Overview
Brook dials your numbers the same way a customer would — a real phone call over the public network. That means it works with virtually any carrier or platform that can receive a call. There's no SDK to install and no change to your agent's code.
Common providers
Teams run Brook against numbers from providers like these:
How a check connects
- You add a phone number and a test suite in the dashboard or via the API.
- On your schedule, Brook places a real outbound call to that number from a regional line.
- Our agent speaks your test questions, listens to the response, and scores the result.
- You get a verdict, latency, and transcript — and an alert if anything failed.
SIP & bring-your-own-carrier
Prefer to keep calls on your own network? Point Brook at a SIP endpoint and we'll dial over your trunk instead of the PSTN. This keeps test traffic inside your carrier relationship and is the path most enterprises choose.
Regions & dialing
Brook dials from numbers in North America, Europe, and APAC, so checks originate close to your callers and reflect real-world routing. Multi-region dialing is available on the Scale tier for teams running agents across several markets.
