A call log provides a list of the last 100 calls on the phone. The call log list is sorted by the timestamps, with the latest call at the top of the list. Each entry in the call log has the following information:

• Call type icon

• Caller name

• Caller number

• Call time-stamp

• Call duration

You must enable the call log option for your extension to record the call entries. If you enable the summarize call logs option, you can view the aggregate of calls for each day. The phone sums up the calls for each call type from a caller and lists them in the Recents screen.

If you do not want the phone to log the Call forward or Call forward-Busy as a missed call, contact your administrator to make the required settings. If the primary extension user has logged out of the phone, the phone logs the forwarded-all call or forwarded-busy call as a missed call.

Missed call reason

For missed calls, the phone additionally displays the reason for the missed call that the call server provides. If you have an Offline call log enabled on your phone, the phone loses the call forwarding status in the missed call reason. Avaya J100 Series IP Phones display the following reasons for missing the call if any of the following features are active on your phone:

Avaya J100 Series IP Phones encrypt the content of the call log file from the software version 4.0.3 and later.

If you need to downgrade the phone software to a version earlier than 4.0.3, the phone cannot retain the call log details. Contact your administrator to enable the required settings to retain the call log details.
