Quick verdict

Should KrispCall be on your shortlist?

Strongest use case
A UK small business of five to fifty people that wants a shared +44 number with multi-level IVR, call recording, live coaching and CRM logging, and that is happy to run telephony through apps rather than desk phones.
Main limitation
Prices are published only in US dollars, bundled minutes exclude UK mobile calls, non-geographic 03 and 033 numbers are marked unavailable, and the public security page has not been refreshed since February 2022.
Who should investigate it
Teams already running HubSpot, Salesforce, Pipedrive, Zoho or Zendesk that want click-to-call and automatic call logging, and buyers who prefer a published seat limit, published number prices and a documented porting process over a bespoke quote.
When another approach makes more sense
Look elsewhere when you need a UK contracting entity, UK or EEA data residency, 0333 non-geographic numbers, sterling billing, granular role permissions, or an enterprise security pack you can hand straight to a procurement team.

Definition

What is KrispCall?

KrispCall is a cloud phone system sold to businesses that want a real telephone number, call handling and a shared workspace without buying a PBX or desk phones. The vendor describes it as an AI-powered communication platform, and the product surface supports that framing: virtual numbers, multi-level IVR, call routing and forwarding, a shared number, call recording, live monitoring with listening, whispering and barging, voicemail, SMS and MMS, a power dialer, call analytics, and an AI layer that produces summaries, transcripts, replies and rephrased messages. KrispCall Communications Inc. was founded in January 2022 by two long-time business partners, trades from Dover, Delaware with a second office in Singapore, and claims 9,000-plus businesses and coverage in more than 160 countries.

The United Kingdom is one of the better-served markets. The pricing page promises one free US, UK or Canada number per user on every plan, and the dedicated UK page prices extra numbers at $4 a month for local and mobile numbers and $5 a month for toll-free numbers. The country coverage page marks UK local geographic numbers as available, UK mobile numbers as available, UK toll-free 0800 and 0808 numbers as available, and UK non-geographic numbers as not available. That single row matters: a business that wants a 0333 number for a national-rate sales line will not find it here, even though KrispCall's own UK explainer walks readers through the 01/02 geographic range, the 03 and 033 non-geographic range, 07 mobiles and the charged 0844, 0845, 0870 and 0871 service numbers.

On the team side the product is built around a shared phone system. A shared number lets several members call and text from the same line, rings everyone at once, stops ringing for the others as soon as one person picks up, and keeps messages, voicemails, call history and internal comments synchronised so nobody double-handles a conversation. Routing is handled by multi-level IVR menus, call forwarding, transfer and call queuing, which the pricing comparison still lists as coming soon along with ring strategies. Seats are capped by plan: five users on Starter, fifty on Advance, and unlimited on Max and Enterprise, with only two published roles, Admin and Member.

Recording and analytics are where the product earns its price. Recording is available from the Advance plan upward, can be started manually from the call menu or turned on per number through an auto-record switch that only exists on the web and desktop app, and is described as unlimited subject to a Fair Usage Policy. Supervisors get call listening, whispering and barging, and the analytics dashboard reports volume, answer rates, missed calls and team activity. The commercial layer is the part UK buyers should read carefully: the subscription buys seats, one free number per user, a bundle of minutes and a bundle of SMS segments, while calls beyond the bundle, texts to non-US destinations and every additional number are charged from a credit balance at published usage rates.

UK Business Stack classifies KrispCall as the telephony layer of a small-business stack. It sits between the channels where customer calls and texts arrive and the system of record where those conversations are supposed to be logged, and it has enough integrations and dialer tooling to hold that middle on its own. What it does not do is change the fact that you are contracting with a US company, paying in dollars, and sending call data to be processed in the United States.

Stack position

How KrispCall fits into a small-business stack

KrispCall occupies the ground a desk phone, an answering service and a call log spreadsheet usually share. A customer dials a UK number, a multi-level IVR or a shared ring decides who picks up, the conversation is recorded and coached where the plan allows it, and the integration writes the outcome back against the customer record so nobody retypes it.

The integration story is the strongest part of the product and also the easiest to over-read. The pricing comparison names well over a hundred connections spanning CRM, helpdesk, automation and collaboration, from Salesforce and Microsoft Dynamics 365 down to niche tools such as Less Annoying CRM and HaloPSA, with Zapier, Make, n8n, Pabbly Connect, Integrately, Activepieces and Pipedream filling the gaps. API and webhook access, however, is still listed as coming soon, so teams that want to build their own sync have to wait or lean on a connector.

