To the best of my knowledge, CDR output does not have agent in/out info. It is Call Detail Recording only, meaning it will have 1 record for each call you make/receive.
In this record, you will get the info for the calling party, and the receiving party. IE: you will know which agent made the call/ received the call, the call duration, etc, but you will not know when agents logged in/out.
CDR formats can be configured but if you want the field names and reference, go look in Definity ECS Administrator Guide 555-233-506 (this is for version 8.2), page 1228
Otherwise, you can hook your system up to your PC serial port and use hyperterm to capture some output. This is what I did to make my program that takes CDR data and dumpt to an SQL database.
