Comparing AI phone assistants is harder than it looks. One bills per month, another per year, a third in credits, a fourth at a flat rate. A feature can be live, available on request, or still on the roadmap.
So here are eight providers active in Switzerland, side by side, with only what each one publishes. We are one of them: check our reading against the links. “Not stated” means the provider says nothing, which is not the same as “no”.
The eight providers
- Voko (Bern). A self-serve assistant for small businesses, built from the business’s own website.
- Suisse Line (Berikon AG; formerly Suisse Voice). A no-code platform for inbound and outbound voice agents; it says it handles Swiss German dialects. Voko against Suisse Line.
- Rednea (formerly Fonea; Lachen SZ). An assistant set up for you, with outbound calls on higher plans. Voko against Rednea.
- Botts AI (Zug). A general AI-agent platform: phone, website chat, internal assistant. Voko against Botts AI.
- Linea (France). A reception service for French-speaking Switzerland that takes requests rather than booking. Voko against Linea.
- CiaoSepp (Baar ZG). A self-serve assistant with a German-language site and many features marked “coming soon”. Voko against CiaoSepp.
- CleverAI (Winkel ZH). One flat-rate plan, set up for you; no calendar, dashboard or recording by design. Voko against CleverAI.
- AWoice (Schlieren ZH). Set up by hand for German-speaking hairdressers, restaurants and physiotherapists. Voko against AWoice.
Prices side by side

|---|---|---|---|---|
| Voko | CHF 99 a month, excl. VAT | 500 | CHF 0.20 | CHF 0.35 per extra minute on Starter, CHF 0.25 on Pro, CHF 0.20 on Business, total rounded up to the franc |
| Suisse Line | CHF 1,980 a year | 100 | CHF 1.65 | From CHF 0.39 a minute |
| Rednea | CHF 90 a month, excl. VAT | 300 | CHF 0.30 | Same price per minute as the plan |
| Botts AI | CHF 169 a month, excl. VAT (Business) | Not stated (credits) | Not comparable | Credit packs, price not stated |
| Linea | CHF 149 a month, excl. VAT | 300 | CHF 0.50 | CHF 0.30 a minute |
| CiaoSepp | CHF 29 (Lite) or CHF 99 (Starter), excl. VAT | 50 or 500 | CHF 0.58 or CHF 0.20 | None on Lite; CHF 0.40 on Starter |
| CleverAI | CHF 249 a month, excl. VAT, flat rate | No minute count (fair use) | Not comparable | None, no minute pricing |
| AWoice | CHF 189 a month (Standard) | 500 | CHF 0.38 | CHF 0.30 a minute |
Botts AI also sells a CHF 19 Personal plan, but it has no phone and no website channel, so the cheapest plan that answers calls is Business.
| Setup fee | Minimum term and notice | Money-back clause | |
|---|---|---|---|
| Voko | None | Monthly; cancel any time, effective at the end of the paid month | None |
| Suisse Line | Not stated on its site | Billed yearly; its own pages disagree on term and notice | Not stated; its terms call loaded credit non-refundable |
| Rednea | None | No minimum; 30 days to month end | None |
| Botts AI | None stated | No minimum; cancel by end of the billing period | None |
| Linea | None | No minimum beyond the paid period; no pro-rata refund | None stated |
| CiaoSepp | None on standard plans | Open-ended; monthly plans end at month end | 30 days, in writing |
| CleverAI | From CHF 490 (CHF 750 on its practices page); waived if you leave within 14 days | No minimum; 30 days' notice | Not stated on its site |
| AWoice | CHF 490 (Standard), CHF 690 (Plus) | 3 months minimum, then 30 days to month end | 30 days |
| Next plan up | Top plan | |
|---|---|---|
| Voko | CHF 299, 1,500 min, CHF 0.20 | CHF 599, 3,000 min, CHF 0.20 |
| Suisse Line | None published | Enterprise, on quote |
| Rednea | CHF 290, 1,000 min, CHF 0.29 | From CHF 590, from 5,000 min, about CHF 0.12 |
| Botts AI | CHF 699 (Business Pro), 30,000 credits | Enterprise, on quote |
| Linea | CHF 350, 1,500 min, CHF 0.23 | CHF 590, 3,500 min, CHF 0.17 |
| CiaoSepp | CHF 299, 1,500 min, CHF 0.20 | CHF 599, 3,000 min, CHF 0.20 |
| CleverAI | No other plan | Add-on: live transfer, CHF 99 a month |
| AWoice | CHF 249 (Plus), 1,000 min, CHF 0.25 | Plus is the top plan |
Voko’s plans differ in features as well as minutes. Starter has the core: answering, booking, call summaries, opening hours with holidays, voicemail, one transfer number and the data controls. Pro adds appointment reminders, contacts with caller recognition and routing, several transfer destinations with a team directory, and bexio. Business adds the API and webhook, booking in your own system, number porting and priority support. The knowledge the assistant reads in full grows with the plan: 40,000 characters on Starter, 100,000 on Pro, 200,000 on Business. The free trial shows everything except porting. Where a table below says “from Pro” or “Business only”, Starter does not have it, so compare a competitor’s entry plan with Starter, not with Pro.
