Hi team, I am trying to get these values from the lua script for custom CDR report, I am able to get few values but many variables are missing or getting null value. Any help would be appreciated. local aa=session:getVariable("context"); local bb=session:getVariable("destination_number"); local cc=session:getVariable("caller_id_name"); local dd=session:getVariable("caller_id_number"); local ee=session:getVariable("network_addr"); local ff=session:getVariable("ani"); local ii=session:getVariable("source"); local jj=session:getVariable("chan_name"); local kk=session:getVariable("uuid"); local ll=session:getVariable("created_time"); local aa1=session:getVariable("direction"); local bb1=session:getVariable("username"); local cc1=session:getVariable("dialplan"); local dd1=session:getVariable("caller_id_number"); local ee1=session:getVariable("unique_id"); session:execute("bridge","user/601"); session:hangup(); local ff1=session:getVariable("answered_time"); local hh1=session:getVariable("created_time"); local gg1=session:getVariable("hangup_time"); local gg2=session:getVariable("end_stamp"); I am getting values for all the above variables except end_stamp, hangup_time, duration, billsec,hangup_cause. Thanks for your time. Thanks, Bala
