Questions, answered

An AI phone-call platform. You draw a call as a workflow — what to say, what to ask, what to do with the answers — and HelloCall answers and places calls on your numbers with it: listening, understanding, speaking in a natural voice, looking things up in your systems, and writing everything down.

Any business that takes or makes a lot of routine calls: clinics, salons, restaurants, shops, real-estate and service businesses, support desks, collections and sales teams. No technical skills are needed to build a workflow — describe it in words and HelloCall drafts it.

Greet callers, answer questions from your FAQ, collect details, understand keypad presses, check your systems through an API, book callbacks, hand over to a person, send a WhatsApp or an email to your team, summarise the call, and save the caller to your contacts.

Pay as you go is ₹2 per started minute with no fee. Yearly plans charge per second: Pro is ₹6,000 a year at ₹1.20 a minute, Pro Max ₹15,000 a year at ₹0.60 a minute. AI tokens are ₹250 per million in and ₹500 per million out. See Plans, wallet and billing.

Yes. Every new organisation gets ₹100 of credit at the Pro rate, with no card needed, and browser test calls are free.

Calls that do not connect, browser test calls, team members, workflows and numbers you add. Talk time on your own SIM in a local modem is not charged either — only the AI tokens.

251 languages and locales. 144 have natural synthesised voices — including Hindi, Bangla, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu and Indian English — and the rest work with your own recordings. Each workflow has one language; Translate & duplicate makes a copy in another.

Numbers on your own Plivo account (bought in the console or imported), and SIM cards in USB modems on a computer running the HelloCall desktop app. Both work the same way once imported.

Yes, in two ways: import it if it is on your Plivo account, or put its SIM in a local modem — the calls then go out and come in on that very number, on your existing mobile plan.

Both, with the same workflows. A number’s incoming workflow answers it; the Call button, scheduled calls and campaigns call out.

Yes. The Transfer to human step rings one number or a list, and if nobody answers the call carries on so the agent can take a message. Transfers work on Plivo numbers.

Yes. The Call an API step calls your system during or after the call, and uses the reply. DataMold forms and WhatsApp through Wago connect without any code.

That is up to you — you write every word the agent says, starting with the greeting. Many businesses say so up front (“This is the virtual assistant of …”), which callers tend to appreciate.

With a Google account. There is no separate HelloCall password. Colleagues join when an admin adds their Google email under Settings → Users.

Sign-in is through Google. Credentials you give HelloCall — your Plivo token, secrets, integration keys — are encrypted and never shown again; API keys are stored only as a fingerprint. Each organisation’s data is kept in its own separate store, and calls and transcripts are deleted after 30 days.

30 days for call records, transcripts and collected values, then they are deleted automatically. Recordings stay on your own Plivo account. Send anything you want to keep to your own systems with a step below End call.

Only when recording is switched on for the number (Call tuning, or for every number under Settings → Organisation → Calling defaults). Recordings are kept on your Plivo account. Transcripts are kept for every call for 30 days.

Yes. The console works in a phone’s browser — every page fits a small screen. Designing large workflows is easier on a computer.

No, a browser is enough. The desktop app (Windows, macOS, Linux) is only needed on a computer with local SIM modems.

On a Plivo number several calls can run together; a campaign dials up to 10 at a time from one line. A SIM in a local modem carries one call at a time, so add SIMs for more.

New calls are not connected, and callers hear your “wallet is empty” message. A call in progress that uses up the balance ends with the same message. The balance never goes negative. Add credit under Settings → Wallet & billing.

Yes. Every payment has a PDF receipt under Settings → Wallet & billing → Payments, with your billing address and GSTIN from Settings → Organisation.

Yes. Plivo numbers are available in India, the US, the UK, Australia, Canada, Singapore and the UAE, workflows speak 251 languages, and your working hours follow your own timezone. Payments are in rupees through Razorpay.

A workflow follows the steps you drew, every time — it is how HelloCall calls are built. An agent is an older, free-talking AI set up with one system message; it still works for a number with no workflow, but new work should use workflows.

Yes. Record or upload your own audio for any spoken step, and with an Inworld account connected, even the values (names, dates, amounts) can be read in your own cloned voice.

Raise a ticket under Settings → Support tickets in the console — the team replies there and may call you. The support email address is at the bottom of every page of this site.

