Detailed Review
Revox is narrow on purpose. It only makes outbound calls: cold calls, instant callbacks to inbound leads, reactivating dormant CRM contacts, qualification, booking and post-sale check-ins.
The privacy notice names Daigest SAS, 14 avenue du Général de Gaulle, Saint-Mandé, as the operator.
Pricing per prospect
Instead of a per-minute meter, the Starter plan sells 200 prospects a month for EUR 100 excluding VAT. Each extra prospect worked costs EUR 0.50, and a prospect gets up to five call attempts and a pick-up if they call back.
Setup, configuration and onboarding are included, and the first month carries no commitment. Unused credits roll into the next month.
Driven from an AI assistant
An MCP connector lets Claude, ChatGPT, Claude Code or Codex create voice assistants, choose voices, place calls and read each call's outcome and transcript.
The site also has recorded sample calls by sector, which makes it easy to judge voice quality before booking.
Data handling
Revox says data is hosted in France and Europe, siloed per customer account, never sold and never used to train models, with retention set by the customer.
Limitations to Consider
Revox does outbound calls only, so inbound reception needs another tool such as fonio or sipgate sona. A prospect-based price can cost more than per-minute billing for long conversations. The company is young and the site gives no certification list; we could not verify the exact hosting provider.
Who Should Use Revox
Outbound sales and recruiting teams that want a fixed price per lead worked and a quick start.
