Introduction

The "4. Call Duration Grouped by Time" report from the "CDR" report group allows you to identify how calls are distributed by duration ranges, to understand patterns of very short or very long calls and relate them to consumption (minutes) and cost. It is useful for operational control, validation of campaign/management behavior, and general monitoring of telephone spending.

Report Information

• interval: Classifies calls into predefined duration ranges: 0-5 sec (calls lasting between 0 and 5 seconds), 6-20 sec (between 6 and 20 seconds), 21-60 sec (between 21 and 60 seconds), 61-120 sec (between 61 and 120 seconds), and 121-> sec (calls lasting 121 seconds or more); these ranges help you detect concentrations of calls that are too short (possible failed attempts, quick hang-ups, or validations) or too long (complex management, high handling times, or transfers).
• calls: Indicates the number of calls that fall within each duration interval; useful for sizing the volume of interactions per range and, for example, confirming whether a high percentage of "short" calls is expected behavior or an alert.
• minutes: Shows the total minutes consumed by calls in each interval; this field allows you to see which intervals generate the highest total consumption, as an interval with few calls can concentrate many minutes if they are long calls.
• cost: Represents the total cost associated with calls in each interval; it is key for financial/FinOps telephone control, as it allows you to identify which duration ranges are "driving" spending and prioritize actions (dialing adjustments, routing, scripts, schedules, or controls).
• percentage: Expresses the percentage share of each interval relative to the total (according to the report's calculation); helps you quickly compare the relative weight of each range and monitor changes in the pattern (e.g., increase in calls >121s or growth in 0-5s calls) between periods.
