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?
On SENDR, you can access an overview of the campaign reports directly from the interface. If you need more details, you can download the full report of the campaign, a table including the CDR built on top of the address book you used.
On CALLTRACKR.io can be accessed in the CDR submenu. You can view them straight on the web interface or you can download them in a .csv format.
With our API
We offer four different methods to fetch CDRs, that are all detailed in the documentation:
- The cdr.get_by_callid_in method (doc) and cdr.get_by_callid_out method (doc) fetch all CDR for a given caller ID.
- Finally, the cdr.export_async method (doc) pushes information about the availability of the CDRs (.csv file) to a webhook.
You can get a synthesis (daily or weekly) of your CDRs delivered by mail. Contact our support to set it up.
