The panel's verdict
sipgate is a German cloud telephony platform — cloud PBX, SIP trunking, contact centre and mobile — from sipgate GmbH of Düsseldorf. Scoring is clearest on sovereignty, where scores cluster at 8, the highest mark given: a German contracting entity, hosting exclusively in Germany on ISO 27001-certified data centres in Frankfurt and Düsseldorf, and a published data processing agreement committing processing to the EU and EEA unless the user consents, with subprocessors named by location. The contact centre scores 6-7 on skills-based routing, a real-time dashboard and a 24/7 AI agent that transcribes and summarises calls. Evidence runs thinnest on apps and devices, with no public information found on desk-phone models or provisioning. Judges split on pricing transparency: business S, L and XL are public at 12.95, 17.95 and 22.95 Euro per user per month from two users, but contact-centre seats, numbers, devices and the Teams add-on carry no public price, so an annual bill is not computable. Calling and routing splits over porting timelines, on which no public information was found.
Speaks for it
- Hosting exclusively in Germany on ISO 27001-certified data centres in Frankfurt and Düsseldorf, with the Bundesnetzagentur as supervisory authority
- A published data processing agreement commits processing to the EU and EEA unless the user consents, with a subprocessor annex naming each provider's location, including the AI services Microsoft Ireland, Google Cloud EMEA in Ireland and Mistral in France
- Contact-centre routing by availability, service level or skills, a real-time service-level dashboard, listen-in coaching and a 24/7 AI agent with automatic transcripts and summaries are all documented
- Business plans are published at 12.95, 17.95 and 22.95 Euro per user per month with a two-user minimum, no setup fee and cancellation at one working day's notice to month end
- Emergency calls to 110 and 112 transmit the customer's stored address, and premium-rate number ranges are blocked by default
Held against it
- We found no public information on supported desk phones or DECT models, automatic provisioning, or devices sold or rented
- The captured pages carry no public price for contact-centre seats, numbers, devices or the Teams add-on, and the Enterprise plan is quote-only
- The stated 98 percent SIP-server availability is published without credits, and we found no public incident history
- Administration is documented with administrator and user account levels; we found no public information on SCIM provisioning, audit logs or bulk user import
- The captured pages give different figures for whether call encryption is standard or optional, and for API costs
Best for
- You need German-hosted telephony with a published data processing agreement and a subprocessor annex naming each provider and its location
- You run an inbound team that wants routing by availability, service level or skills, a real-time dashboard and a 24/7 AI agent inside the phone system
- Your staff already work in Microsoft Teams or keep a VoIP-capable PBX — real Teams telephony and SIP trunking are documented without additional hardware
- You want published per-user plans from two users with a 30-day free and non-binding trial and monthly cancellation
Avoid if
- You must compute a full annual cost before signing — per-minute rates are published only as floors such as "ab 0,5 ct/min" and the Enterprise plan is quote-only
- You need desk phones from named makers with automatic provisioning — the captured devices pages document apps rather than hardware
- Your security review requires call encryption on by default — the service description makes encryption of calls and faxes optional
- You need an availability commitment backed by credits — ask the vendor: the public pages we read do not show it

How this is scored
What the phone system does with a call: local geographic numbers in the customer's own area code and in other countries, number blocks and porting of existing numbers, extensions, IVR menus, queues, ring groups and hunt groups, time-based and holiday routing, call forwarding and transfer, voicemail to email, fax to email, conference calls, call recording, call park and pickup, busy lamp fields, caller ID per user or team, and emergency calls (110 and 112) with the caller's location.
0 — Places no phone calls on the public telephone network; a chat or meeting tool with internal calling only.
3 — Phone numbers and extensions with forwarding and voicemail; IVR, queues, time-based routing and porting are basic or not described.
5 — Local numbers in the customer's area code with porting documented, IVR menus, queues and ring groups, time-based and holiday routing, voicemail to email, call transfer and pickup, call recording, fax or fax to email, and emergency calling described.
8 — Number blocks and international numbers in many countries, a visual call flow editor, skills or priority routing, call park and busy lamp fields, recording rules per user or queue with consent announcements, emergency calls with a registered location per user or site, and the porting process and its timelines documented.