The UK question is about commercials and data location rather than capability. KrispCall supports UK numbers, UK mobile porting and UK-specific document checks that reference Companies House, but it has no UK entity, bills only in dollars, routes personal data for processing to the United States, and publishes no UK or EEA data-residency option.

CRM

Salesforce, HubSpot, Pipedrive, Zoho CRM, Copper, Close, OnePageCRM, Attio, Folk, Insightly and Microsoft Dynamics 365 are all listed, so most small-business CRMs can log calls without a middleware layer.

Automation and data

Zapier, Make, n8n, Pabbly Connect, Integrately, Activepieces, Pipedream and Keragon cover the rest of the stack, though the native API and webhook access is still marked as coming soon.

Support and collaboration desks

Zendesk, Intercom, Front, Help Scout, Gorgias, Zoho Desk, Freshservice, Slack and Microsoft Teams receive call history and alerts, which is how support teams keep telephony out of a separate silo.

UK carriers for porting

Published guides cover moving numbers off EE, O2, Three and Vodafone UK; a signed letter of authorization, a recent bill and a verifiable service address are required, and the old account must stay live until the port completes.

Core workflow

How KrispCall works

The flow below reflects KrispCall's published pricing page, country coverage page, porting pages and help-desk articles. UK Business Stack has not run a live KrispCall subscription or placed a test call for this review, so treat these steps as documented behaviour rather than tested behaviour.

Step 1

Create the workspace and pick a billing cycle

Registration asks for a name, email, phone number and password, then a workspace name, a plan and a monthly or annual billing cycle, and finally card details; a valid credit or debit card is required and email verification unlocks the dashboard.

Step 2

Claim the free number or buy a UK number

Every plan includes one free US, UK or Canada number per user. Additional UK local or mobile numbers start at $4 a month and toll-free 0800 and 0808 numbers at $5 a month, with document checks published on the country coverage page.

Step 3

Complete identity verification

KrispCall runs basic KYC to lift initial daily limits and a selfie check for full verification, and its own pricing disclaimer warns that call and SMS functionality is limited until KYC is finished.

Step 4

Build the routing and the shared line

Configure multi-level IVR menus, call forwarding, transfer rules and a shared number that rings everyone concurrently, then add voicemail greetings, on-hold music and business hours through the settings panel.

Step 5

Install the clients and invite the team

Add members by email from Settings, assign each either the Admin or the Member role, group them into teams, and install the web dialer, Chrome extension and mobile apps so the line rings wherever people work.

Step 6

Turn on recording and auto-record

Recording is an Advance, Max or Enterprise feature; the record button sits in the call menu, and auto-record is switched on per number from My Numbers on the web app only, after you have told callers the conversation is being recorded.

Step 7

Connect the CRM and the dialer

Enable the integration for your CRM so calls, contacts and outcomes sync, and set up the power dialer, voicemail drop and custom caller ID for outbound work; Salesforce integration is listed from the Advance plan upward.

Step 8

Watch the bundle and the credit balance

Monitor pooled minutes and SMS segments against the Fair Usage Policy, top up credit for UK mobile calls and non-US texts, and review the analytics dashboard for answer rates, missed calls and agent activity.

Capabilities

Key features that actually matter

1

UK and international virtual numbers

One free US, UK or Canada number per user on every plan, plus UK local 01/02, mobile 07 and toll-free 0800 and 0808 numbers from $4 or $5 a month, within a catalogue the vendor describes as covering more than 160 countries.

Trade-off: UK non-geographic numbers are marked unavailable on the country coverage page, and document requirements for UK numbers include a valid non-virtual phone number and, for some businesses, a commercial register excerpt.

2

Multi-level IVR and call routing

Multi-level IVR phone trees, call routing, forwarding, transfer, custom caller ID and do-not-disturb rules let a small team answer like a much larger one without anyone manning a switchboard.

Trade-off: Call queuing and ring strategies are still listed as coming soon on the pricing comparison, so businesses that need formal queueing or sequential ring orders should confirm the current status before buying.

3

Shared number and team calling

A shared number rings every member at once, stops ringing for the rest once someone answers, allows concurrent calls, and synchronises messages, voicemails, history, typing indicators and internal comments across the team.

