A phone system that already knows your business before it rings.
A guest calls and the booking, the orders and every message your team has exchanged are on screen before anybody picks up. The call records itself, transcribes in the language it was held in, and attaches to that person. Start with one number. Scale to queues, call flows and a supervisor floor without changing systems.
The Phone App for Your Business
Numbers, call flows, queues, an AI receptionist, recording, and transcription in the language the call was held in. Their bookings and orders are on screen before you pick up.

ways a supervisor can join a live call
A business number that works from a browser tab.
Calls in and out, voicemail that transcribes itself, and a log that files every call against the person who made it. This is the whole product for a business of one, and it is the floor everything after it is built on.
Everything the call might need, without leaving the call.
Hold it, pass it on, bring somebody in, text them, show them, and write it up before the next one rings. The minute a line is open is the minute a phone system is either helping or in the way.
Consent, before anything is recorded
A consent banner is shown and the answer is recorded with the call, so a jurisdiction that requires notice is handled by the product rather than by remembering to say a sentence.
Warm, blind and attended transfer
Speak to the colleague first and then hand over, or pass the call straight through. The destination can be an extension, a ring group, a voicemail box or an outside number.
Turn a call into a conference
Add people to a dial-in room with a PIN. The moderator can mute a participant, remove one, and start or stop the recording for everybody on it.
Text them the thing you just described
An SMS from the same business number, while the call is still open, so an address or a link arrives before the caller has hung up.
Move to video without redialling
A call that needs showing rather than telling becomes a room. Nobody hangs up and nobody sends an invitation.
Wrap up before the next one rings
A disposition from your own list, notes typed once, and a follow-up time. The agent goes back to available when the wrap-up is done rather than when the call ended.
Play it back
The recording is playable from the call, with its transcript beside it, so a disputed detail is settled by listening rather than by recollection.
Ask for it out loud
Spoken commands dial a number, open the transfer sheet, check voicemail, start a conference or pull up the call log, for the hands that are already holding something else.
That is the phone. Underneath it is the system deciding who gets each call.
Send each call to whoever should answer.
Past one person, Voice is a phone system. Five extension types, ring groups with five strategies for spreading a call across a team, and routing rules that put the call in front of the right person by time of day, caller ID or dialled number.
Five extension types. Each one is a real destination a number, a rule or a call flow can point at.
User
Ext 101A personal line for one team member.
Department
Ext 200Sales, support, or any team group.
Shared Line
Ext 300A reception desk, shared across several people.
Voicemail Box
Ext 900After hours or record-only, with no live agent behind it.
Call Parking
Ext 700Park a call on a shared slot for somebody else to pick up.
The call never hits a dead end.
Every path leads somewhere: a person, a queue, a callback or a voicemail with a transcript. Open any step to see what it decides.
Draw the route, then watch the queue run.
Menus, time splits, ring groups and queues are one drag-and-connect canvas rather than a support ticket. What the canvas produces is a live queue with a wait time, an overflow rule and an answer-rate target you can be held to.
The call flow editor
Drag and connect the steps: greeting, menu, time check, routing, voicemail, SMS, webhook, hangup. No code, which means the office manager changes the routing rather than filing a request for it.
Queues that tell the truth
Estimated wait, position announcements, hold music, priority routing for VIP and returning callers, and an overflow rule that catches a queue nobody is clearing.
What a queue looks like while it is running
Waiting count, average wait, longest hold, agents on the queue and the SLA percentage, per queue, as it happens.
Hang up and keep your place
A caller who does not want to hold asks for a callback instead. The request keeps the number, the name and the time they wanted, and attempts are counted, so nobody is dialled forever and nobody is quietly dropped after one try.
The promise, and every time you missed it
A rule fixes how long a phone may ring, how long a caller may wait and the answer rate you are aiming at. The breach tab is the honest half: each miss with the value it hit, the threshold it broke and when. Nothing is averaged away.
Nobody answered, and that is an event
An unanswered or after-hours call raises a named event carrying the caller, the number, the time and the reason. Rules you wrote decide what happens next, which for most operations is a concierge case opened for callback. Nothing about that path went through a support request.
Listen. Whisper. Barge. Every call monitored in real time.
For a front desk, a reservation line, a support team or a full call centre. The floor shows every active call, every agent's status and every queue as they are. Three monitoring modes let a supervisor coach without the caller knowing, or step into the call when that is what it needs. SLA rules catch a breach before it becomes a complaint, and every call carries a quality score.
Listen
Silent monitoring. The supervisor hears the call. Neither the agent nor the caller knows.
Quality assurance and training.
Whisper
The supervisor speaks to the agent. The caller does not hear.
Real-time coaching during a difficult call.
Barge
The supervisor joins the call. Everyone hears.
Escalation, support, or closing a deal together.
Every agent on this floor is somebody you already hired
The list is the account roster, read from the same member records every other app reads. Hiring somebody gives them an extension, a queue and a status. The day they leave, they leave once, and there is no phone-system directory left to reconcile.