10 — Call handling a large multi-site company runs on: every feature above with number provisioning and porting by API, routing by caller data from the CRM, location-aware emergency calling for home offices, and the full feature set documented per plan with its limits.
The Office Manager
German local numbers from our own area code, free number porting, multi-level voice menus, a waiting queue, call groups, busy lamp fields, voicemail forwarded to email, fax and emergency calls to 110 and 112 using our stored address are all documented — that covers almost everything our switch-off deadline needs. Before signing, though, I found no public information on the porting process and its timeline, on number blocks, call park or pickup, which is precisely the gap that worries me with a number that has been on our letterhead for thirty years. 3 8 15 17 24
The IT Administrator
Local numbers in our own area code, porting described as free, multi-level IVR menus that route by location or concern, queues, call groups, voicemail with email forwarding, fax and busy lamp fields are all documented, and skills-based routing appears in the contact centre module. Emergency calls to 110 and 112 are described with the customer's registered address, but I found no public information on location-aware emergency calling for home-office users, on call park, on number blocks, or on the porting process and its timelines. 3 4 8 15 17 24
The Contact Centre Lead
German local numbers in our own area code, free number porting and international numbers are documented, alongside multi-stage IVR menus that route to groups, waiting fields, busy lamp fields, call groups, transfer, voicemail to email, web fax, and 110/112 emergency calls that pass the stored address to the rescue centre. Skills-based routing appears within the contact centre module, and the visual routing pages cover channels, numbers and forwarding. We found no public information on number blocks, call park, or the porting process and its timelines. 2 3 5 8 15 24
The Inside Sales Lead
German local numbers from our own area code, free porting of existing numbers, multi-level IVR menus, queues, ring groups, voicemail to email and a call recorder at 3 ct./min are all documented, and emergency calls to 110 and 112 go out with the customer's stored address. International numbers from many countries and a visual routing builder push this above the middle of the scale. We found no public information on time-based and holiday routing, call pickup, number blocks or porting timelines. 2 3 8 15 24
The Data Protection Officer
German local numbers in the customer's own area code with free porting, multi-stage IVR menus, hold queues and call groups, busy lamp fields, voicemail to email, web fax and 110/112 emergency calls routed with the customer's registered address are all documented, and international numbers, a visual routing set-up and skills-based routing in the contact centre push past the base level. We found no public information on time-based and holiday routing, call park, number blocks, or the porting process and its timelines, so the evidence sits between the levels. 2 3 8 15 17 24
The Skeptic
German local, mobile and international numbers, multi-stage IVR menus that link by location or concern, queues, busy lamp fields, fax, voicemail to email, transfers and 110/112 calls carrying the customer's address are all documented, and number porting in is advertised as free. We found no public information on number blocks, porting timelines, call park, conference calls, consent announcements for the per-minute recording, or the terms for taking numbers back out — so the port-in promise is easier to verify than the port-out. 2 3 4 8 15 24
Apps, desk phones & Microsoft Teams

Show reasoningHide reasoning
How this is scored
Where the calls are made and taken: desktop and mobile softphone apps, a browser client, presence, desk phones and DECT handsets from named makers (Yealink, Snom, Gigaset, Poly, Cisco) provisioned automatically, devices for sale or rent, the mobile phone as an extension with the company number shown, fixed-mobile convergence, Microsoft Teams calling through Direct Routing or Operator Connect, headset support, and the apps' ratings and update notes.
0 — No app and no device support; calls only through hardware the customer configures by hand.
3 — A softphone or mobile app; desk phones, Teams calling and the company number on mobile are basic or not described.
5 — Desktop, mobile and browser apps with presence, desk phones from named makers provisioned automatically, the company number shown on outgoing mobile calls, call handover between devices, and a Microsoft Teams integration or connector.
8 — A list of supported desk and DECT phones with auto-provisioning documented, devices sold or rented, Microsoft Teams calling through Direct Routing or Operator Connect with certification stated, fixed-mobile convergence with a SIM or mobile network, and app features documented per platform.
10 — Every endpoint a workforce uses, managed from one place: desk, DECT, mobile, browser and Teams with feature parity stated, device fleet management and firmware updates from the portal, and the app's accessibility and offline behaviour documented.
