AI phone agent

An AI phone agent that answers your business calls

Connect a phone number to the same assistant that runs your website chat. Callers talk normally and can interrupt, get answers from your knowledge and book an appointment, and every call arrives in your inbox as a written conversation.

Why an AI receptionist, and where it stops

Calls come at the worst moments: in the middle of an appointment, after hours, three at once. An AI receptionist picks up every one, answers the routine questions (opening hours, prices, directions, what a service includes), takes a booking and leaves you a written record. In FlowSentric this is not a separate product with separate content. It is your website assistant with a phone line, using the same knowledge, the same instructions and the same privacy settings. You can also give one of your agents its own line.

In real-time mode, which is the default, the caller's audio streams to FlowSentric, is transcribed by our own speech recognition, and the answer is read out sentence by sentence by our own voice service while the rest is still being written. When the caller starts talking, the assistant stops at once and listens; a cough or speakerphone echo does not count. If the real-time services are unavailable, the call is answered in classic turn-based mode, where the telephony provider handles the speech, rather than being dropped.

Answers on the phone are short by design: one or two spoken sentences, numbers and times said the way a person says them, no lists and no web addresses. If nobody speaks, the assistant asks whether the caller is still there and then says goodbye. You set the greeting, the language, the voice and the longest call you allow, and every turn runs on your plan and token budget like any chat message.

What it does not do today: it answers incoming calls only, it does not place outgoing calls, and it cannot forward a caller to a colleague's phone. Your team sees the transcript in the inbox and calls back. A widget that requires sign-in never answers calls, because a caller's identity cannot be verified on the phone.

What it does for you

01

A conversation, not a phone menu

No “press 1”. Callers say what they need in their own words, can interrupt mid-sentence, and the first words of an answer play while the rest is still being written.

02

Bookings while on the line

With booking switched on, the assistant finds a free slot and books it during the call, through the same engine and rules as your booking page.

03

Every call written down

Each call is stored as a conversation in your inbox. When the caller hangs up, the same end-of-conversation steps run as for a chat: lead scoring, a workflow, a webhook.

How it works

01Get a number from one of the two supported telephony providers; the account and its call charges stay yours.
02In the widget's phone settings, or an agent's phone calls, enter the number and credentials, then pick language, voice, greeting and the longest call.
03Paste the webhook address FlowSentric shows into your provider's number settings.
04Call the number: the assistant answers, and the conversation appears in your inbox.

Frequently asked questions

What is an AI phone agent?
A program that answers your business number, understands what the caller says, replies in a natural voice and takes simple actions such as booking an appointment. In FlowSentric it is the same assistant as your website chat, with a phone line attached.
Can callers interrupt the AI?
Yes. In real-time mode, about a quarter of a second of caller speech makes the assistant stop talking at once, and what the caller said becomes the next turn. Coughs and speakerphone echo are ignored.
Can it book appointments during the call?
Yes, when booking is switched on for the assistant. It uses the same booking engine as your booking page, so working hours, buffers and existing entries apply in the same way.
Can it transfer a caller to a person?
Not today. The call is written into your inbox as a conversation, with what the caller asked, so a colleague can call back with the full picture.
Where is the caller's speech processed?
In real-time mode, speech recognition and the voice run on our own servers. In the classic fallback mode, the telephony provider handles the speech. The answer itself is written by the model you chose for the assistant; pick an EU-hosted model if that matters to you, and Privacy Guard masks personal data before the model sees it.
Which plan includes phone calls?
The Business and Custom packages. Call charges come from your telephony provider. You can start on the free plan at €0 and add phone calls when your package includes them; see pricing.