A worked example: a business with 400 minutes of calls a month, over the first three months, VAT excluded:
| How it adds up | First three months | |
|---|---|---|
| Voko | 3 × CHF 99; 400 is inside the 500 included | CHF 297 |
| Suisse Line | CHF 1,980 yearly, plus 3 × 300 extra minutes at CHF 0.39 or more | From CHF 2,331 |
| Rednea | 3 × (CHF 90 + 100 extra minutes × CHF 0.30) | CHF 360 |
| Botts AI | Billed in credits, no minute count | Not comparable |
| Linea | 3 × (CHF 149 + 100 extra minutes × CHF 0.30) | CHF 537 |
| CiaoSepp | 3 × CHF 99 (Starter); 400 is inside the 500 included | CHF 297 |
| CleverAI | 3 × CHF 249 + setup from CHF 490; flat rate, fair use | From CHF 1,237 |
| AWoice | 3 × CHF 189 + CHF 490 setup; 400 is inside the 500 included | CHF 1,057 |
Linea says it charges no Swiss VAT because its billing company is American (its terms). AWoice states no VAT position on its price pages and says it is not VAT-registered: ask for the final figure in writing.
Feature by feature
For Suisse Line we also add what we saw in the console of a test account on 28 September 2026. That is not on its public pages and cannot be linked.
Languages and Swiss German
| Languages | Swiss German | Switches language mid-call | Voices | |
|---|---|---|---|---|
| Voko | Six to choose from (French, German, English, Italian, Spanish, Portuguese), over 30 understood | Speaks it, as a beta; understanding not measured | Yes, across six languages (not in Swiss German) | Up to 6 per language; one for Swiss German |
| Suisse Line | Swiss German, German, French, Italian, English | Speaks and understands, all dialects (claim) | Not stated on its pages; its AI-readable file claims it | Chosen at setup; number not stated |
| Rednea | German, French, Italian, English, Spanish, Swiss German | Speaks and understands (claim); advises a test call for strong dialects | Yes, automatic | 30 listed; its pricing says "over 10" |
| Botts AI | English, German, Italian claimed; French as a call setting | Not stated on its site | Yes, automatic | 8, all English-language accents |
| Linea | French, German, Italian, English | Not stated on its site | Yes, claimed | Several; number not stated |
| CiaoSepp | Swiss German, German, French, Italian, English | Understands all common dialects, answers in dialect or standard German (claim) | Not stated on its site | 2 (Sepp, Lena); more on higher plans |
| CleverAI | Swiss German and "over 50" others | Speaks and understands (claim) | Yes, after the greeting | Not stated on its site |
| AWoice | German only; other languages get a callback note | Understands it, does not answer in dialect | Not stated on its site | Not stated on its site |
Suisse Line, Rednea, CiaoSepp and CleverAI claim Swiss German without a beta label or a published figure. Voko calls it a beta: it speaks it, and does not claim to understand it. AWoice does the opposite: it understands dialect but does not answer in it. Voko offers six languages to choose from and switches between them live. It also lets you upload a recorded greeting. The Suisse Line console showed the same in a test account; no other provider states it.
Booking and calendar
| Books during the call | Which calendar | Moves or cancels | Reminders | |
|---|---|---|---|---|
| Voko | Yes | Cal.com (it connects Google, Outlook and others) on every plan, or your own system through an API (Business only) | Only appointments it booked, from the same number | From Pro: SMS, or a call from the assistant (calls are new) |
| Suisse Line | Yes | Google, Microsoft 365, Calendly; others on request | One industry page says yes; elsewhere not stated | Reminder calls; SMS not stated |
| Rednea | Via Cal.com; its help page lists in-call booking as in development | Google and Outlook via Cal.com; eTermin; Calendly on request | Yes, via Cal.com (claim) | Claimed; setup not documented |
| Botts AI | Cal.com only, set up by Botts; self-service "to follow" | Cal.com | No; changes go through the invite email | Not stated on its site |
| Linea | No: takes requests | Calendly optional; others on quote | No: noted only | Not stated on its site |
| CiaoSepp | Coming soon | Google and Outlook planned | Not stated on its site | Not stated on its site |
| CleverAI | No, on purpose; SMS with a link to your booking tool | Your existing booking tool | Not stated on its site | Not stated on its site |
| AWoice | Yes | Google Calendar; others on request, its pages differ | Yes, by phone | No reminders |
Voko needs Cal.com as the middle layer (a free account, on every plan) or your own system through its API (Business only). It has no direct Google Calendar link, whereas Suisse Line and AWoice connect Google directly. Voko documents reminders by both SMS and call, from Pro; Suisse Line mentions reminder calls, and Rednea claims reminders without a setup guide.