The Office Manager
The sipgate app for various operating systems with status display, the office number shown when calling from the mobile, parallel ringing of the VoIP phone and the mobile, and real telephony inside the Microsoft Teams clients without extra hardware are documented, along with an own mobile network with SIM, eSIM and MultiSIM. However, I found no public information on which desk phones from which makers are supported, how they would be provisioned, or whether devices can be bought or rented — and keeping our existing desk phones is exactly what I need to be sure of. 2 3 5 17 24
The IT Administrator
Desktop and mobile apps with presence and status, the office number shown when calling from the mobile, and fixed-mobile convergence through sipgate's own mobile network with SIM, MultiSIM and a free eSIM are well documented, and real telephony in all Microsoft Teams clients over our existing numbers is described. What I could not find is any list of supported desk or DECT phones with automatic provisioning — decisive for our production halls — and we found no public information on devices sold or rented, or on the Teams connection route such as Direct Routing or Operator Connect. 2 3 8 17
The Contact Centre Lead
The pages document desktop and mobile apps with status display and call statistics, the office number on outgoing mobile calls, parallel ringing on desk phone and mobile, a free eSIM and MultiSIM on the mobile network operated with Telefónica Germany, and real telephony in all Microsoft Teams clients through sipgate trunking without additional hardware. We found no public information on supported desk phone or DECT models with automatic provisioning, on device sale or rental, or on a Direct Routing or Operator Connect certification behind the Teams calling. 2 3 5 8 17 18 24
The Inside Sales Lead
The mobile app showing the office number on outgoing calls from a rep's own phone, parallel ringing on desk phone and mobile, a presence status display and iOS/Android apps are documented — exactly what my reps need walking a trade-fair booth — with an eSIM on the Telefónica Germany network. Telephony inside all Microsoft Teams clients works through trunking without extra hardware. We found no public information on desk phones from named makers with automatic provisioning, on devices for sale or rent, or on a browser softphone. 2 3 17 18
The Data Protection Officer
iOS and Android apps with presence through shared call lists, the office number shown on outgoing mobile calls, and real telephony inside the Microsoft Teams clients are documented, with fixed-mobile convergence on sipgate's own mobile service over the Telefónica Germany network including SIM, MultiSIM and eSIM. We found no public information on desk phones or DECT handsets from named makers, automatic device provisioning, or devices sold or rented, which caps the level. 2 3 17 18 24
The Skeptic
Desktop and mobile apps with presence, the office number displayed on outgoing mobile calls and real telephony inside all Microsoft Teams clients are documented, and the fixed-mobile side is unusually concrete: a mobile network with Telefónica Germany, eSIM and MultiSIM. We found no public information on desk phones or DECT handsets from named makers, automatic provisioning, device sale or rent, or Teams certification through Direct Routing or Operator Connect — the devices page we captured documents apps, not hardware. 2 3 8 17 18 24

How this is scored
How a team that lives on the phone is run: ACD queues with skills and priorities, agent states and wrap-up time, a wallboard, live monitoring with listen, whisper and barge, callbacks instead of waiting, outbound and power dialers, call statistics and reports per agent and queue, missed-call handling, AI transcription, summaries and sentiment, an AI receptionist or voicebot, and SMS or WhatsApp beside calls.
0 — No queues or call statistics of any kind; calls ring until someone answers.
3 — A simple queue and a call history; agent states, live monitoring, reports and AI features are basic or not described.
5 — Queues with agent log-in and log-out, wrap-up time, a wallboard or live view, call statistics per agent and queue, missed-call lists with callback, call recording for coaching, and AI transcription or summaries offered.
8 — Skills-based routing, listen, whisper and barge, callback in queue, outbound or power dialers, scheduled and exportable reports, AI transcription, summaries and sentiment with the languages listed, an AI receptionist or voicebot, and SMS or messaging channels beside calls.
10 — A contact centre that replaces a separate suite: workforce management and quality scoring, omnichannel routing, real-time AI coaching, and every AI feature documented with its model provider, data handling and an opt-out.
