I would like to process the ${billsec} variable in the conf/autoload_configs/cdr_csv.conf.xml file below, returning a different value for the INSERT command. I already have written a lua function which takes an integer value from ${billsec} and returns a string. It is stored in freeswitch/scripts as sec2time.lua. Do I change the sql template below to ., ${lua(billsec)}, .? <configuration name="cdr_csv.conf" description="CDR CSV Format"> <settings> <param name="default-template" value="sql"/> <param name="rotate-on-hup" value="true"/> <param name="legs" value="a"/> </settings> <templates> <template name="sql">INSERT INTO cdr VALUES ("${caller_id_name}","${caller_id_number}","${destination_number}","${contex t}" ,"${start_stamp}","${answer_stamp}","${end_stamp}","${duration}","${billsec} ",... </templates> </configuration> Thanks, Lars
