What is Call Detail Reporting?
Call Detail Reporting (also known as Call Accounting) captures granular, timestamped details of every call—across PSTN, queues, and internal interactions. It enables organizations to:
Audit and analyze calling activity
Allocate costs accurately by department or user
Meet compliance and retention mandates
Optimize usage and adoption across your Teams deployment
This CDR capability complements ISI’s Queue Analytics, providing full-spectrum visibility into all voice flows—not just queue-related interactions.
Why CDR Matters for Microsoft Teams
Native Microsoft Teams Reporting (Out-of-the-Box Limitations)
-
Teams Admin Center offers PSTN usage reports (e.g. Calling Plans, Direct Routing with SIP flow), allowing 7–45 day queries, export to Excel, and basic insights
-
Call Quality Dashboard (CQD) provides deeper analytics but is complex to set up and primarily focused on quality metrics—not full CDR-level detail
-
PowerBI—too complex, hard to setup and manage, not business user friendly
How ISI’s CDR Elevates Teams Reporting
ISI overcomes these limitations by delivering:
-
Unlimited data retention—preserve historical call records indefinitely for compliance, audit, and trend analysis
-
Extended data fields—access 50+ detailed CDR fields (versus ~8 in native reports), enabling deeper insights into callers, call flows, auto-attendants, queues, PSTN types, and more
-
Platform-wide integration—consolidate reporting across Teams, Webex Calling, Avaya, and other UC systems in one unified UI
-
Advanced governance—granular role-based access, audit trails, APIs, and full Azure-cloud security compliance (SOC, HIPAA, etc.)