The Office Manager
The contact centre is documented as part of the phone system: routing by availability, service level or skills, a real-time dashboard with call volume, waiting times and reachability, announcements with queue-position hints, listen-in for coaching, agent-filtered statistics plus a paid group-statistics add-on, call recording, and a free AI agent (sipgate sona) answering around the clock and handing over with context, backed by automatic transcripts, summaries and talk-ratio analysis. I found no public information on whisper or barge, callbacks from the queue, outbound dialers, scheduled or exportable reports, or messaging channels beyond SMS. 1 2 4 8 24
The IT Administrator
Skills-based routing, a real-time service-level dashboard, an agent workspace with status and handovers, listen-in coaching and per-agent analytics are documented, alongside automatic transcripts, summaries, topics and talk-ratio analysis, conversation intelligence over one hundred percent of calls, an AI agent that answers and forwards around the clock, and SMS beside calls with group statistics as a paid add-on. I found no public information on whisper and barge, callbacks from the queue, outbound or power dialers, or scheduled and exportable reports. 1 2 4 19 24
The Contact Centre Lead
The contact centre module documents routing by availability, service level or skills, a real-time dashboard for call volume, waiting times and reachability, listen-in coaching for quality assurance, and analytics filterable by individual agents, time windows and topics — most of what my eighteen agents in Leipzig need. AI agents take calls around the clock and hand over with context, transcripts and summaries are created automatically after hang-up, and those summaries can sync into the CRM or a helpdesk such as Zammad, Zendesk or Freshdesk. We found no public information on callbacks from the queue, whisper or barge, wrap-up time, dialers, or the languages the AI transcription supports. 1 2 4 6 19 20
The Inside Sales Lead
Skills-based routing, a real-time service-level dashboard with wait times and reachability, listen-in coaching, statistics per agent and an AI receptionist answering calls around the clock are documented, and after hang-up the AI Assist writes transcripts, summaries, topics and to-dos straight into the CRM. SMS beside calls is priced. We found no public information on a power dialer, callbacks from the queue, whisper or barge, or scheduled and exportable reports — the missing dialer hurts an outbound team like mine. 1 2 4 19
The Data Protection Officer
Skills-based routing, a real-time service-level dashboard, listen-in coaching and an AI agent that answers standard calls around the clock and hands over with context are documented, as are transcripts, summaries, topics, to-dos and talk ratio, agent-filterable analytics, group statistics and SMS beside calls. We found no public information on whisper and barge, callbacks from the queue, outbound or power dialers, or scheduled exportable reports. Credit where due from my chair: the data processing agreement names the summary models — Microsoft Azure AI and Google Gemini in Ireland, Mistral AI in France — and states that with the AI features off there is no processing by Microsoft. 1 2 4 14 19 24
The Skeptic
Skills- and service-level routing, a real-time service-level dashboard, listen-in coaching, queue position announcements, a 24/7 voice agent that answers and hands off with context, and transcription, summaries, tonality analysis and talk ratio are documented, with SMS priced beside calls. We found no public information on whisper and barge, callbacks in queue, dialers, exportable reports or WhatsApp, and the AI languages are not listed. To the vendor's credit the AI chain is disclosed: Microsoft Ireland, Google Cloud EMEA and Mistral in the subcontractor annex, an option to switch to OpenAI, and no processing by the subcontractor when the features are switched off. 1 4 10 14 19 20 24

How the phone system fits the company: integrations with CRM and helpdesk tools (Salesforce, HubSpot, Pipedrive, Zendesk, Microsoft Dynamics) with click-to-call, caller pop-ups and automatic call logging, a documented REST API and webhooks for call events, SIP trunks for an existing PBX and bring-your-own-carrier, an admin portal with roles, single sign-on (SAML) and SCIM, two-factor authentication, multi-site and multi-company set-up, bulk user import, audit logs, and partner or reseller accounts.
0 — No integrations and no administration beyond one login per number.
3 — A web portal to manage users and numbers and one or two integrations; the API, roles and SSO are basic or not described.
5 — Integrations with the common CRM and helpdesk tools with click-to-call and call logging, a documented REST API and webhooks, an admin portal with roles, two-factor authentication, several sites in one account, and SIP trunking or a connection to an existing PBX.
8 — Caller pop-ups and call data written to the CRM record, an API covering users, numbers, routing and call records, single sign-on (SAML) and SCIM provisioning, audit logs, bulk import and templates, partner or reseller accounts with sub-customers, and SIP trunks documented for named PBX systems.
