sipgate flow

What it does

Done-for-you service

NoYou build and operate the voicebot yourself; sipgate supplies only the telephony and audio layer under the API.Bauen Sie Ihren individuellen Voicebot einfach selbst und bringen Sie ihn mit Flow ans Telefon. Ihre Logik, unsere Telefonie, sofort einsatzbereit.sipgate.de/flow ↗

How much it does unattended

Runs autonomously

YesYour application handles a whole live call unattended, answering with speak, transfer or hangup actions per event; a human only enters if you transfer.You receive events (session start, user speech, DTMF) over HTTP webhooks or WebSocket and respond with actions (speak, play audio, transfer, hang up).flow.sipgate.io/faq.html ↗

Multi-agent

PartlyOne flow owns a call; coordination between agents happens by transferring the call with context passing rather than by any orchestration framework.SSML für Feintuning, Weiterleitungen mit Context-Passing, Warm Handover geht alles über simple JSON-Befehle.sipgate.de/flow ↗

Agent permissions

PartlyIn-call actions are open, but the powerful ones (outbound dialling, SMS sending, voice-to-voice mode) stay locked until sipgate support reviews the account.send_sms is only available upon request and after a positive review by sipgate support (fraud / scam protection).flow.sipgate.io/api/actions/send-sms.ht… ↗

Which models it runs on

Claude

YesClaude is used through your own backend: sipgate flow carries audio and transcripts, and the docs treat Anthropic Claude as a supported LLM to stream from.When integrating Large Language Models (LLMs) like OpenAI's GPT, Anthropic's Claude, or similar services with sipgate flow, how you stream responses…flow.sipgate.io/api/guides/streaming-ll… ↗

GPT

YesSame path as Claude: OpenAI GPT is named as an LLM you stream from your own service, with sipgate flow handling speech both ways.When integrating Large Language Models (LLMs) like OpenAI's GPT, Anthropic's Claude, or similar services with sipgate flow, how you stream responses…flow.sipgate.io/api/guides/streaming-ll… ↗

Open models

YesThe LLM is entirely yours, so an open-weight model works; the vendor publishes no list of supported models because it never runs one for you.Your application owns the conversation logic and can call any LLM you choose.flow.sipgate.io/faq.html ↗

Model choice

YesYou pick the LLM outright; sipgate only chooses among its own STT and TTS providers, which you also select per session or per action.It handles the telephony, speech-to-text, and text-to-speech, so you keep full control over your conversation logic and your choice of LLMflow.sipgate.io/faq.html ↗

Where you use it

On the command line

NoThe docs enumerate every integration path (HTTP webhook, WebSocket, TypeScript SDK) and none of them is a terminal tool.HTTP webhooks for serverless, WebSocket for real-time, or use our TypeScript SDK for convenience.flow.sipgate.io ↗

In a browser

PartlyA hosted web surface exists only for configuration, meaning webhook settings and shared secrets in the sipgate account, not for talking to the agent.When configuring your webhook settings, you can optionally store a shared secret if you want to use Flow authenticationflow.sipgate.io/api/authentication.html ↗

Whose machine it runs on

Self-hosted

NoThe telephony and speech layer runs only on sipgate's own German infrastructure; you host your webhook, never the service itself.sipgate flow runs on EU infrastructure operated by sipgate in Germany, is ISO 27001-certified, and is built to meet GDPR and EU AI Act requirementsflow.sipgate.io/faq.html ↗

Open source

PartlyOnly the client is open: the first-party TypeScript SDK is published under Apache-2.0, while the voice and telephony service behind it is closed and hosted.License: Apache-2.0npmjs.com/package/@sipgate/ai-flow-sdk ↗

What it costs to run

How it meters

YesBilling is per talk minute: four prepaid minute packages, each with a published per-extra-minute rate and no base fee, cancellable monthly.Small 2.500 Minuten 249,95 € 9,9 ctsipgate.de/flow ↗