Transfers, opening hours and voicemail
| Transfer to a person | Opening hours | Voicemail or message | Busy line, blocking, caps | |
|---|---|---|---|---|
| Voko | One number on every plan; from Pro, up to 10 rules: a number, a team member, another assistant, or by name | Per weekday, holidays of all 26 cantons, closures with their own message | Audio voicemail up to 2 minutes, by email; no transcript | Backup number when busy; per-number limits, auto-block, daily caps; forward-all switch |
| Suisse Line | Yes, by rules; detail not stated | Agent knows your hours; schedule and holidays not stated | Not stated on its site | Not stated on its site |
| Rednea | Yes, by topic and by language | Free text per day; holidays and closures not stated | Message by email; audio voicemail not stated | Via your carrier only |
| Botts AI | Yes, since 1 October; up to 10 people | Hours only inside transfer rules | Form submission | Not stated on its site |
| Linea | Yes, several destinations by reason | Per day and site, with a closed message; holidays not stated | Takes messages | Via your carrier; two simultaneous calls |
| CiaoSepp | Coming soon | Basic hours, four answering modes; holidays not stated | Takes a task; no voicemail named | Not stated on its site |
| CleverAI | Yes, as a CHF 99 a month add-on | Closure dates and stand-in contacts; the caller hears who to call | Takes the message; no audio kept | Not stated on its site |
| AWoice | No; it says so plainly | Set at onboarding; always answers | No voicemail; a callback note | Not stated on its site |
On what is published, Voko has the most detailed set, with the several-destination transfer rules from Pro (Starter keeps one transfer number). Suisse Line’s public pages say little, but its console in a test account (28 September 2026) showed hours modes with Swiss holidays by canton, overflow forwarding, forwarding to another assistant, and per-number limits with auto-block and daily caps. That is close to Voko’s. AWoice says outright that it does not transfer; CiaoSepp announces it.
Contacts and caller memory
| Recognises returning callers | Past calls as context | Per-contact routing | Contact import | |
|---|---|---|---|---|
| Voko | From Pro: yes, for saved contacts (by caller ID) | From Pro, optional: the last 3 calls | From Pro: yes, straight to you or to another assistant | From Pro: CSV, Excel, bexio |
| Suisse Line | "Conversation memory" (claim) | Same line; depth not stated | Not stated on its site | Outbound lists only |
| Rednea | Claimed; no setup guide | Not stated on its site | Not stated on its site | Not stated on its site |
| Botts AI | Yes, opt-in memory per agent | Opt-in chat history | Not stated on its site | Not stated on its site |
| Linea | Not stated on its site | Not stated on its site | Not stated on its site | Not stated on its site |
| CiaoSepp | Not stated on its site | Not stated on its site | Not stated on its site | CSV and Excel |
| CleverAI | No, by design: every call starts from zero | No | Not stated on its site | Not stated on its site |
| AWoice | Not stated on its site | Not stated on its site | Not stated on its site | Not stated on its site |
Voko publishes the most here, all of it from Pro: Starter has no contacts. The Suisse Line console showed caller identification, VIP routing and call history too. CleverAI has no memory on purpose, as a privacy feature. Two providers say nothing at all.
Knowledge the assistant learns from
| Website | Files | Scheduled re-read | |
|---|---|---|---|
| Voko | Yes: a page, three levels or a sitemap | PDF, Word, text, HTML; 10 MB each, 20 per assistant; read in full up to 40,000 / 100,000 / 200,000 characters (Starter / Pro / Business) | Weekly or monthly |
| Suisse Line | Yes, crawling | PDF, Word, text; limits not stated | Not stated on its site |
| Rednea | Read at setup | Not stated on its site | Not stated on its site |
| Botts AI | Yes, crawling | PDF, Word, text, Markdown; 100 MB each | Daily, weekly or monthly |
| Linea | Not stated on its site | Not stated on its site | Not stated on its site |
| CiaoSepp | Read at setup | Coming soon | Not stated on its site |
| CleverAI | CleverAI sets it up from your site | Not stated on its site | Not stated on its site |
| AWoice | An onboarding form; website not stated | Not stated on its site | Not stated on its site |
Voko and Botts AI are the only two that document both file upload and scheduled re-reads; at Voko both are on every plan, and only the amount of knowledge the assistant reads in full depends on the plan. CiaoSepp lists documents as “coming soon”.
