RoundRobin Dial OS places high-volume parallel outbound calls to opted-in leads and instantly routes every live, human-answered call to an available agent. Dial volume is a computed value — the minimum of human capacity, campaign ceilings, answer-probability budget, routing capacity, abandonment budget, provider limits, and compliance gating — never a raw admin input. Managers get a live sales-floor control tower and admins a command center for teams, campaigns, numbers, compliance, and analytics. It is compliance-aware by design with consent tracking, opt-out management, call-window rules, and audit trails.