No. Every new organisation starts with ₹100 of credit at the Pro rate. Choose a plan when you want to add more.

No. You can build a workflow and talk to it with a free browser test call before you have any number.

With a Plivo account ready, about fifteen minutes: import a number, describe a workflow, test it, and set it as the number’s incoming workflow.

Yes. Add colleagues by their Google email under Settings → Users; there is no charge per member.

The console works in any modern browser, on a computer or a phone. The desktop app for Windows, macOS and Linux is for running local SIM modems.

A HelloCall number is paid from the wallet: the first month when you buy it, then every month after. A number on your own Plivo account is not — Plivo charges its setup fee, monthly rent and carrier charges there. Either way the wallet pays HelloCall’s own usage: the connected seconds of a call and the AI tokens it uses.

A number bought from Crawlink takes incoming calls only until Crawlink switches outgoing calls on for it. Ask Crawlink support; once it is on, the number shows in the Call dialog and campaigns can use it.

It has no incoming workflow, so it cannot answer calls. Press Not routed · Set up now to pick a workflow or create one, or set it in the Routing dialog.

Yes. Choose the same workflow in each number’s routing. A workflow can also be used for incoming and outgoing calls at once if its Used for setting is Both directions.

Detach from HelloCall only stops it answering here; the number is still rented on your Plivo account. Use Release at Plivo (or release it in the Plivo console) to stop the rent.

A local number places calls through the desktop app on the computer its modem is plugged into. Open the console in that app, or in a browser on that same computer while the app is running. Elsewhere the line is listed but disabled, with the reason.

HelloCall numbers: the countries listed in the buy dialog, which HelloCall chooses. On your own Plivo account: India, the United States, the United Kingdom, Australia, Canada, Singapore and the United Arab Emirates, in the types Plivo stocks there (Local, Toll free, Mobile, National). Some require compliance documents before the number can take calls.

Open Call tuning and raise Pause before answering (ms) — for example from 700 to 1000. It is how long the caller must be silent before the agent replies.

Only when Record calls is on in the number’s Call tuning. Recordings are made and kept on your Plivo account; HelloCall plays and downloads them from the call’s details without storing a copy. Transcripts are kept for every call either way.

No. Remove line returns the SIM to Settings → Local modem as not enabled and keeps its call history. Enable it again from its modem card and set its routing.

SIMCom SIM7600-series USB 4G modems, which carry call audio over USB. The HelloCall USB modem in the console’s device store is one. Other dongles may dial but cannot carry the conversation — Run checks tells you.

No. A local-modem call is not charged talk time by HelloCall; your mobile plan pays the carrier. The AI tokens a call uses (for example a HelloCall Agent or a summary) are still charged at your plan’s token rates.

New SIMs are only detected. Enable it from its card under Settings → Local modem. If the modem is not there either, check the desktop app is running and signed in on that computer.

Many SIMs do not store their own number. Use Set SIM number, or type the number when you import the SIM. To find it, make a Test call to your own mobile and read the caller id.

The desktop app is not running, the computer is off or asleep, the modem is unplugged, or the modem is switched off in its settings. Hover over Offline on the Phone numbers page for the exact reason.

Check three things: the app is signed in on the modem’s computer, Answer incoming calls automatically is on in the modem’s settings, and the number has an Incoming workflow in its routing. Missed calls are filed in Call history with the reason.

One at a time, and up to 200 outgoing calls and 200 SMS a day. For more, add more SIMs — several modems on one computer work together.

Not yet: a SIM call cannot be bridged to a second number. Use a Plivo number for workflows with a Transfer to human step.

Something on the modems’ computer has to dial. The desktop app does this even with its window closed, because it keeps running in the tray. In a plain browser tab, keep the tab open while the campaign runs.

Run Run checks and look at USB call audio. If it fails, the modem cannot carry call audio over USB. Try the Echo test after re-plugging the modem, and Reset modem if it persists.

Only on a computer with local modems (SIM cards in USB modems). With Plivo numbers, a browser or phone is all you need.

Yes — it keeps running in the system tray (the menu bar on a Mac), answering calls and dialling campaigns. Use Quit HelloCall in the tray menu to stop it.

Google does not allow sign-in inside an app window. The app opens your browser, you sign in there, and the browser hands the app a one-time code. Your password never passes through the app.