Free tier

NoThe published package table is a closed list of four paid tiers starting at 249,95 €; no free or trial Flow tier appears anywhere on it.Paket Inkludierte Minuten Paketpreis Jede weitere Minute in EUR Small 2.500 Minuten 249,95 € 9,9 ctsipgate.de/flow ↗

API access

YesThe product is the API: plain JSON events and actions over HTTP webhooks or WebSocket, with no SDK required and examples in several languages.The API uses plain JSON over HTTP webhooks or WebSocket, with examples in Python, Node.js, Go, and Ruby.flow.sipgate.io/faq.html ↗

Bring your own key

PartlyYou bring your own LLM and its keys, but the STT and TTS providers are sipgate-side selections, and there is no bring-your-own-cloud option.Your application owns the conversation logic and can call any LLM you choose.flow.sipgate.io/faq.html ↗

Buying it for a team

A company can buy it

YesSold business-to-business by a German telco, with minute packages priced net of VAT and an explicitly multi-tenant offer for resellers.Sie wollen Ihren Kunden Voice-Funktionen anbieten? Flow ist der richtige Telefoniepartner dafür. Multi-Tenant-fähig, skalierbar und ganz einfach…sipgate.de/flow ↗

Seat model

NoThere are no seats and no per-user floor: the rate card meters talk minutes only, with no base fee and monthly cancellation.ohne Grundgebühr • minutengenaue Abrechnung • monatlich kündbarsipgate.de/flow ↗

Pooled budget

YesOne account-level minute allowance covers every call and every flow; minutes are billed to the second, with overage at the package's published rate.Medium 10.000 Minuten 899,95 € 8,9 ctsipgate.de/flow ↗

Admin controls

PartlyThe sipgate account separates admin from restricted users, which governs configuration rights, not a policy engine limiting what the agent may do mid-call.Die sipgate Dienste ermöglichen es, eingerichtete Benutzer:innen zwischen Admin-Usern mit weitreichenden Rechten und normalen Usern mit…sipgate.de/sicherheit-datenschutz ↗

Single sign-on

PartlyCustomers who already run an SSO provider can enforce SSO login for all their users; Google and Apple sign-in is open to everyone, and neither SAML nor OIDC is named.Kund:innen, die einen SSO-Anbieter nutzen, können die SSO-basierte Anmeldung für alle ihre User einrichten.sipgate.de/sicherheit-datenschutz ↗

What happens to your code

Opt out of training

PartlyUnder AI Security sipgate states model training on customer data is contractually excluded and processing stays in Europe, but the sentence covers its own ChatGPT usage, not Flow's speech subprocessors specifically.Eine weitere Nutzung der Daten, zum Beispiel für Machine Learning durch OpenAI, ist vertraglich ausgeschlossen.sipgate.de/sicherheit-datenschutz ↗

Data residency

YesGermany: infrastructure sits in ISO 27001 data centres in Frankfurt and Düsseldorf, and ElevenLabs voices were moved onto the EU endpoint by default.Unsere zuverlässigen Rechenzentren, die nach ISO 27001 zertifiziert sind, befinden sich an den Standorten Frankfurt und Düsseldorf.sipgate.de/flow ↗

Getting out

PartlyDeletion is documented and self-service under the data-processing agreement, but no data-export path is published and nothing states whether unused package minutes roll over.Werden Daten im Auftrag der Kund:innen gespeichert, greifen die Regelungen des Vertrags zur Verarbeitung von Daten im Auftrag. In diesen Fällen…sipgate.de/sicherheit-datenschutz ↗

Certifications

PartlyISO 27001 certification of the data centres plus GDPR and EU AI Act alignment are claimed; SOC 2 is claimed nowhere on the site.sipgate flow runs on EU infrastructure operated by sipgate in Germany, is ISO 27001-certified, and is built to meet GDPR and EU AI Act requirementsflow.sipgate.io/faq.html ↗
