CallRail handles call tracking, lead qualification and appointment booking for businesses of all sizes. The records it holds — calls, texts and forms — sit under its own export limits, retention rules and terms governing what you may do with your own information. Most of what a firm runs was never designed to hand its data back. Milemarker's ingestion layer connects to CallRail and lands what your agreements permit into a Snowflake environment your firm owns and administers, normalized into a model that stays stable even when the systems around it change. That means CallRail stops being a corner of the business nobody can report on. Its data joins your custodial, CRM, billing and planning sources under one set of rules — row-level entitlements, PII masking and SOC 2 Type II controls you set, rather than the scope any one vendor happens to offer.