Summaries, transcripts and recordings
| Summary after each call | Transcript | Audio recording | Call list and export | |
|---|---|---|---|---|
| Voko | Email, optional SMS, optional webhook (Business only); reason, urgency, callback | Yes | Off by default; announced when on | Search; CSV and Excel export |
| Suisse Line | Email, also SMS or ticket | Yes | Optional; default not stated | Live statistics; search and export not stated |
| Rednea | Email; SMS contradicted by its help page | Yes | On by default; can be switched off | Call list; search and export not stated |
| Botts AI | No per-call summary stated; form submissions | Yes | Off by default | Search; JSON, CSV and Excel export |
| Linea | Email or SMS, with urgency | Yes | On by default, announced to the caller | History and usage; export on request |
| CiaoSepp | Email plus a morning overview; SMS coming soon | Yes | Optional; default not stated | Dashboard; export not stated |
| CleverAI | One email, then discarded | None | None, no option | No dashboard |
| AWoice | Not stated on its site | Kept 90 days; access not stated | None | No dashboard |
Recording is off by default at Voko and Botts AI, on at Rednea and Linea, and absent at CleverAI and AWoice. Those two treat “no audio is kept” as a feature; the cost is that you cannot listen back to a call.
Integrations, API and webhooks
| CRM and accounting | Webhooks and API | Zapier, Make, custom tools | Website chat or voice widget | |
|---|---|---|---|---|
| Voko | bexio from Pro (contacts, call notes); no native CRM | Business only: signed after-call webhook, no retry; booking contract with OpenAPI file; no API to read calls | No native apps; the webhook could feed them, undocumented | Chat widget (beta); no voice widget |
| Suisse Line | HubSpot, Salesforce, Pipedrive, Zendesk; bexio listed | Webhooks; REST API, docs behind login | Zapier, Make, n8n, custom tools during calls | Not on its public pages (console: voice widget and chat) |
| Rednea | HubSpot, bexio on request | API on its top plan; docs not found | Logos only; custom tools as a paid add-on | Webchat, marked "new", undocumented |
| Botts AI | No named native connector | No public API (its docs say so) | MCP and HTTP tools | Chat widget with optional voice |
| Linea | On quote | API on quote | Zapier on quote | Not stated on its site |
| CiaoSepp | Not stated on its site | Webhook and API coming soon (top plan) | HTTP tools coming soon; Zapier not stated | Not stated on its site |
| CleverAI | Not stated on its site | Not stated on its site | Not stated on its site | Not stated on its site |
| AWoice | Not stated on its site | Not stated on its site | Not stated on its site | Not stated on its site |
Suisse Line is clearly ahead on breadth: named CRMs, a REST API, Zapier, Make, n8n and custom tools. Voko has bexio (from Pro) and a signed webhook (Business only), but no native CRM and no REST API. CiaoSepp’s webhook, API and HTTP tools are all “coming soon”.
Phone numbers
| New Swiss number | Keep your own number | Porting | Numbers per plan | |
|---|---|---|---|---|
| Voko | Included, from a pool; no choice of area code | Yes, codes per carrier | Business only: on request, manual, about four weeks, landlines | 1 / 3 / by agreement |
| Suisse Line | Area code selectable; cost not stated | Yes | Not stated on its site | Not stated on its site |
| Rednea | 1 included at setup | Yes, the core model | Not offered or described: you forward instead | 1 / 5 / custom |
| Botts AI | Swiss or US number, from Business | Not stated on its site | Not stated on its site | 1 / 2 / custom |
| Linea | Swiss number part of the service | Yes | Not stated on its site | Not stated on its site |
| CiaoSepp | Swiss number on every plan | Yes | Not stated on its site | Not stated on its site |
| CleverAI | A forwarding number; cost not stated | Yes | Not stated on its site | Not stated on its site |
| AWoice | Not stated on its site | Yes | Not stated on its site | Not stated on its site |
Suisse Line lets you choose the area code; Voko does not. Voko is the only one that publishes a porting process, and a slow one, on Business only.
