FreeSWITCH generating http-json CDRs


  • FreeSWITCH with vanilla configuration adding mod_json_cdr for CDR generation.
  • Modified following users (with configs in etc/freeswitch/directory/default): 1001-prepaid, 1002-postpaid, 1003-pseudoprepaid, 1004-rated, 1006-prepaid, 1007-rated.
  • Have added inside default dialplan CGR own extensions just before routing towards users (etc/freeswitch/dialplan/default.xml).
  • FreeSWITCH configured to generate default http-json CDRs.
  • CGRateS with following components:
  • CGR-SM started as prepaid controller, with debits taking place at 5s intervals.
  • CGR-CDRS component receiving raw CDRs from FreeSWITCH, storing them and attaching costs inside CGR StorDB.
  • CGR-CDRE exporting processed CDRs from CGR StorDB (export path: /tmp).
  • CGR-History component keeping the archive of the rates modifications (path browsable with git client at /tmp/cgr_history).

Starting FreeSWITCH with custom configuration

/usr/share/cgrates/tutorials/fs_evsock/freeswitch/etc/init.d/freeswitch start

To verify that FreeSWITCH is running we run the console command:

fs_cli -x status

Starting CGRateS with custom configuration

/usr/share/cgrates/tutorials/fs_evsock/cgrates/etc/init.d/cgrates start

Check that cgrates is running

cgr-console status

CDR processing

At the end of each call FreeSWITCH will issue a http post with the CDR. This will reach inside CGRateS through the CDRS component (close to real-time). Once in-there it will be instantly rated and it is ready to be exported:

cgr-console 'cdrs_export CdrFormat="csv" ExportDir="/tmp"'

CGRateS Usage

Since it is common to most of the tutorials, the example for CGRateS usage is provided in a separate page here