10 — Administration that scales across many sites and companies: every setting reachable by API with parity stated, granular roles per site and team, SSO enforced with SCIM, audit logs exportable to a SIEM, and a partner portal with white-label and separate billing.
The Office Manager
Ready integrations with Salesforce, HubSpot, Pipedrive, Zendesk and Zoho are listed with contacts shown automatically on incoming calls, notes and summaries written back and call logs synchronised, and a REST API with OAuth2 can dial, transfer, hold, record and send SMS and fax, with real-time webhooks for incoming and outgoing calls; there is SIP trunking for an existing PBX, an admin and a user account level, two-factor authentication, and SAML single sign-on on the enterprise plan. I found no public information on SCIM provisioning, audit logs or bulk user import. 2 5 6 8 21 22 24
The IT Administrator
The CRM story is strong: Salesforce, HubSpot, Pipedrive, Zendesk and Zoho among fifty-plus integrations, contacts shown on incoming calls, automatic sync of notes, summaries and call logs, plus a REST API with webhooks, OAuth2 clients and call control including transfer, hold and record. SAML 2.0 single sign-on appears in the enterprise features, which covers our Entra ID login, but administration is described only as an administrator and a user account, and I found no public information on SCIM provisioning, audit logs, bulk import, or API management of users, numbers and routing. 2 6 8 21 22 24
The Contact Centre Lead
More than fifty integrations are listed, including Salesforce, HubSpot, Pipedrive, Zendesk, Zoho Desk, Freshdesk and Zammad, with contacts shown automatically on incoming calls and call notes and summaries written into the CRM, plus a documented REST API with OAuth2 clients and real-time webhooks covering call control, SMS and fax. SAML 2.0 single sign-on, two-factor authentication, two permission levels and a partner programme are stated, and SIP trunking connects existing VoIP-capable PBXs. We found no public information on SCIM provisioning, audit logs, bulk user import or administration across several sites in one account. 2 5 6 8 21 22 24
The Inside Sales Lead
HubSpot, Salesforce, Pipedrive and Zendesk are all listed as integrations, with contacts popping up on incoming calls, call notes and summaries written into the CRM and call logs synchronised — the heart of what my team needs.

How this is scored
Whether the service holds on a bad day and in an audit: redundant data centres and carrier connections, a stated availability or SLA with credits, the vendor's own public status page and incident history, call quality measures (codecs, quality monitoring), encryption of signalling and media (TLS and SRTP), registration as a telecoms provider with the national regulator (Bundesnetzagentur or its EU equivalent), the secrecy of telecommunications, recording consent and retention, emergency call handling for remote users, fraud protection against toll fraud, and security certifications such as ISO 27001.
0 — Nothing on availability, security or the provider's status as a telecoms operator.
3 — A claim of high availability or "German data centres"; encryption, the SLA, the status page and regulatory status are basic or not described.
5 — Redundant data centres named by country, a public status page, TLS and SRTP encryption offered, the provider's registration with the national regulator or the carrier behind the numbers stated, a stated availability, and call recording rules described.
8 — An SLA with credits published, the incident history public, encryption on by default with the protocols documented, ISO 27001 or comparable certification with its scope, toll fraud protection and spending limits, emergency calls from softphones and home offices documented, and retention of recordings and call records stated.
10 — Carrier-grade operation evidenced: geo-redundant platforms with failover tested and published, end-to-end encryption options, independent audits (ISO 27001, BSI C5 or SOC 2) with reports available, and the regulatory and lawful-interception obligations explained in plain language.
