Carrier CDR Download

Download CarrierX Call Data Records via the api.

The application requires NodeJS to run.

Installation

In the terminal, change directory to the project root and run:

NPM

cd nodejs
npm install

Yarn

cd nodejs
yarn install

Running

In the project root directory, run the following

node cxGetCdrs.js <latest | range> <options> outputFileName.csv

Commands - latest & range

There are two commands available: latest & range. latest gets records since the last time it was run and stores the SID of the last downloaded record. range gets records in some date range.

Command latest

The latest command tells the downloader to get the records since the last time it was called. This mode is intended to be run on a regular basis (e.g. daily), so it keeps track of the last record received and picks up where it left off. By default, it will use ./state.json to store SIDs, but you can specify the file to use.

Short	Long	Required	Description
-t	--token	Required	Security access token available via the API or in the portal. Documentation
-s	--state-file	Optional	The file where the app should store the SIDs (record identifiers) for the last record downloaded. Default - ./state.json
-b <date>	--begin <date>	Required	The begining date (and optionally time), inclusive, in ISO 8601 format - YYYY-MM-DD[T[HH:[MM:[SS][Z]]]]. Dates and times are UTC. Examples: 2025-11-01, 2025-11-01T10:00:00Z
-e <date>	--end <date>	Optional	The end date (and optionally time), exclusive, in ISO 8601 format - YYYY-MM-DD[THH:MM:SS]. Dates and times are UTC. Default - now.
-f <format>	--format <format>	Optional	The output format, csv or json. Default - csv
-o	--overwrite	Optional	Overwrite the output file. By default the app will not overwrite the output file.
-y	--type	Optional	The type of records to get. Choices: call, conference, message. Default - call
-h	--help	Optional	Display command help

File name - Required argument

You most specify an output file name where records will be written. The app will create the output file but it will not create any directories.

Command range

The range command downloads records in the specified date range. If an end date isn't supplied, all records since begin are downloaded.

NOTE State is not saved with the range command. If you use the range command, a subsequent latest command will not pick up after the last range record downloaded.

Short	Long	Required	Description
-t	--token	Required	Security access token available via the API or in the portal. Documentation
-b <date>	--begin <date>	Required	The begining date (and optionally time), inclusive, in ISO 8601 format - YYYY-MM-DD[T[HH:[MM:[SS][Z]]]]. Dates and times are UTC. Examples: 2025-11-01, 2025-11-01T10:00:00Z
-e <date>	--end <date>	Optional	The end date (and optionally time), exclusive, in ISO 8601 format - YYYY-MM-DD[THH:MM:SS]. Dates and times are UTC. Default - now.
-f <format>	--format <format>	Optional	The output format, csv or json. Default - csv
-o	--overwrite	Optional	Overwrite the output file. By default the app will not overwrite the output file.
-y	--type	Optional	The type of records to get. Choices: call, conference, message. Default - call
-h	--help	Optional	Display command help

File name - Required argument

Examples

NOTE Use caution entering an access token on the command line as commands, and therefore tokens, can be saved in command history files. All examples below use an environment variable $CX_TOKEN where the token is stored.

Get all CDRs

node cxGetCdrs.js latest --token $CX_TOKEN path_to/cdrs.csv

CAUTION The first time this is run, it has the potential to create a very large file. It may be useful to specify a recent beginning date if you don't need the entire history of CDRs.

Since some date

node cxGetCdrs.js latest --token $CX_TOKEN --begin 2024-10-31 path_to/cdrs.csv

or

node cxGetCdrs.js range --token $CX_TOKEN --begin 2024-10-31 path_to/cdrs.csv

The only difference is that using command range, the state won't be save - the last record SID isn't stored.

Date range

node cxGetCdrs.js range --token $CX_TOKEN --begin 2024-10-31 --end 2024-11-06 path_to/cdrs.csv

The end is exclusive, so only records before end are included.

Time range - 1 hour

node cxGetCdrs.js --token $CX_TOKEN --begin 2024-10-31T18:00:00 --end 2024-10-31T19:00:00 path_to/cdrs.csv

As JSON

node cxGetCdrs.js latest --token $CX_TOKEN --format json path_to/cdrs.json

Overwrite output

By default, the app will not overwrite an existing file. If you want to overwrite the file, you need to specify -o or --overwrite.

node cxGetCdrs.js latest --token $CX_TOKEN --overwrite path_to/cdrs.csv

Conference records

If you want conference records instead of SIP call records, specify -y conference or --type conference.

node cxGetCdrs.js latest --token --type conference path_to/cdrs.csv

Message Delivery records

If you want message delivery records instead of SIP call records, specify -y message or --type message.

node cxGetCdrs.js latest --token --type conference path_to/cdrs.csv