What each says about your data
These are each provider’s own statements, not checks of ours:
- Voko: our database is in Zurich and our application in Frankfurt; voice, language model and telephony run through US providers. We do not claim Swiss hosting. A zero-retention mode stores nothing.
- Suisse Line says all data is stored in Switzerland and that it is ISO 27001 certified. It names no voice, language-model or telephony provider.
- Rednea says stored data stays in Switzerland; live processing runs at Google, OpenAI and Telnyx, American companies whose location it gives as “global”.
- Botts AI says its infrastructure is in Switzerland. Calls run through Twilio in the United States, and its pages name different regions for voice processing.
- Linea says Frankfurt, with Google Gemini and Twilio in the United States. Its privacy policy says audio is kept 30 days, its security page six months.
- CiaoSepp says primary storage is in Switzerland; its voice AI is Google Gemini, its telephony Telnyx, a US company.
- CleverAI says its app runs in Amsterdam, telephony and language models come from US providers, and it does not claim data stays in Switzerland.
- AWoice says its server is in Frankfurt and speech processing happens at US providers (Vapi, Soniox, OpenAI, Twilio).
| Recording by default | Retention stated | Data processing agreement | Certification | |
|---|---|---|---|---|
| Voko | Off | 1, 7, 30 (default), 90 days or never | On request | None |
| Suisse Line | Not stated on its site | Recordings 90 days | On request | ISO 27001 (claim) |
| Rednea | On | 7, 30, 90 days or contract term | Public | None stated |
| Botts AI | Off | No fixed period stated | Enterprise or EU customers, on request | None stated |
| Linea | On, announced | Its documents disagree | Public | None claimed |
| CiaoSepp | Not stated on its site | No figure given | Public | None stated |
| CleverAI | Nothing recorded | Summary sent once, then discarded | No public document | None stated |
| AWoice | Nothing recorded | Up to 90 days | On request | None stated |
Setup and trial
| Who sets it up | Claimed time to go live | Free trial | Onboarding help | |
|---|---|---|---|---|
| Voko | You, from your website | No fixed time promised | 7 days or 30 minutes, no card, every feature except porting | Guides and a checklist; no personal call |
| Suisse Line | You; optional consulting | "Live in minutes" | CHF 20 of credit, no card | 1 hour of consulting in Starter |
| Rednea | Rednea for you, then you edit | "Ready in 30 minutes" | None; free demo | Free 20-minute consultation |
| Botts AI | You | Under 15 minutes for most | 14 days, no card (150 of 1,500 credits usable until you add a card) | On Business Pro only |
| Linea | You, guided by Linea | "10 minutes", it says | 7 days, card required | First call checked together |
| CiaoSepp | You | "15 minutes" | None; free demo call | On higher plans only |
| CleverAI | CleverAI for you | "Within 24 hours" | 14 days, no card | Personal training included |
| AWoice | AWoice, by hand | No fixed claim | None; free 20-minute demo | Included; log review for 30 days |
Five of the eight offer a trial, and Linea is the only one that asks for a card. Rednea, CiaoSepp and AWoice offer a free demo instead.
Which one for which business
- Swiss German is central and you want the broadest toolbox. Suisse Line: CRMs, API, Zapier, outbound. It is also the most expensive per included minute, and its pages disagree on the contract.
- Modest call volume and someone to set it up. Rednea Basic, CHF 90 for 300 minutes, with a free consultation.
- You also want website chat and an internal assistant. Botts AI.
- French-speaking Switzerland, requests rather than bookings. Linea, with 3,500 minutes for CHF 590 at the top.
- Taking messages and flagging urgent calls is enough today. CiaoSepp, with a 30-day money-back clause. Booking and transfer are still “coming soon”.
- A practice that wants nothing stored. CleverAI, flat CHF 249, with no calendar and no dashboard.
- A German-speaking hairdresser, restaurant or physio on Google Calendar. AWoice: booking into the calendar, no transfer, a three-month minimum.
- Many minutes, booking, transfers, hours and contacts in several languages, self-serve. Voko: about CHF 0.20 a minute and a trial with no card. Contacts, reminders and several transfer destinations come from Pro (CHF 299). Booking needs Cal.com or, on Business only, your own system.
Before you sign anywhere: divide the price by the minutes, read the price of extra minutes, check whether billing is monthly, yearly, in credits or flat, and listen to a real call. You can hear ours right now: enter your website and talk to an assistant built from it. For the full arithmetic, including the human alternatives, read how much an AI phone assistant costs.