The Office Manager
Data centres in Frankfurt and Düsseldorf certified to ISO 27001, TLS and SRTP encryption, a public status page, a stated minimum SIP-server availability of 98 percent averaged over 365 days, the Bundesnetzagentur named as supervisory authority, a security concept under §166 TKG regularly audited by the regulator, emergency calls with our stored address, and 30-day retention for voicemail, fax and events give me reasonable confidence for the deadline weeks. Call encryption is documented as optional rather than on by default, and I found no published SLA with credits and no public incident history. 2 3 10 11 14 23 24
The IT Administrator
Two German data centres in Frankfurt and Düsseldorf with ISO 27001 certification under continuous recertification, TLS and SRTP encryption, AES-256 at rest, a public status page, Bundesnetzagentur as the supervisory authority and a security concept under the Telecommunications Act audited by the regulator give me a solid audit footing, with thirty-day retention for events, faxes, SMS and voicemails stated. The 98 percent SIP-server availability is stated without an SLA with credits, and I found no public information on emergency location handling for home-office softphones or a public incident history. 2 9 10 11 14 24
The Contact Centre Lead
Data centres in Frankfurt and Düsseldorf certified to ISO 27001 with ongoing recertification, a public status page with subscription for outages and maintenance, TLS for signalling and SRTP for media documented, and a stated SIP-server availability of 98 % averaged over 365 days. Emergency calls to 110 and 112 are routed with the customer's stored address, premium number ranges are blocked by default under a prepaid model, and retention of events, fax, SMS and voicemail is stated at thirty days. Telecoms regulation shows through the Bundesnetzagentur as supervisory authority and a §166 TKG security concept regularly audited by it, while we found no public information on an SLA with credits or a public incident history. 2 3 9 10 11 14 23 24
The Inside Sales Lead
ISO 27001-certified data centres in Frankfurt and Düsseldorf, TLS and SRTP encryption plus AES-256 at rest, a public status page, a stated 98 percent SIP server availability, Bundesnetzagentur supervision with a TKG security concept audited by the regulator, and 30-day retention for events, faxes, SMS and voicemails are documented. Premium-rate number ranges are blocked by default. We found no public information on an SLA with credits, a public incident history, or emergency calling from home offices specifically. 9 10 11 14 24
The Data Protection Officer
Two ISO 27001-certified data centres in Frankfurt and Düsseldorf, a public status page, a stated 98 percent SIP-server availability over 365 days, the Bundesnetzagentur named as supervisory authority, a security concept under the Telecommunications Act audited by the regulator, premium-rate ranges blocked by default, and a 30-day maximum retention for voicemails, SMS, faxes and the event list give me most of what an audit of six medical practices needs. The captured service description makes encryption of calls and faxes optional rather than on by default, and we found no public information on an SLA with credits, on consent announcements before recording, or on a retention period for recordings themselves — the exact gap that would worry a practice before enabling recording. 2 9 10 11 14 23 24
The Skeptic
Two ISO 27001-certified data centres in Frankfurt and Düsseldorf with ongoing recertification, a public status page, TLS and SRTP explained in detail, retention periods of 14 to 30 days stated, premium-rate numbers blocked by default, emergency calls with the customer's address, and a TKG security concept regularly audited by the Bundesnetzagentur — more telecoms substance than most cloud vendors publish. But the 98 percent SIP-server availability carries no credits when it slips, we found no public incident history, and the captured pages give different figures for whether call encryption is standard or optional. 2 3 9 10 11 14 23 24

How this is scored
Who the contracting entity and the parent company are, where call records, voicemails, recordings, transcripts, contacts and account data are stored and processed, which carriers carry the calls, and who the subprocessors are (hosting, carriers and number providers, SMS gateways, AI transcription and summary models, email delivery, support and payment tools). Independently sourced by the sovereignty pipeline. International numbers and carriers needed to reach other countries are part of what the product does and are not counted against it; where the data is stored and who processes it is. A self-hosted phone system the customer runs on its own European servers counts as the customer's chain, whatever the vendor's seat.
0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.
3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.
5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (AI transcription, SMS, support, payment) run through non-EU providers without a stated safeguard.
8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated — or a self-hosted edition documented that keeps every record on the customer's own servers.
10 — Sovereign end to end and evidenced: European ownership, entity, hosting, carriers and every subprocessor including the AI models, or a self-hosted edition with no call home, data export and deletion documented, and certifications published with their scope rather than implied.
