Lift emergencies 24/7: handling them without an external call centre
If you maintain lifts, the emergency line can never be busy: a trapped person doesn't wait. Most companies solve it with an expensive external call centre or the on-call engineer's mobile. There's a third way: an AI agent that answers every call, day and night, and gets it to the right person with the details already gathered.
Not every 3am call is the same
A trapped person is an emergency that must reach the on-call engineer immediately. A stopped lift with nobody inside can wait until morning. An admin query shouldn't wake anyone. The problem is that, with no filter in front of them, all three calls ring the same mobile, at the same hour, sounding equally urgent.
An AI voice agent answers on the first ring and asks the key questions ("is anyone inside?", "which building?", "which unit number?"). When the answer matches a case you wrote into the protocol yourself, it routes straight to the on-call engineer with everything gathered; the rest is logged for the morning.
It is worth being precise about what it does and does not do. The agent recognises written cases and routes: it does not assess severity, does not set priorities and does not replace the engineer's judgement, who still decides what gets attended and in what order. The distinction is not cosmetic. A system that scored emergencies to decide who gets sent first would fall under Annex III of the EU AI Act, with every obligation that brings.
| External call centre | On-call engineer's mobile | AI agent + routing | |
|---|---|---|---|
| Who answers at 3am | An operator who doesn't know your units | The engineer, asleep | The agent, on the first ring |
| What reaches the engineer | An incomplete note; usually needs a callback | Whatever they remember of the call | Building, unit and whether anyone is inside, in writing |
| Cost | Per call or a flat fee | On-call hours and staff turnover | Monthly fee based on volume |
| Log for inspections | Depends on the provider | None, unless someone writes it down | Automatic, with timestamp and transcript |
| Who decides urgency | The operator | The engineer | The engineer: the agent only collects and routes |
What covering the on-call rota costs you today
An external call centre charges per call or per retainer, and even then it only takes a message: the engineer has to call back to understand the issue. And when the rota lands on an engineer's mobile, you pay availability hours and accumulate burnout and turnover.
Run the same maths we propose for missed calls: faults per month × cost of each manual handling. The figure usually justifies automation many times over.
Compliance and traceability built in
Every fault is logged with time, building, unit and a transcript of the conversation: the traceability inspections and insurers ask for, with nobody filling in forms by hand.
And because the system escalates to a person when it detects a real emergency, the on-call engineer only gets the calls that truly need their hands.
Frequently asked questions
Does the agent decide whether a call is urgent?
No, and that is deliberate. It recognises the cases you wrote into your own protocol and routes them; assessing severity and deciding the order of response stays with the on-call engineer. A system that scored emergencies to decide who gets sent first would fall under Annex III of the EU AI Act, with every obligation that brings.
What if the caller doesn't know the unit number?
It asks another way: address, floor, or what is written inside the car. And if that still fails, it routes anyway. When there is any doubt with a person inside, it always goes to a human.
Can it connect to our notice system?
Yes, as long as it has an API or accepts structured email. Where neither exists, the notice arrives with full context in a channel you already watch (email, WhatsApp or Slack) and the log is kept just the same.
Does it say it is an AI?
Yes, in the first message of every call, along with the fact that the conversation is transcribed. Article 50 of Regulation (EU) 2024/1689 has required it since 2 August 2026, and we carry it in the contract as an obligation of our own.