Trade-off: Only two workspace roles are published, Admin and Member, so there is no fine-grained permission separating who may listen to recordings from who may see billing or export contact data.

4

Call recording and live monitoring

Manual recording, number-specific auto-record, pause and resume, playback, download, call listening, whispering and barging, plus transcripts and summaries, give supervisors a genuine coaching toolkit on the Advance plan and above.

Trade-off: Recording is absent from Starter, the help desk says all members with access to the number can listen, and deletion is restricted to owners and admins — access control is coarse for a recorded dataset.

5

Power dialer and outbound tooling

The power dialer, voicemail drop, custom caller ID, call notes, call logs and bulk SMS campaigns let a sales team work a list from the same system that answers inbound calls.

Trade-off: The dialer and bulk SMS are not on Starter, and the click-to-call button and widget is listed as coming soon, which limits browser-based calling for the cheapest tier.

6

Unified Callbox and messaging

Unified Callbox puts calls, texts, voicemail, notes and contacts in one place with a lightweight CRM, contact tags, starred messages, SMS forwarding, MMS and internal reply threads on a single workspace.

Trade-off: Bundled SMS segments apply only to US and Canadian numbers, so UK texting runs off the credit balance at standard per-segment rates, and bulk campaigns trigger US A2P 10DLC registration fees.

7

AI Copilot for conversations

Call summaries, transcription, voicemail transcription, AI reply and AI rephrasing turn recorded conversations into searchable text and drafted responses, with an AI Voice Agent and noise cancellation shown as coming soon.

Trade-off: Transcript and summary access is listed as an add-on on the pricing page, so teams should confirm whether AI features are included in their plan or billed on top before committing.

8

Integrations and CRM workflows

More than a hundred named integrations span CRM, helpdesk, automation and collaboration, with Zapier, Make, n8n, Pabbly Connect, Integrately, Activepieces and Pipedream as connective tissue and Google Workspace still marked coming soon.

Trade-off: Native API and webhook access is listed as coming soon, which pushes any bespoke integration through a third-party connector and adds a subscription and a failure point.

Best use cases

When KrispCall earns its place

One published number for the whole team

A UK firm that wants a single 01, 02, 07 or 0800 number on the website and vans, ringing everyone at once and falling through to voicemail when nobody answers.

Remote and hybrid teams

Staff spread across home, office and site who need the business line on a laptop through the web dialer and on a phone through the iOS or Android app, with no desk phone to ship.

Outbound sales with a shared inbound line

Teams that run lists through the power dialer in the morning and take inbound enquiries on the same number in the afternoon, with custom caller ID keeping the outward identity consistent.

Support coaching and quality review

Supervisors who want listening, whispering and barging during live calls and transcripts, summaries and recordings afterwards for training and dispute handling.

CRM-centric operations

Businesses running HubSpot, Salesforce, Pipedrive, Zoho or Zendesk that want click-to-call and automatic activity logging rather than manual notes after every conversation.

International presence without offices

Companies selling into several markets that want local numbers abroad while answering everything from one UK-run dashboard and one monthly bill.

Buyer fit

Who should consider KrispCall?

UK teams of roughly five to fifty people

Starter caps at five users and Advance at fifty, which lines up with the small-business sweet spot where a shared line and an IVR replace a receptionist.

Buyers who want published prices and seat limits

Per-user rates, allowances, seat caps and number prices are all on the public pricing page, which suits teams that prefer to model cost before talking to sales.

Sales and support teams that need coaching tools

Listening, whispering, barging, recording, transcripts and summaries are genuinely useful for managers coaching a small customer-facing team.

Businesses already committed to a named CRM

If your system of record is Salesforce, HubSpot, Pipedrive, Zoho, Freshsales, Copper, Close or Dynamics 365, a listed integration removes a whole category of manual logging.

Organisations comfortable with US processing

Buyers whose data-protection impact assessment accepts transfer and processing in the United States, backed by the vendor's published data processing agreement.

Buyer fit

Who should probably not choose KrispCall?

Firms that must advertise a 0333 number

UK non-geographic numbers are marked unavailable on the country coverage page, so a national-rate line has to come from a different provider.

Procurement that needs a UK entity or UK hosting

The contract is with a Delaware company under Delaware law, personal data is processed in the United States, and no UK or EEA data-residency option is published.