The Office Manager
Everything that matters to our client data is European and named: sipgate GmbH in Düsseldorf as contracting party, hosting exclusively in Germany on named infrastructure (Myloc in Düsseldorf, Interxion in Frankfurt), a published data processing agreement at no extra fee committing to processing only in the EU/EEA, and a subcontractor annex naming the German carriers and the AI services through Microsoft Ireland, Google Cloud Ireland and Mistral in France, with the assurance that disabled AI features mean no processing by Microsoft. US providers such as HubSpot and ActiveCampaign appear in the privacy policy for website, newsletter and enquiry handling, with EU standard contractual clauses named as the mechanism, and I found no statement on the company's ownership. 3 9 11 13 14
The IT Administrator
The contracting entity is sipgate GmbH in Düsseldorf with the commercial register entry, all infrastructure sits exclusively in Germany on named operators in Düsseldorf and Frankfurt, and the published data processing agreement commits to processing in the EU or EEA and lists its subprocessors with locations — the AI services Microsoft Azure AI and Google Gemini in Ireland and Mistral in France, German telecoms pre-services, and Telefonica Germany behind the mobile network. The privacy policy names marketing and support processors in the USA such as HubSpot, Google and ActiveCampaign with EU standard contractual clauses stated as the safeguard, so the core call chain is European while I found no public information on the parent company or its ownership. 3 11 13 14 24
The Contact Centre Lead
The contracting entity is sipgate GmbH in Düsseldorf (Amtsgericht Düsseldorf, HRB 39841), the infrastructure runs exclusively in German data centres operated by Myloc in Düsseldorf and Interxion in Frankfurt, and the published data processing agreement commits to processing only within the EU or EEA. The subcontractor annex names the chain with its locations: German carriers and pre-services, Pusher (Bird B.V.) in the Netherlands for real-time signalling, and the AI summary services at Microsoft Ireland, Google Cloud EMEA in Ireland and Mistral AI in France. Website-side marketing and support tools run through US providers such as Google and HubSpot under standard contractual clauses, so I do not call the chain sovereign end to end. 2 9 11 13 14 24
The Inside Sales Lead
The contracting entity is sipgate GmbH in Düsseldorf with hosting exclusively in Germany on named data-centre operators (Myloc in Düsseldorf, Interxion in Frankfurt), and the published data processing agreement commits processing to the EU/EEA and lists the subcontractors: the mobile network runs on Telefónica Germany, and the AI transcription chain goes through Microsoft Ireland, Google Cloud EMEA in Ireland and Mistral in France. Marketing, survey and support tools in the privacy policy such as Google, HubSpot, ActiveCampaign and Qualtrics are US providers tied with standard contractual clauses. That is a European chain end to end for the product itself. 3 9 11 13 14
The Data Protection Officer
A German contracting entity at the district court of Düsseldorf (HRB 39841), hosting exclusively in Germany on named operators (Myloc in Düsseldorf, Interxion in Frankfurt), a published data processing agreement at no extra fee with a subprocessor annex naming each provider and its location, EU-only processing unless the customer consents, ISO 27001-certified data centres, and the transcription and summary models named as Microsoft Azure AI and Google Gemini in Ireland and Mistral AI in France — that is close to the full chain. A beta setting can switch the large language model to OpenAI, and the privacy policy lists US providers such as ActiveCampaign, Calendly, Google, HubSpot and Qualtrics for newsletter, booking and support tasks with standard contractual clauses as the safeguard; we found no public information on the ownership structure behind the vendor. 2 10 11 13 14 24
The Skeptic
A German contracting entity in Düsseldorf, hosting exclusively in Germany on named data centre operators in Düsseldorf and Frankfurt, processing committed to the EU and EEA unless the user consents, a published data processing agreement, and a subcontractor annex naming the carriers, the hosting operators and the AI services — Microsoft Ireland, Google Cloud EMEA in Ireland, Mistral in France. The edges of the chain are American: support runs through HubSpot Inc. in the USA and newsletters through ActiveCampaign in the USA, with standard contractual clauses stated as the safeguard, and the language-model setting can be switched to OpenAI, whose location the pages do not state. 2 3 9 11 13 14
Pricing transparency

Show reasoningHide reasoning
How this is scored
Whether a buyer can compute the real annual cost from public pages alone: price per user or extension and per plan, what numbers, number blocks and porting cost, which calls are included in a flat rate (landline, mobile, international) and what the rest cost per minute, which features (call centre, recording, AI, CRM integrations, Teams calling) cost extra, device prices or rent, set-up fees, minimum term and notice period, and VAT.
0 — No public prices at all; every customer is a sales call or a partner quote.
3 — A starting price per user exists, but what numbers, minutes, porting and add-ons cost is unclear.
5 — Plans are public with their price per user and main inclusions, but at least one commonly needed piece (number blocks, porting, international minutes, call centre seats, AI or recording) is unpriced or "on request".
