Siverti lives inside your phone system and talks to your tools. It is not an IVR or a chatbot — it is an AI voice receptionist that qualifies, books and routes like your best teammate, and never sleeps.
Natural voice
EU-trained models in Spanish, English, Catalan, French and Portuguese. Human cadence, pauses, push-backs.
500–900 ms latency
EU edge inference and synthesis under one second. No awkward pauses.
Real tool calling
Books, emails, opens tickets, fires webhooks. Your business thinks out loud.
EU data residency
GDPR-compliant. Signed DPA. We don't train on your calls. Full stop.
01
Speech recognition on the EU edge (≤ 280 ms). Detects intent, language and context. If you interrupt, it stops.
02
Tool calling against your calendar, CRM, FAQ and inventory. Knows what your business can offer and what it cannot promise.
03
Books in Google Calendar, creates the lead in HubSpot, sends WhatsApp. If needed, transfers to a human with context already summarised.
Anatomy
The call comes in, gets understood, acted on and answered before the customer registers the pause. We measure every turn; we show it raw.

The voice is natural and latency stays under 800 ms. Callers talk to Siverti like they would to a person — if that's your call. You can also introduce it as a virtual assistant; the tone is yours.
Siverti knows its limits by design. When a question falls outside its scope, it hands off to your team with a context summary — or books a callback.
100% in the European Union. GDPR-compliant, signed DPA available, full logical separation per organisation.
Yes. We integrate via SIP, Twilio, Aircall, or use a Siverti-owned number. You activate without changing provider.
A basic agent is live in under 30 minutes via the wizard. For catalog-driven and advanced setups, assisted onboarding is included.
You can let it ring — or let Siverti convert it.
