Humans & AI
You decide where the AI stands
Every call on Callr is one of two kinds: a real conversation between two humans with AI working quietly behind it — or a call your AI agent answers itself.
Two humans talk — the AI never joins
The conversation stays exactly what it has always been: your customer and your team, no bot in between. In the background, AI transcribes, summarizes, and extracts the data that matters, then pushes it to your CRM and BI tools.
- Invisible to both callers — nothing changes on the line
- Transcripts, summaries, sentiment, and structured data
- Pushed automatically to your CRM and BI tools
No one picks up? The AI answers
After hours, on overflow, or by design: an AI voice agent takes the call — first-hand or instead of voicemail — resolves what it can, and hands the rest to your team with full context.
- Answers first-hand or replaces voicemail
- Qualifies, books, and resolves end to end
- Hands off to a human with full context
Voice AI
Bring your own AI model.
- Plug GPT, Claude, Mistral, Llama, or your in-house stack.
- Extract insights such as customer sentiment, intent, satisfaction, and more.
- Automatically enrich your CRM.

Data sovereignty
You choose the law that governs your data.
Callr runs two companies — TCLR SAS in France and The Callr Corp in the United States. When you sign up, you decide which one holds your contract and which law applies: EU law or US law. Most providers force one regime on you; we let you choose — something no competitor offers.
TCLR SAS
France
Your contract is held by TCLR SAS in France and governed by EU and French law, with full GDPR. Your data stays under European jurisdiction — outside the reach of the US CLOUD Act and FISA 702.
- Data controller and contract in the EU
- Full GDPR · French & EU courts
- Outside the US CLOUD Act & FISA 702
The Callr Corp
United States
Your contract is held by The Callr Corp in the United States and governed by US law — the familiar choice for American businesses that need stateside contracting, billing and compliance.
- US entity, US-law contract
- Stateside billing & compliance
- Terms US enterprises already know
Our servers, our data centers
Callr operates its own hardware in owned and colocated facilities. We don’t rent compute from a hyperscaler, so your data doesn’t sit on infrastructure controlled by a third party.
Choose your geography
Pin your numbers and data to France, the United States, or Singapore. One platform, three regions — you decide where data physically lives for residency, latency and compliance.
Same platform, either way
The APIs, numbers and features are identical whichever jurisdiction you pick. Your legal choice never costs you product or performance.
A genuine EU option
Because Callr owns its French infrastructure through TCLR SAS, the EU-law path is the real thing — your data on Callr-owned servers in France, under EU jurisdiction, not a US provider’s European region.

As of June 2026, based on each provider’s public terms, DPA and infrastructure pages. “US-law exposure” reflects whether a US parent or affiliate, or US-controlled cloud, could place customer data within reach of the US CLOUD Act / FISA 702 — an EU-law contract alone does not remove it. Classifications can change; verify before relying on this for compliance decisions.