Live Monitor
Every active agent in one grid: available, on call, in wrap-up or offline, with the current call duration and the queue stats beside them.
Live Assist
The caller-context panel on the live call: contact profile, active bookings, recent orders and membership, with their open Desk tickets alongside and Send to Desk in one click.
SLA Management
Targets per queue for maximum wait, maximum ring and answer rate. Breach alerts fire to supervisors and managers as they happen.
Call Quality
MOS, jitter and packet loss scored on every call, so a bad line is a measurement rather than an argument, and the trend is visible over time.
Call Analytics
Volume, average handle time, first-call resolution, peak hours and agent performance, filtered by date range.
Call Tracking
Source attribution on inbound calls: which channel, which campaign and which page produced the call, across four parameters.
Transcription
Recordings transcribed with the speakers labelled, in the language the call was held in, searchable afterwards for review and compliance.
Every call is a row, and the rows add up to an answer.
Volume, handle time, first-call resolution and peak hours are the easy half.
What people are calling about
The reason behind the volume.
Which agent is carrying the queue
Named, not averaged.
Whether the line itself is the problem
Sometimes the answer is the number, not the team.
Per agent, not per team
Calls handled, average handle time and answer rate beside the quality score and acceptance rate stored on each agent. An agent with no calls in the window still appears, because a board that hides an idle seat is not a board.
What people actually call about
Every call is grouped by the service the caller reached, so the reason for the phone ringing is a ranked list rather than an impression. A month where billing questions doubled is visible as a bar, and it is usually the first evidence that something upstream broke.
The read, written out
A plain summary of the window and the recommendations that follow from it, computed from the same aggregate the charts use. No figure appears in the sentence that is not in the table above it.
Why the call sounded like that
MOS, jitter and packet loss scored on every call and tracked as a trend, so a bad line is a measurement somebody can act on rather than an argument between two people who were both there.
Any window, and a file
Today, the week, the month, the quarter, the year, or a number of days you name. What the screen shows, the export gives you, for the board pack that does not open in a browser.
The phone is never unattended.
An answering step that knows the business, holds a short conversation, and brings in a person the moment one is needed. For an operation that cannot afford to miss a call and cannot staff a line around the clock, this is the difference.
A step in the call flow, not a separate product
Drop the answering step wherever the flow needs it: the after-hours branch, the overflow past a queue, or the path a call takes when nobody is on shift. A business-hours gate decides when it is active at all.
Call out to 531 destinations at a published rate.
Outbound calling reaches 531 destinations, each carrying its own per-minute rate in euros and dollars rather than a blended average you have to take on trust.
Latin America
Brazil, Mexico, Colombia, Argentina, Chile, Peru and more, each with its own published rate and dial prefixes rather than one regional average.
Africa
Nigeria, South Africa, Kenya, Ghana, Egypt and more, priced per destination rather than lumped into a single continental rate.
Europe
UK, Germany, France, Spain, Netherlands and more, with mobile and landline priced separately where the carriers price them separately.
Asia-Pacific
Australia, India, Japan, Singapore, Philippines and more, each carrying the prefixes the rate actually covers.
Point a number wherever you want it.
What a number is, where it goes, how it gets here, and what one seat entitles you to provision.
Number Pool
Every number on the account in one list, each pointed at an extension, a ring group or a call flow, and repointed without touching anything downstream of it.
Four Kinds
Local, toll-free, mobile and short code, recorded per number so a rule can treat the toll-free line differently from the mobile one.
Number Porting
Bring the numbers you already publish, through the porting wizard, tracked from submission to carrier confirmation.
Requests and Status
A request records the country, the area code and the kind you asked for, and stays visible with its status until the number is live.
One Seat, One Number
A seat carries the right to provision one number. Ten seats provision ten numbers, and a solo operator who wants a local line and a toll-free line buys two seats.
Every Rate Published
Each destination carries its own per-minute price in euros and dollars, the dial prefixes that price covers, and mobile priced apart from landline wherever the carriers price them apart.
Search Before You Ask
Available numbers are searchable by country and area code before a request is raised, so you choose the number rather than accept whichever one arrives.
Vanity Numbers
Search by the word you want the keypad to spell. A number a customer can remember without reading it off a screen is worth more than one that sorts well.
Local, toll-free, mobile and short code. All in one place.
Every number your business answers on, what it is for, and whether the AI receptionist picks up. One more number does not mean a second system.
Call from a number that looks like it is next door.
A local number matching the area you are dialling raises the odds of being answered. Where the call has to stay private, a masking number connects two people without either seeing the other. And a voicemail recorded once can be dropped into a ringing line rather than said again.
Every other phone system integrates. This one shares the database.
A connector syncs a subset of your data on a delay and breaks when either product updates. Voice reads and writes the same rows as the rest of the account, so there is nothing to sync and nothing to fetch.
