Kalyvox is a Toulouse-based AI phone receptionist for small and mid-sized businesses that still live on inbound calls. The SaaS answers in the company name, detects why someone is calling, asks the qualification questions you configured, then applies your rules: transfer to a human, book a calendar slot, answer from your business facts, or create a structured callback ticket.

It exists for teams that miss calls while on site, in meetings, or after hours, and do not want a full-time front desk. You keep your existing business number and choose when to forward: always, unanswered only, or outside opening hours.

The concrete differentiator is rule-driven call outcomes tied to industry-style intents (trades, medical, legal, automotive, and more), plus post-call tickets that bundle summary, transcript, priority, and next action for the team dashboard and notifications.

Shortlist Kalyvox when you need a French-operated AI receptionist for inbound SMB calls with keep-your-number forwarding, intent rules, live transfer, and calendar booking. Skip when you need omnichannel helpdesk workflows, self-hosted or on-device speech, or an EU-only subprocessor graph without US telephony/AI providers. Consider Intercom for multi-channel support, or LiteScribe when transcription locality matters more than live phone coverage.

Key capabilities

Kalyvox provides a number you can forward to, or answers on its line, so you keep the public business number. You choose continuous coverage, unanswered-only, or after-hours forwarding. Best for SMBs that cannot staff every ring; limit: outbound dialling and automated calling campaigns are out of scope.

Per call reason you define questions, business facts the bot may share, and priority rules. The assistant extracts contact details, repeats critical fields, and builds an intent-tagged ticket. Useful when emergencies, bookings, and sales calls must not share one script; answers outside your configured facts are supposed to be declined rather than invented.

Configured reasons can offer or force transfer to a named teammate when available. If nobody accepts, the bot continues, captures the request, and escalates context for callback. Fits practices and field teams that want humans only for the hard cases.

With Google Calendar or Outlook connected, the assistant checks allowed availability, proposes a slot, and writes the event with caller context. Also supports sending an external booking link by SMS or email. Appointment sync is part of the core commercial model; confirm plan inclusion on the vendor pricing page.

Each handled call produces a dashboard card with summary, full transcript, priority, and next action, plus email and optional SMS notifications. CSV export and multi-user roles support follow-up without replaying voicemail. Transcript retention defaults to a rolling year and is configurable.

Qualified call payloads can flow to CRM, Slack, or Sheets via Zapier or webhooks, and authorised call data can be queried from a ChatGPT connector. Suited to teams that already automate ops; Zapier is documented as available from the Pro tier upward.

Best fit when

  • French or EU SMBs whose revenue still depends on inbound phone calls
  • Field and clinic teams that need after-hours or overflow coverage without hiring a full receptionist
  • Buyers who want configurable intents, human transfer rules, and structured tickets with transcripts
  • Teams ready to connect Google Calendar or Outlook for booking during the call
  • Organisations that can accept Twilio, Stripe, and OpenAI-class subprocessors under SCCs

Poor fit when

  • Enterprises needing a full omnichannel helpdesk (chat, email, in-app) comparable to Intercom
  • Procurement that requires EU-only subprocessors with no US-group cloud, telephony, or model providers
  • Buyers who need self-hosted or fully on-device voice AI
  • Use cases centred on outbound calling, diallers, or automated prospecting campaigns

Consider instead when

  • When: You need omnichannel customer messaging and helpdesk workflows rather than phone reception

    Consider: Intercom (US incumbent in catalog)

    Different product class: support suite vs AI receptionist

  • When: You mainly need meeting or interview transcription with optional on-device processing

    Consider: LiteScribe or HappyScribe

    Speech-to-notes tools, not live call answering

  • When: You need bulk SMS, WhatsApp, or voice messaging APIs for campaigns and OTP

    Consider: Afilnet

    Messaging API platform, not an AI front desk

No known US parent. CLOUD Act exposure rated medium because core telephony, payments, and model subprocessors are US-group entities even though application hosting is described as AWS Paris. Indicative only, not legal advice.

Considerations & known limitations

  • MediumUS-group telephony, payments, and AI providers

    Even with AWS Paris application hosting, Twilio, Stripe, and OpenAI-class providers process call or account data paths. Sovereignty-sensitive buyers must review SCCs and whether voice audio leaves the EU.

  • MediumNo public independent audit package

    Security claims (encryption, pen tests, AWS ISO) are first-party. Request audit reports, pen-test summaries, and a signed DPA before handling sensitive caller data.

  • MediumAI qualification and transcription errors

    Terms explicitly warn that AI may misinterpret calls. Critical medical, legal, or emergency workflows still need human escalation rules and monitoring.

  • LowYoung company / thin public assurance trail

    Entity is newly registered (2025 to 2026). Expect lighter public cert history than long-established EU SaaS vendors; validate financial and support commitments in procurement.

Open questions for due diligence

  • Will Kalyvox sign your DPA and provide a current subprocessor list with regions for voice audio and transcripts?
  • Which exact model providers process live audio versus anonymised text, and can processing be limited to EU regions?
  • Are independent pen-test or ISO/SOC reports available under NDA?
  • What fair-use or concurrency limits apply on each plan for simultaneous inbound calls?

Questions Fréquemment Posées

Yes, according to product and help docs. You forward your current line to the Kalyvox number using permanent or conditional forwarding (unanswered or outside hours). Carrier-specific forwarding codes are documented in the help centre. You do not have to port the public number to use the assistant.

The legal notice places the website and application on Supabase with AWS Europe (Paris) eu-west-3. The privacy policy also lists Twilio (US telephony), Stripe (US payments), OpenAI and other AI providers for voice and transcription, plus analytics tools including PostHog on EU endpoints and Google Analytics. International transfers are framed with SCCs. Treat residency as EU-primary application hosting with US-group processing legs, not an EU-only stack.

Terms state the customer is controller for callers and Kalyvox is processor for call processing. A Data Processing Agreement is available on request (not published as a self-serve PDF on the pages reviewed). Ask for the signed DPA and current subprocessor list before production use with personal data.

No. Kalyvox is built for inbound phone reception, qualification, transfer, booking, and ticket handoff. It is not positioned as an omnichannel chat/email/helpdesk suite. Shortlist it when the phone line is the bottleneck; keep or choose Intercom-class tools when you need multi-channel support operations.

Vendor feature copy states the assistant does not improvise beyond configured business information, does not give medical/legal/technical advice, does not place outbound prospecting calls, and discloses that it is AI when asked. Terms also warn that AI qualification and transcription can err, with liability capped relative to fees paid.

Public pricing describes a monthly subscription plus per-minute usage, with a short free trial that does not require a credit card. Seat and number limits differ by plan tier; appointment booking and calendar sync are called out as included from the entry plan, while Zapier starts on a higher tier. Confirm current figures and fair-use terms on the official pricing page.