Security teams that want a current evidence pack

The public security page was last updated in February 2022, names no certificate body or certificate number, and does not state where data centres are located.

Buyers who expect a trial before paying

There is no free plan and no free trial; evaluation depends on a 14-day unconditional refund that covers subscription plans only, not numbers, credits or add-ons.

Heavy callers on the cheapest tier

Starter allows five users, 200 outbound and 200 inbound minutes each, 100 SMS segments, and no call recording, power dialer or bulk SMS at all.

Teams that need granular permissions

Only Admin and Member roles are published, so separation of duties over recordings, exports and billing has to be handled by policy rather than by the product.

Alternative approach

KrispCall vs doing it another way

Before subscribing to any cloud phone system it is worth naming the honest alternatives. All of them can put a business number in front of customers; they differ in where the data sits, who you contract with, how the money is denominated and what happens when you leave.

Ordinary alternatives to KrispCall, compared on what each route actually involves.
Alternative routeWhat it involves in practice
A UK-resident VoIP providerBT Cloud Voice and Gamma Horizon sell UK numbers through UK entities with sterling billing and UK support, which suits regulated buyers, at the cost of a smaller international footprint and usually a longer contract.
A global unified communications suiteRingCentral, 8x8, Vonage and Dialpad bundle calling with messaging and video, publish named security certifications and hold larger integration ecosystems, and generally cost more per seat than KrispCall's published rates.
A sales-focused call deskAircall and Calilio are built around team calling, dialing and call analytics with simpler pricing, which suits a pure sales motion but often has less IVR and monitoring depth than KrispCall publishes.
A second number on a mobileGrasshopper gives a sole trader or very small firm a separate business number cheaply and quickly, without IVR, recording, monitoring or CRM sync — enough for some businesses and clearly not enough for others.
Staying on the current systemDeferring is a legitimate option while the existing line works; porting mid-contract creates documentation, timing and downtime-management work, and should solve a problem you actually have.

Rollout

Implementation and adoption

  1. Verify your UK number type before subscribing

    Confirm the exact 01, 02, 07 or 0800 number you want is purchasable and that the document pack you can supply satisfies the country coverage requirements for individuals or businesses.

  2. Model the true monthly cost in dollars

    Take the per-user price, add extra numbers at $4 or $5 each, then add UK mobile minutes and non-US text segments at usage rates, and convert to sterling at a rate you have budgeted rather than today's.

  3. Check what your plan actually unlocks

    Recording, transcripts, bulk SMS and the power dialer start at Advance, while call queuing, ring strategy, desktop apps, API access and Google Workspace are marked coming soon across the comparison.

  4. Announce recording and set a retention rule

    Tell callers the call is recorded and offer an opt-out as the help desk advises, then agree a retention period that meets your UK GDPR obligations rather than simply inheriting the vendor's one-year default.

  5. Run the port in parallel, not in sequence

    Keep the old account paid up, forward incoming calls to the temporary number KrispCall provides, and expect two to four weeks end to end with the letter of authorization details matching your carrier record exactly.

  6. Test call quality on the networks you use

    Voice runs over the internet rather than a copper line, so trial the web dialer, extension and mobile apps on office Wi-Fi, home broadband and mobile data before rolling out to the whole team.

  7. Read the refund and credit rules

    The 14-day unconditional refund applies to subscription plans only, account credit can be spent on calls and texts but not on numbers or renewals, and annual plans are prepaid.