Yes, if Start when I sign in to this computer is on (it is by default). The app starts in the tray, already signed in, and the modems come back on their own. Make sure the computer does not sleep.

Windows and Linux (64-bit) and macOS. The download buttons are on Settings → Local modem while the app is not running on the computer you are using.

Yes. Each computer runs its own app with its own modems; every SIM is imported once and then shows its online status wherever you look. Campaigns on a local number are dialled from the computer that has that SIM.

Yes. The app only accepts connections from the same computer, uses a new key every time it starts, and keeps your sign-in in its own local storage. It carries the call audio to HelloCall over an encrypted connection.

Download the latest installer from Settings → Local modem and install it over the old one. Settings and sign-in are kept.

In the Buy a HelloCall modem dialog, type the code under Coupon code and press Apply. The price box shows the coupon’s saving; it comes off after the offer and before GST. A coupon can have a use limit and an end date — the dialog tells you if a code has expired, has been used up or is not for this purchase.

₹11,500 list price, less the current offer (5% to 12% off), plus 18% GST on the offer price — between ₹11,941.60 and ₹12,891.50 in total. The exact figure is shown before you pay.

On the discounted price. The discount comes off first, then 18% GST is added.

Yes — up to 10 in one order, all at the same offer. For more, place a second order or write to support about a bulk price.

From time to time — it is always between 5% and 12% off, the same for everybody. The buy dialog shows the current offer and until when it is valid.

No. Use your own SIM with a voice plan — its calls go out on that plan. Turn off the SIM’s PIN lock before inserting it.

Through Razorpay, by UPI, card or net banking, from Buy a modem on Settings → Local modem or Settings → Plan. You get an order number when the payment succeeds.

Once the HelloCall team ships it and assigns it to your organisation. Until then, your order number is the reference for any question — raise a ticket under Settings → Support tickets.

Yes, if it is a SIM7600-series modem with call audio over USB. It works as a local modem the same way; it just will not appear under Settings → Devices & orders, which lists modems bought from HelloCall.

Run Run checks on its card under Settings → Local modem, then press Raise a ticket on the device under Settings → Devices & orders and describe what you see.

No. Give a new workflow a description and the first draft is built when you open it; after that, describe changes in the prompt box or by voice. Drawing by hand is for fine-tuning.

Changes go live when you press Save. Until then the canvas is a draft — look for the dot beside the workflow’s name.

Lines are recorded when you save. After changing the language or voice, select nothing on the canvas and press Regenerate all audio in Workflow settings.

A {variable} is spoken live and joined to the recorded words around it. Put it at the end — “Your total, in rupees, is {amount}” — so there is only one join, at a natural pause.

A workflow has one language. Make a copy per language with Translate & duplicate, and route each number (or campaign) to the right one — or use an Ask Question step to choose, then a Workflow step to run the chosen language’s flow.

Browser test calls do not draw on your wallet, and end after five minutes. AI work in the designer itself — drafting, polishing, translating — uses tokens at your plan’s AI rates.

Yes, but the last Save wins. Agree who is editing, and use Lock on a workflow that is live so nobody changes it by accident.

There is no version history to roll back to. Before a big change, Duplicate the workflow and edit the copy; switch the number’s routing to it when it is ready.

Yes, on any spoken step: Record or upload a voice instead. Record in the browser or upload a file, trim it, and save. The text remains the transcript and the fallback.

They run after the caller hangs up — summaries, emails, API calls, saving to a party. Steps that need a caller (Speak, Ask Question, Transfer) cannot run there and are skipped.

Condition tests values (equal, greater than, contains, empty …) and has two lines, true and false. Match has one line per value of a single variable, plus “no match”. Use Match under an Ask Question step; use Condition for numbers, flags and anything else.

List the possible answers — for example yes and no. AI maps what the caller said onto one of them in any language: “sure, go ahead”, “haan ji” and “okay” all land on yes. Add a note for the AI for readings only you would know.

Steps that need no caller: Call an API, Set variable, Get party info, HelloCall Agent, Summarize call, Extract variables, Save to party, Datamold, Send Wago Message, Notify on WhatsApp and Notify on email. Speak, Ask Question, FAQ and Transfer cannot.

Integration steps appear only when the integration is switched on and connected under Settings → Integrations — that includes the ChatGPT, Inworld and Gemini agent steps, which need their provider connected with a key. Notify on email appears when the platform mailbox is set up.

