelve pages, one for each kind of caller

What a plumber's callers ring about is not what a letting agent's callers ring about, so the site does not have one page with a list of industries on it. It has a page each for plumbers, electricians, builders, roofers, heating and gas engineers, locksmiths, solicitors, letting agents, removals, pet services, small businesses and trades in general, every one written for that reader. The page is honest about why: what changes between them is the configuration the business writes, not the software underneath.

The rest of the build

Alongside the marketing site there is a demo line anybody can ring to hear it before buying, a published pricing page, an FAQ covering call divert on each of the main UK networks, a blog, and a customer sign-in where the call log lives. Calls are reviewed and marked as handled there, so a busy morning does not end with nobody sure who has been rung back. No call audio is recorded at all; the written transcript is the record.
