Notes from building an AI receptionist.

Arun Paul is building Magixis and writes up the research as he goes: what the UK rules require, what vendors actually charge, and which of the numbers this industry quotes survive being traced back to a source. Every post ends with its source list, fetched and checked on the day it went out.

How medical clinics and law firms use AI to automate lead routing

Route on what a caller stated and you are automating admin. Rank by inferred severity and MHRA guidance treats the software as a medical device, because in England triage has a statutory definition. Also inside: the conflict-check order a law firm cannot reverse, and why the five-minute response rule is 2007 vendor data from six companies.

The hidden cost of missed calls: how an AI receptionist pays for itself

The "$126,000 a year" figure everyone quotes is untraceable — one attribution points at a 404. The "62%" figure is from January 2016. We traced both, then priced 19 AI and human answering vendors off their own live pages, and show the twenty-minute method for working out your real number.

AI receptionist for accountants: what the UK rules require

Whether UK practices need one at all, then the rules if you run one: ICAEW guidance, the PCRT's January 2026 AI update, the ICO's position on call recording and DPIAs, and the Article 22A–D rewrite in force since 5 February 2026. Quoted from the instruments rather than paraphrased.

Quoted in the post
"In the vast majority of cases, the use of AI will involve a type of processing likely to result in a high risk to individuals' rights and freedoms, and will therefore trigger the legal requirement for you to undertake a DPIA."
Method
01

Dated sources on every post

Each post ends with its full source list, fetched and checked on the day it goes out. Prices carry the date they were retrieved.

02

Untraceable numbers get flagged

Figures that can't be traced to a real study, like the "$126,000 a year" missed-call statistic, are labelled as claims and never used as evidence.

03

One author, no agency

Arun Paul researches and writes every post himself, in the course of building the product.
