Hi,
From CUCM command line run:
run sql select enduser.userid,device.name,datetimestamp from extensionmobilitydynamic inner join enduser on extensionmobilitydynamic.fkenduser_lastlogin=enduser.pkid inner join device on extensionmobilitydynamic.fkdevice=device.pkid where device.name = 'SEPXXXXXX' where SEPXXXXX is the device name of the IP Phone you want to check.
