This menu is accessed by pressing the 
HISTORY key. The call log you see is a call log stored on the telephone system. If you log in at another phone that also stores a call log, your call history moves with you.
Your call history contains your most recent answered calls, the most recent calls you made and the most recent missed calls. If configured by the system administrator, it can also include the most recent calls missed by each hunt group of which you are a member.

Missed Calls
Missed calls are calls to you that you did not answer. Your system administrator can also configure whether or not the log includes calls presented to you but are answered by someone else or by voicemail.
The History button is illuminated when you have any new missed calls in your call log. The lamp is extinguished when you have viewed the missed call in the call log or the record of that call is no longer in your call log.
The 
or 
icon is also shown at the top left of the phone display to indicate missed calls and is prefixed with the number of missed calls.
Missed Group Calls
If you are a member of any hunt groups, the system administrator can configure whether your missed calls log should also include missed hunt groups calls. The hunt group does not necessarily have to have rung at your phone. It will be recorded as missed if it was presented to the hunt group and not answered by any of the members including you.
Notes
1.Centralized call log can be turned off by the system administrator. In that case the call log is stored by the phone and is lost if the phone is reset. This guide only covers the centralized call log stored by the telephone system.
2.The call log on other types of phones is a local call log maintained by that phone. It will not move with you when you hot desk and it will be lost if the phone is restarted.
3.The redial function uses the outgoing call records stored in the call log.
