You can modify the presence box to do something else, like setting a queue member on pause. That gets logged into queue_log and you can extract reports with asternic call center stats.
You can also turn on the audit log in fop2 passing the -a command line option at startup, you can edit /etc/sysconfig/fop2 and change the OPTIONS to be something like
OPTIONS="-d -a /var/log/fop2_audit.log"
You can then parse the fop2_audit.log to see actions performed within fop2.
