CDR Overview

What are CDRs (Call Detail Record)? 

CDR is the data produced during phone calls. It contains all the call attributes such as the call time, its duration, the hangup time and cause and much more. CDR have two main interests: their analysis can provide insightful data, especially at scale and they are essential to diagnostic and debug a faulty telephone system.

CDRs offer a vast amount of call metrics, including: calling and called number, type of number, caller country and region if possible, precise timeline of the call (time of call initialization, answered and hang up), who hang up, total duration of the call, its price, precise timeline of the key(s) pressed, etc.

We distinguish between inbound CDR and outbound CDR that offer slightly different information.

Where to access the CDRs?
