AI PBX that talks instead of a phone menu

What an AI PBX actually is

A PBX is a phone system. In a small Greek shop it is a beige box on the wall, a strip of tape on the handset, and a night switch that someone forgets. 1 sales. 2 accounts. 3 the warehouse. Hash for the operator, who is the same person as sales.

People hang up in the menu. Tourists cannot follow the Greek recording. Regulars mash zero until something happens. After closing the whole tree dumps onto a mobile that is face-down in a van. The hunt group rings the empty desk, then the mobile, then dies.

An AI PBX replaces that system. Not with another metal box from the telecoms shop. Not with a rewire. With a spoken question — who do you need — and then a route you wrote, or a note if the extension is empty.

It is not the craft of greeting. A receptionist is a person at a desk. It is not the write-up at 18:30. It is not a clipboard of twelve names. It is not a room of headsets. It is the tree. The tree becomes sentences. The number on the door does not change.

The beige box and the menu

The box was a purchase. It felt like infrastructure. It is now a habit. The sticker has faded. The recording is still last year’s hours. Press 1 still goes to a desk that is empty between two and half past five. Press 2 still goes to accounts, who are one person with a door shut, who do not pick up while they are in a file.

A menu is a test the caller did not ask to sit. In this country a lot of the people who ring a shop number are standing in a street, or in a car park, or they are a visitor who can say the business name and nothing else. DTMF is not a service to them. It is a locked door with instructions in a language they do not use.

The AI PBX asks who they need, in the language they rang in. Shop. Accounts. Warehouse. Kostas. A time. That is the whole tree, spoken. If you have two places, the first question is which door, by name of the street, not by a key.

Do not rebuild the menu as a longer spoken menu. “Say one for sales, say two for accounts” is the same box with manners. Ask the job. Then route.

Hunt groups, night service, and a mobile in a van

A hunt group is a hope. Ring the desk. If not, ring the mobile. If not, voicemail. The desk is empty. The mobile is in a toolbox. The voicemail is in Greek. The caller has already gone.

Write the next step as a step, not as a hope. If the desk does not pick up: try this number, between these hours. If that fails: take a name, take the thing in their words, promise a morning callback, send the SMS. Dying on the second ring-out is the old box.

Night service on the box is usually worse. One switch. The whole tree becomes one mobile. That mobile is doing something else. A dump is not routing. Closed hours are still hours in which people ring — the people who work your opening time, the visitor who did not know you close at two, the courier who will not come back.

Write closed hours as talking hours. The system can say the afternoon hours, take a name, offer a next open slot if the diary allows, and not pretend that a van is an extension.

Through-dial to a person by name is allowed if you named the person and the hours. Through-dial to “anyone in the back” is the shout through the shop, now automated, still a failure if the back is a machine and a pair of occupied hands.

Talking instead of press 1

The replacement for a key is a sentence.

“Who do you need.” Then wait. If they pause, name the places you actually have. Do not name seven departments you do not have. A two-person shop with a seven-branch tree is a box that is lying.

If they know a name, try that number in the hours you wrote. If they know a job — invoice, part, Saturday — map the job to a route. Invoice is accounts. Part is the shop. Saturday is hours, which the system may say without waking anyone.

A tourist who rang in English gets the question in English. A caller who rang in Greek gets it in Greek. The system works in 70+ languages. The recording on the box was one language, sometimes two if someone sat down with a microphone in 2019.

If they say they want a person and they do not care which, that is a receptionist route, not a random extension. Do not punish them with a key they refused to press.

If they have already suffered the old menu this week, say that they do not have to press anything. The dialogue above does that. Week one will be full of people who are still waiting for a key. Teach the system to hear that wait as a question, not as silence to be filled with the tree again.

Keep the number, lose the hardware

The number is the asset. The box is not.

People have the number in their phone from a card in a glove box, from the glass, from a search result, from a WhatsApp that was really a missed call. A project that starts by issuing a new number is a project that trains the street to forget you.

Forwarding is the whole install. Every call, or only the ones the desk did not take. If someone in the shop picks up, the call never leaves and is never charged. The box can stay on the wall as a monument. It does not have to do any more work.

Two shops, two numbers, two trees, two diaries — or one number and a first question that names the streets. A shared number with a key for the other door is how a visitor walks to the wrong shutter in the heat. Spoken names of places beat keys.

When you change Saturday, you change a sentence, not a recording sitting in a box nobody wants to open. When you close for 15 August, you change a sentence. The old hardware kept last year’s feast in its memory because changing the recording needed a password on a faded sticker.

How CITT handles the system

1. The number on the door stays the number on the door. One forwarding rule. No rewire. No new metal.
2. The tree is questions, not keys. Who they need. Which door, if you have two. Then a route you named.
3. An empty extension does not die. Note, next number, morning callback. You write the order.
4. Closed hours talk. Hours, name-take, next open slot if the diary allows. Not a dump to a van.
5. The caller’s language is the menu language — 70+ languages — so a visitor is not examined in Greek DTMF.
6. A time, if one is offered, is checked in the diary and confirmed by SMS. Routing can still book. It must not book from a key.
7. You get the route each call took. Shop, accounts, note, night, wrong door. That is how you see the tree working, or leaking.

What a PBX will not do

It will not be a box you buy. It will not ask them to press 1. It will not dump night calls onto a mobile you cannot reach. It will not rewire the shop. It will not change the published number. It will not be a room of headsets. It will not work your outbound list. It will not sit in Maria’s chair as a personality.

It will not invent an extension you do not have. A three-person business with a nine-branch tree is the old box showing off. Cut the tree until every branch has a real number or a real note.

It will not tell a caller they have reached the other street’s shop unless that is true. Guessing the door is worse than asking the street name.

What a routed call sounds like

The exchange above is the shape. They hit the old menu and froze. They want accounts, an invoice from March. They already lost a night to a van mobile. They are not sure this is the right Georgiou. The system says they do not have to press. It tries accounts. It refuses the dump. It names the street so the wrong door is a spoken fact, not a key.

A good routed call is short and named. Who, which place, what happens if that place is empty. If the transcript is a tour of departments you do not have, the tree is still the old sticker.

“Press 1” should not appear on the tape at all. If week one still contains it, the recording on the box is still in the path. Take it out.

What you set up first

The forwarding rule on the published number. Then the spoken tree: the real places, the real names, the hours each may be tried. Then the next step when an extension is empty. Then closed hours as talking hours, not as a dump.

Write the two doors if you have two. Write August. Write the sentence that they do not have to press anything. Do not import the old sticker as a script.

Listen for people who wait for a key, people who ask if this is the other street, and night calls that still smell like a van. Those three are the old box still running. Turn them into sentences and the hardware can stay on the wall, unplugged from the job.