The record is open before you say hello.
A number the account has seen before arrives with its person attached: what they booked, what they ordered, what they are owed and what is still open on them. Nothing was typed into a second system to put it there, and nothing was fetched from one.
Search a name and get every call, every email, every message.
A standalone phone system logs calls.
It cannot reach the other channels
The emails, the chats and the video meetings live in other products.
So the history is never one history
The call sits apart from everything else that person did.
Link holds one chronological timeline
Every message with one person, in the order they happened.
The recording slots in beside the rest
A Voice recording and its transcript sit next to the chat thread and the signed agreement.
Mail, Inbox and Live file the same way
The email thread on the same contact, a missed call in the same queue as a web chat, the video meeting with its own recording and transcript.
No nightly reconcile
Every channel writes to the same timeline as it happens.
Out loud is as searchable as in writing
Searching a person's name returns both.
The follow-up starts from what was said, not from somebody’s memory of it.
Turning a call into a ticket somewhere else means copying a summary between two products. Here each of these is one action that writes to the same rows the receiving app already reads.
Send to Desk, during or after the call
The ticket carries the caller, the summary and the recording link. Support picks up from the transcript rather than from a note somebody meant to write.
Know which page, which campaign and which screen produced the call.
Call tracking is usually a third product bolted between a phone system and a marketing platform. Here the marketing tools and the phone system already write to the same records, so attribution is a column rather than a vendor.
The call arrives carrying its source
Source, medium, campaign and content attach to every inbound call on a tracked number.
It stays on the contact afterwards
So the report that says which campaign produced revenue is reading calls rather than guessing at them.
The number on the website
The phone number on a Calisto site is a Voice number, and a click-to-call from the page routes through Voice with the caller record attached.
The number in a campaign
A number in an email campaign carries its source with it. The call log shows which campaign, which send and which segment produced the call.
The button on a kiosk or an app
A "call us" button on a self-service kiosk or a branded app connects through Voice, on the same number and into the same queues.
Four attribution parameters
Source, medium, campaign and content attach to every inbound call on a tracked number, and stay on the record after the call ends.
Read what was said without listening to it again.
Recordings transcribe with the speakers labelled, in the language the call was actually held in, with a sentiment read on each one. The note nobody would have written is written anyway, and it is attached to the person who called.
Where Voice touches everything else.
7 of these 7 connections are in your plan today. The rest stay visible so you know the instrument is there before you need it.
Inbox
A caller who also wrote to you is one person with one history.
The follow-up you send after the call sits on the same record as the call itself.
Live
A website chat that needs a voice escalates to a call without the visitor re-explaining it.
Orbit
The caller’s record is assembled from the apps that wrote it, not from a phone-system contact list.
Link
The call, its outcome and its recording save to the contact timeline beside every other channel.
Equipo
A call the team needs to discuss moves to an internal channel with the recording attached.
Identity
A caller who has to be verified before you act runs a check against the record on screen.
No setup cost. Pay when you start using.
A phone system for the whole team.
Calisto Voice
Business phone system.
Works better together
Voice runs on its own. Every Interact app it sits beside is priced on its own too.
Each seat entitles one phone number to be provisioned, and inbound calls to your own numbers are carried by the seat price. Outbound minutes bill at the published rate for the destination dialled.

Questions about Calisto Voice
No. It is a softphone in the browser, with call flows and queues behind it. The hardware requirement is a headset.
The caller bookings, orders and history are on screen before you answer, because Voice reads the same contact record the rest of the account does.
Yes. There is a full-screen mobile dialler with its own keypad, recents, contacts and voicemail, so the business line travels without anybody handing out a personal number.
Listen, whisper and barge, over the top of any call. Whisper in particular is what makes a new agent usable in week one.
Yes, number porting is supported, and call flows are rebuilt rather than imported since most incumbent flows do not export.
A step you drop into a call flow so something answers when the team cannot. You write the greeting and set how many turns it may take before a person is brought in. It answers out of your own knowledge base, using only the customer-facing layer when no staff member is on the line, and hands off to the person you named, a queue, a callback or voicemail. A business-hours rule decides when it is active at all.
The pricing section on this page reads the live catalogue and is the authority. It is per seat per month, plus the minutes you use at the published rate for the destination dialled. Each seat entitles one phone number to be provisioned. Rates for all 531 outbound destinations are published in both euros and dollars, and Voice works without the rest of Calisto Interact.
Each seat entitles one number. A solo operator who wants a local number and a toll-free number buys two seats. A team of ten answering on ten numbers pays for ten seats. Provisioning is a separate step from buying the seat, so a seat can sit unused until you need the number it carries.
Outbound calling to 531 destinations, each carrying its own published rate in euros and dollars, with mobile and landline priced separately wherever the carriers price them separately. Inbound calls to your own numbers are carried by the seat price. The full table is on this page.
Yes, logged against the contact and exportable in standard formats.