Store it in Settings → Secret store and write {{name}} where it goes, for example in an Authorization header. The value is added only as the request is sent and never appears in the workflow, the transcript or the logs.

Yes. Use Call an API to fetch it into a variable, then a Speak step with the variable at the end of the line: “The price is {price}”.

Party details are only filled in by a Get party info step. Add one above the first step that uses {party.…}.

By default the call carries on at the step below the Transfer, so you can offer to take a message or try another number. Branch on {human_transfer_state} to tell no_answer from busy or rejected.

Call history shows one phone number at a time — choose the number at the top. Calls older than 30 days are deleted, and browser test calls are not listed under a number.

30 days. Send anything you need to keep longer to your own systems with a step below End call — Call an API, Notify on email or Save to party.

There is no export on Call history. A campaign’s Report downloads its contacts and call log as an Excel file; for everything else, have your workflow send each call to your own system as it ends.

Calls on a local modem are not charged talk time, browser test calls are free, and a call that never connected costs nothing. AI tokens, when used, are shown separately in AI tokens.

In the call’s details under Recording, when the number had Record calls on at the time. Turn it on per number in Call tuning, or for every number under Settings → Organisation → Calling defaults.

The wallet could not fund the call, so it was refused and the caller heard your “wallet is empty” message. Add credit under Settings → Wallet & billing.

The caller’s number is always shown. Add them under Parties (or use a Save to party step) and their name appears on every later call.

Yes — the round phone button on a row in Recent calls on Home opens the Call dialog with the same line, workflow and number.

It needs at least one contact on the list, an active phone number and an active workflow for outgoing calls. It will also only dial inside its calling hours — outside them it waits as Outside calling hours.

Set Calling starts and Calling ends to any half hour from 00:00 to 23:30 in the campaign’s settings — 09:00–19:00 is only the default. Call now on a single contact can ring someone outside the window after you confirm.

Campaigns call every day inside their hours. Pause it on Friday evening and Resume it on Monday.

Every column besides the phone and name becomes a variable, named in lower case with underscores — a column “Order ID” becomes {order_id}. Use it in a Speak step, a Condition or an API call.

Every row from that upload carries the same group id chip. Choose Remove group #id on any of them to remove the whole batch; anyone being called at that moment stays.

Not while they are waiting: a number already on the list is skipped. After their call has finished, they can be added again deliberately for another round.

No. Pause stops new calls; calls already connected finish normally.

The same as any call: talk time at your plan’s rate plus AI tokens, from your wallet, only for calls that connect. On a local modem there is no talk-time charge. The campaign page shows the money spent so far.

A call is only placed when the balance can fund at least a minute. Each contact the campaign reaches while it cannot is recorded as a failed attempt (“Wallet balance is too low to place the call”) and is retried only if it has tries left. Top up before a big campaign; if it runs dry, Pause, add credit and Resume — and add any finished-but-unreached numbers again.

Scheduled calls are placed on the five-minute mark, so a call is made within five minutes of its time.

Not yet — scheduled calls are placed from Plivo numbers. Use a campaign on the local line (with Schedule on its contacts) to ring someone at a time from a SIM.

A scheduled call is tried once and then shows Not picked or Busy. For automatic retries, add the person to a campaign instead.

Your organisation’s timezone, set under Settings → Working hours. The dialog shows it beside the time.

No. A second booking for the same number and workflow within 15 minutes of an existing one is recognised as a duplicate.

Yes, while it is still Scheduled: Reschedule changes the time and details, Cancel stops it being made.

Not into Parties directly. You can upload a spreadsheet into a campaign, and a Save to party step in its workflow can create the parties as the calls happen.

Party details are only available after a Get party info step, and only for parties that have a value in that field. Check {party_found} before relying on it.

No — one number belongs to one party, because the number is how a call finds its party.

Create a campaign, then choose Import from party list and name the tag (or Pick contacts and filter by it).

No. Its calls stay in call history (for their 30 days), shown by number instead of name.

No. Save to party only fills in what it heard and never blanks an existing value, and fields you map by hand in the step always win.

An admin adds their Google account email under Settings → Users → Add member. No email is sent: tell them to sign in with that Google account and they join straight away.