8 — Every plan priced publicly with its scaling rule, a per-minute price list for calls outside the flat rate, numbers, porting and devices priced, add-ons priced, set-up fees, minimum term and VAT treatment stated.
10 — Complete price computability: annual cost derivable for a given number of users, numbers, sites and call minutes, with every add-on, device, porting and support fee and the cancellation and number-export terms published.
The Office Manager
The three business plans are public at 12,95, 17,95 and 22,95 Euro pro User/Monat (mind. 2) with their main inclusions, landline calls "ab 0,84 ct" and outgoing calls "ab 0,5 ct/min", free number porting, no set-up fee, a one-month term cancellable with one working day's notice to month end, and all prices plus VAT — enough for a rough budget. But I cannot compute our real annual bill: I found no published price for numbers, devices, contact centre seats, the Teams integration, group statistics, or the extra extensions and SIM cards from the third onward, and enterprise is quote-only. 3 5 8 24
The IT Administrator
The three business plans are public at 12,95 Euro, 17,95 Euro and 22,95 Euro per user per month with a two-user minimum and their main inclusions, alongside no set-up fee, a one-month term cancellable with one working day's notice, free number porting, prices excluding VAT, and named add-on prices for the call recorder at 3 ct./min. and web SMS at 9,9 ct. The captured pages give different figures for API costs — the help pages state the price as free for sipgate products while the service description mentions a monthly base fee plus a fee per API call — and I found no public information on what numbers cost, on contact centre seats, the Microsoft Teams add-on or devices. 5 8 12 24
The Contact Centre Lead
Three business plans are published at 12.95, 17.95 and 22.95 Euro per user and month with a two-user minimum, including a German flat rate in business L and an EU flat rate in business XL, with no setup fee, a one-month term cancellable with one working day's notice to month end, and all prices stated plus VAT. The call recorder at 3 ct./min., web SMS at 9,9 ct. and free number porting are priced. We found no public price for the optional contact centre, the Microsoft Teams add-on, individual numbers or devices, so I cannot compute a full annual cost for my eighteen agents from the captured pages alone. 5 8 16 24
The Inside Sales Lead
All three business plans are public — 12.95, 17.95 and 22.95 Euro per user per month from two users — with no set-up fee, a one-month term and one working day's notice, VAT treatment stated, porting free, and add-ons priced such as the call recorder at 3 ct./min and Web-SMS at 9.9 ct. We found no public information on the price of numbers, devices, the contact centre or the AI features, and Enterprise is by quote. 5 8 24
The Data Protection Officer
The three business plans are public — 12.95, 17.95 and 22.95 Euro per user and month, minimum two users — with their main inclusions listed, alongside a Call Recorder at 3 ct./min., Web-SMS at 9.9 ct., free number porting, no set-up fee, monthly cancellation with one working day's notice, and all prices excluding VAT. We found no public information on what numbers or devices cost, or on the price of the optional contact centre, the Microsoft Teams integration and the group-statistics add-on, and the Enterprise plan is quote-only, so the true annual cost is not computable from the public pages. 5 8 17 24
The Skeptic
Three business plans are priced per user and month — business S at 12,95 Euro, business L at 17,95 Euro, business XL at 22,95 Euro, minimum two users — with their inclusions, zero setup fee, monthly terms cancellable at one working day's notice to the month's end, VAT treatment stated, porting free, and several add-ons priced: Call Recorder at 3 ct./min., Web-SMS at 9,9 ct., a Zusatzanschluss at 4,95 Euro. The rest of the bill is not computable from public pages: we found no prices for numbers, devices, contact centre seats, the Teams add-on or the API's monthly base fee, per-minute rates appear only as floors such as "ab 0,5 ct/min", and Enterprise is quote-only. 5 8 12 24

Where this could be wrong
- Evidence ages. The oldest capture behind this page is from 5 Nov 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
- Weak sourcing — Legal entity, Hosting location, Data processing agreement. Not confirmed on the vendor’s own pages as captured.
- AI can misread a source. Extraction and judgement are automated; a citation guarantees traceability, not infallibility. If something here is wrong, say so — no account needed, every report is decided within 5 business days, and accepted corrections are published.