UK context

UK small-business considerations

  • Who you are contracting with. KrispCall Communications Inc. of 8 The Green STE A, Dover, Delaware 19901, with an office at 20 Cecil Street in Singapore; the terms are governed by Delaware law and there is no UK-registered entity or UK address.
  • The shape of the UK numbering plan. 01 and 02 are geographic codes tied to an area, 03 and 033 are non-geographic numbers charged at normal landline rates, 07 is mobile, and 0800 and 0808 are freephone; KrispCall offers all but the non-geographic range.
  • Whether calls run over the PSTN or over IP. KrispCall explains that calls to a virtual number are routed over the internet by VoIP to your devices rather than terminating on a traditional UK landline, and it does not publish which UK carrier it hands off to or any UK licence it holds.
  • Ofcom and number provisioning claims. The vendor's UK page says it provides properly provisioned numbers so you stay 'fully Ofcom-compliant', but no page names an Ofcom registration, a UK carrier partner or a communications licence held by KrispCall itself.
  • Currency and tax. There is no sterling price list and no published UK VAT treatment, so the £ cost of the subscription moves with the exchange rate; confirm with KrispCall and your accountant how VAT is applied to a purchase from a US supplier.
  • Where the data sits. The privacy policy, last updated 21 July 2026, states that personal data is transferred to and maintained in the United States and processed there; no UK or EEA data-residency option is published for a UK buyer.
  • Recording, interception and your own obligations. The terms say KrispCall takes no responsibility for obtaining consent or issuing notices for recording and that the customer is solely responsible; nothing on the site addresses the Investigatory Powers Act 2016 or lawful-interception requests.
  • Text messaging rules for UK recipients. Bundled SMS is US and Canada only, opt-out keywords follow US A2P conventions, and marketing texts to UK individuals engage PECR consent rules that KrispCall's documentation does not discuss.

Buying guidance

Pricing and value considerations

KrispCall publishes four tiers, all priced per user per month in US dollars: Starter at $15, Advance at $40 and Max at $60 on monthly billing, falling to $12, $32 and $48 when billed annually, which is a 20 per cent discount; Enterprise is a custom quote for fifty-plus seats. Seat caps are five, fifty, unlimited and unlimited respectively, and no setup or onboarding fee is charged.

The subscription does not buy unlimited communication. Each plan bundles one free US, UK or Canada number per user, a monthly allocation of outbound and inbound minutes, and a pool of SMS segments; calls and texts beyond those allowances, every additional number, and all non-US messaging are billed from a credit balance at published usage rates that KrispCall presents through an interactive calculator rather than a static table.

Two structural points deserve attention from a UK buyer. The Fair Usage Policy states that bundled minutes apply to calls to local numbers in the US, Canada, the UK and Australia, and that standard charges still apply to UK mobile calls even on the unlimited Max plan. And because there is no sterling price list, the £ cost of the same subscription drifts with the exchange rate between the day you model it and the day you are charged.

1

What drives value

  • One free US, UK or Canada number per user on every plan, which removes the number rental from the entry price
  • A published 20 per cent annual discount that takes the entry tier to $12 per user per month
  • UK local, mobile and toll-free numbers priced openly at $4 or $5 a month rather than hidden behind a quote
  • Bundled minutes and SMS segments pooled at account level, which rewards a team rather than penalising uneven usage
  • No setup or onboarding fees, and a 14-day unconditional refund on subscription plans for a change of mind
  • Non-profit organisations can request a discount with proof of status, and early-stage firms can apply for six months free
2

What drives cost

  • US dollar billing with no sterling price list, so exchange movement and card charges sit on top of the headline price
  • UK mobile calls charged at standard rates even on the unlimited Max plan, because bundled minutes cover local numbers only
  • Non-US text segments billed per segment from credit, with the bundled allowance limited to US and Canadian numbers
  • One-off US messaging fees that appear in the comparison: a $4.50 brand registration, a $15 campaign vetting fee and monthly campaign charges
  • Transcripts and summaries flagged as an add-on, plus extra numbers, non-VoIP numbers and international calling priced separately
  • Starter caps at five users with no call recording, no power dialer and no bulk SMS, which pushes most real teams up a tier
3

Check before you buy

  • Your expected total in dollars, including seats, extra numbers, UK mobile minutes and non-US text segments at realistic volumes
  • Which plan carries each feature you need, since recording, transcripts, bulk SMS and the dialer are gated by tier
  • Whether the UK number type you intend to advertise is available, confirming 01, 02, 07 or 0800 rather than assuming 0333
  • How VAT will be applied to a subscription bought from a US supplier, and whether your finance team is content with dollar invoicing
  • What happens to recordings and logs if you stop paying, given the published one-year retention and fifteen-day deletion after expiry
  • The current status of features marked coming soon, including call queuing, ring strategy, desktop apps and API and webhook access