No. HelloCall signs in with Google only, so there is no separate password to manage or leak.

Manage billing and people, edit the organisation’s details, connect integrations, and manage API keys and secrets. Everything else — numbers, workflows, campaigns, calls, parties — is open to them.

Yes. Create an organisation per business under Settings → Organisation → New organisation and switch between them in Profile. Each has its own numbers, workflows, wallet and plan.

The Working hours page sets one opening and one closing time per day. Workflows use them to tell callers when you are open.

Add your team’s WhatsApp numbers under Settings → Organisation → Edit → WhatsApp numbers. The step only ever messages numbers on that list.

In Settings → Organisation → Edit → Billing, with your billing address. Both are printed on every receipt you download.

Make someone else an admin first under Settings → Users; an organisation must always have at least one admin.

Only admins can. A standard user sees “Only an admin can turn this on.”

No. Notify on WhatsApp uses HelloCall’s own number and needs nothing connected — only your team’s numbers on the organisation profile. Wago is for messaging your customers from your own number.

WhatsApp allows free text only to someone who has messaged your number in the last 24 hours. Outside that window the message is queued and sent when they write to you. Use an approved template to reach someone at any time.

Inworld bills your own Inworld account for the speech it generates. HelloCall charges nothing extra for it.

Datamold steps can no longer reach your forms, and the step disappears from the palette. Reconnect to the same DataMold organisation and they work again.

No. You sign in on the other app’s own page; the apps exchange a key between themselves, and it never passes through your browser. Disconnecting revokes it.

Yes — list every website under Websites (up to ten) and paste the same line into each. With Only work on these websites on, conversations can only start from those addresses; the preview in HelloCall still works.

Into Call history like any call, marked “Website”, with the transcript and the visitor’s details. A summary is written to the party when a phone number was given.

Yes. The panel asks the visitor for microphone permission when they choose to call; it runs on HelloCall’s own page inside your site, so nothing on your site needs changing.

No — only a fingerprint is stored. Revoke the lost key and create a new one.

In a header: Authorization: Bearer hck_… or X-API-Key: hck_….

Calls placed through the API go out from Plivo numbers. Local numbers dial through the desktop app on their own computer.

Nobody, once it is saved — not admins, not the workflow, not the logs. It is only added to the request as it leaves.

Yes. Only admins can create, edit or delete them, but anyone building a workflow can reference one by name.

Yes — choose Read only — GET requests when creating it. Access cannot be changed afterwards.

Pay as you go (₹2 a started minute, no fee) suits light or irregular use. Pro (₹6,000 a year, ₹1.20 a minute billed per second) is cheaper for steady use. Pro Max (₹15,000 a year, ₹0.60 a minute) pays for itself past about 25 hours of calling a month.

On Pro or Pro Max, exactly 20 seconds of talk time. On pay as you go, one started minute (₹2). Plus any AI tokens the call used.

Tokens are how AI models measure text. HelloCall charges ₹250 per million tokens sent to a model and ₹500 per million written back, on every plan. A workflow of fixed lines and keypad presses uses very few.

No. The trial is the ₹100 welcome credit; to add credit, choose a plan — pay as you go has no fee.

Calls continue at the Pro rate from your remaining balance, but you cannot add credit until you renew or switch to pay as you go.

₹100, and at most ₹1,00,000 in one payment.

No. The yearly fee pays for the plan and its rate; the wallet is recharged separately and pays for talk time and AI tokens.

No. A call needs at least a minute of balance to connect, and a call that uses up the balance is ended with your “wallet is empty” message.

Settings → Wallet & billing → Payments — Download receipt on any paid row. Add your billing address and GSTIN under Settings → Organisation first so they are printed on it.

No. Plivo bills your Plivo account for the number and carrier charges; a SIM runs on its own mobile plan. HelloCall charges only talk time (not on local modems) and AI tokens.

Some problems are solved fastest by talking. The team may call you on it to understand the issue or to walk you through a fix.

Reply in the ticket’s comment thread. The team sees your reply alongside the rest of the conversation.

When it happened, the numbers involved, the workflow, and what you expected. The call’s Call events and hangup cause from Call history help most.

Yes, on every plan. Pro Max adds priority support on WhatsApp.

Tickets are raised from the console so the team knows your organisation. If you cannot sign in, write to the support address at the bottom of this page.
