To log an error from a signaling process in the Blueworx Voice Response error log, use the CA_Log_Error() subroutine or the CA_Log_Event() subroutine. To log an system event or a private event, use the CA_Log_Event() subroutine, which allows you to write to the same files as the LogEvent state table action. (Refer to the Application Development using State Tables information for details.)
