Ever picked a doctor from your insurer’s website, called, and heard “he retired” or “we don’t take that plan”? Insurers have to re-check every listing every 90 days. Rollcall makes those calls, fixes the list, and keeps the receptionist’s own words behind every change.

Each answer is one tool call with the office’s own words attached. A write gate in code, not in the prompt, decides what reaches the directory.

Every simulated office has a hidden truth sheet. After the sweep, every value the agent wrote is compared with it. Three of the forty calls were re-recorded after the bug they exposed was fixed in code; the other thirty-seven are first takes.