Trade-offs

Important limitations of KrispCall

  • No UK entity and no UK data residency. The contract is with a Delaware company governed by Delaware law, the Singapore office is the only other published location, and personal data is transferred to and processed in the United States.
  • A stale public security page. The security and compliance page carries a last-updated date of 21 February 2022 and describes HTTPS, role permissions and backups without naming a certificate, a certifying body or a data-centre region.
  • Certification claims are hard to verify. The pricing page markets an ISO 27001 certification and Enterprise lists ISO 27001 compliance support, yet no certificate number, registry entry or audit report is published, and SOC 2 is not mentioned anywhere.
  • UK non-geographic numbers are unavailable. The country coverage page marks UK national numbers as unavailable, so 03 and 033 ranges cannot be bought, which excludes a common choice for UK sales and support lines.
  • Bundled minutes quietly exclude UK mobiles. The Fair Usage Policy applies included minutes to local numbers in the US, Canada, the UK and Australia and states that standard charges apply to UK mobile calls, a detail easy to miss on the pricing page.
  • Recording and outbound tooling need a paid tier. Call recording, transcripts, bulk SMS and the power dialer are absent from Starter, so a business on the $15 tier buys a dial tone with an IVR rather than a full quality-assurance platform.
  • Only two roles and coarse recording access. Admin and Member are the published roles, and the help desk notes that everyone with access to a number can listen to its recordings, which is thin control over sensitive audio.
  • Several roadmap items still marked coming soon. Call queuing, ring strategies, desktop apps for Windows, macOS and Linux, the click-to-call widget, API and webhook access and Google Workspace integration all carry coming-soon labels.

Decision framework

Deciding on KrispCall

Consider KrispCall if

  • You want one published UK number with IVR, voicemail and a shared ring instead of a mobile number on every business card
  • Your team of up to fifty needs recording, live coaching and CRM logging from the same system that answers the phone
  • You run Salesforce, HubSpot, Pipedrive, Zoho or Zendesk and want click-to-call and automatic activity capture
  • You are content to budget in US dollars and to model UK mobile minutes and texts as usage charges on top
  • You accept that call data will be transferred to and processed in the United States under the vendor's DPA
  • You need UK local, mobile or toll-free numbers rather than a 0333 line, and can supply the published document pack

Look elsewhere if

  • You need a UK contracting entity, English governing law or a UK or EEA data-residency commitment
  • A 0333 or other non-geographic UK number is central to your brand or call-cost strategy
  • Your procurement process requires a current ISO 27001 or SOC 2 certificate you can inspect before signature
  • You want to trial the system on a free plan or a genuine trial period before committing money
  • You need granular roles, formal call queuing, ring strategies or an API on day one
  • A UK-based alternative such as BT Cloud Voice or Gamma Horizon would satisfy your compliance and support requirements more easily

Pros

  • One free US, UK or Canada number per user on every plan, with UK local, mobile and toll-free types published openly at $4 or $5 a month for additional numbers
  • A deep call desk: multi-level IVR, routing, forwarding, transfer, a shared number, live listening, whispering and barging, plus a power dialer for outbound teams
  • A wide integration catalogue including Salesforce, HubSpot, Pipedrive, Zoho CRM, Zendesk, Intercom, monday.com and Microsoft Dynamics 365 rather than a handful of headline names
  • Seat limits and per-user prices published on the pricing page, with a 20 per cent annual discount and no setup or onboarding fees
  • Number porting documented end to end, including guides for EE, O2, Three and Vodafone UK and a temporary number so calls keep working during the move
  • Support advertised around the clock by live chat and email, with a public system status page and a 14-day unconditional refund on subscription plans

Cons

  • Every price is in US dollars with no sterling price list, so the real cost moves with the exchange rate and card charges
  • Bundled minutes cover calls to UK local numbers only, and UK mobile calls are charged at standard rates even on the supposedly unlimited Max plan
  • Call recording, transcripts, bulk SMS and the power dialer all sit on the Advance plan or above, leaving Starter buyers with a thin product
  • UK non-geographic 03 and 033 numbers are marked unavailable on the country coverage page, ruling out the 0333 numbers many UK firms advertise
  • The security and compliance page was last updated in February 2022 and names no certificate number, certifying body or data-centre location
  • Only two workspace roles, Admin and Member, are published, which is coarse for teams that need scoped permissions over recordings and billing

Final verdict

Where KrispCall makes sense

KrispCall makes a credible case to a specific UK buyer: a small business that wants one professional number, real call handling and CRM logging without buying a phone system. The capability list is broad and mostly available today — multi-level IVR, routing, forwarding, a shared number, recording with pause and resume, listening, whispering and barging, a power dialer, a unified inbox, SMS and MMS, and more than a hundred named integrations. The UK details hold up under checking: a free number per user on every plan, published prices for UK local, mobile and toll-free numbers, document requirements that name Companies House, and porting guides for the four big UK mobile networks. That is more UK specificity than many US-centric products bother to publish.

The commercial and compliance edges are where a UK buyer should slow down. Everything is denominated in dollars, the Fair Usage Policy quietly carves UK mobile calls out of the bundled minutes, call recording and the dialer start at the $40 tier, and non-geographic 0333 numbers simply do not exist in the catalogue. On assurance, the picture is mixed: the privacy policy is current and names a DPA, GDPR, PCI DSS and ISO 27001:2022 compliance, while the security page has not been touched since February 2022 and no certificate or data-centre location is published. Recording is a capability, not a compliance service — the terms put consent and notice entirely on the customer.

Before committing, verify four things directly with KrispCall. First, your total monthly cost in dollars at real volumes, including UK mobile minutes, texts and extra numbers. Second, that your intended UK number type is purchasable and that you can satisfy its document requirements. Third, ask for the current ISO 27001 certificate, any SOC 2 report, the data-centre regions used and the DPA, because the public pages will not answer those questions. Fourth, confirm which of the coming-soon features matter to you and when they ship. If those answers are satisfactory, KrispCall is a well-priced, feature-rich way for a UK small business to run professional calling — and worth comparing against Calilio on price and RingCentral or Aircall on maturity before you sign.

FAQ

Common questions

Does KrispCall offer UK phone numbers?

Yes. KrispCall offers UK local 01/02, mobile 07 and toll-free 0800 and 0808 numbers, and gives every user one free US, UK or Canada number on any paid plan; additional UK local and mobile numbers cost $4 a month and toll-free numbers $5 a month. UK non-geographic 03 and 033 numbers are marked as unavailable on the country coverage page.

How much does KrispCall cost?

Prices are published in US dollars per user per month: Starter $15 or $12 billed annually, Advance $40 or $32, Max $60 or $48, with a 20 per cent discount for annual billing and Enterprise quoted for fifty or more seats. Calls, texts and additional numbers are charged separately from a credit balance. Confirm current pricing with KrispCall.

Is there a free trial or a free plan?

No. KrispCall states it does not offer a free trial or a free plan. Evaluation relies on a 14-day unconditional refund that applies to subscription plans only — add-ons, virtual numbers, credits and other one-time purchases are not refundable.

Can I move my existing UK number across?

Yes, porting is available on every plan. You email porting@krispcall.com with your numbers in international format, a signed letter of authorization, your current provider's name and a recent bill; KrispCall confirms eligibility within one business day and the port typically completes in two to four weeks, with a temporary number keeping calls live. Keep your old service running until the port finishes.

Is call recording lawful in the UK?

KrispCall supplies the recording capability; the lawfulness is yours. The terms state that KrispCall takes no responsibility for obtaining consent or issuing notices and that the customer is solely responsible for compliance. In practice you need a UK GDPR lawful basis, to tell callers the call is being recorded, to set and honour a retention period, and to keep records of that decision.

Where is my data stored?

The privacy policy, last updated 21 July 2026, states that personal data may be transferred to and maintained in the United States and processed there. No UK or EEA data-residency option is published, and a data processing agreement is referenced. Recordings, logs and transcripts are retained for one year for active users, with workspace data deleted fifteen days after expiry.

Is KrispCall ISO 27001 certified?

The pricing page markets an ISO 27001 certification and Enterprise includes ISO 27001 compliance support, while the privacy policy refers to ISO 27001:2022 compliance. No certificate number, certifying body or audit report is published, the security page was last updated in February 2022, and SOC 2 is not mentioned — ask for the evidence pack before procurement signs off.

Which CRMs and tools does KrispCall connect to?

The vendor lists more than a hundred integrations, including Salesforce, HubSpot, Pipedrive, Zoho CRM, Zendesk, Intercom, monday.com, Microsoft Dynamics 365, Slack, Microsoft Teams, Notion, Klaviyo, ActiveCampaign and Zapier, with Make, n8n, Pabbly Connect and Pipedream for custom flows. Google Workspace and native API and webhook access are both listed as coming soon.
