The user call log shown by one-X Portal for IP Office is stored on the telephone system as part of the user's settings. Up to 30 records are stored, with new records replacing the old ones when the limit is reached. However, for repeated call to or from the same number, the existing record is updated and the number of calls count increased.
For incoming call, by default, only personal calls (non hunt group) to the user that were answered by the user or which went unanswered anywhere are included in the call log.
Calls that the user does not answer but are answered by voicemail or another extension are not normally logged as missed calls. To enable the logging of missed calls, the system-wide setting Log Missed Calls Answered at Coverage (System | Telephony | Call Log) should be enabled in the IP Office telephone system configuration.
•Missed Hunt Group Calls
By default, only hunt group calls that the user answers are logged. To enable the logging of missed hunt group calls, the system-wide setting Log Missed Huntgroup Calls should also be enabled in the IP Office telephone system configuration. The user must also be configured in the telephone systems with the hunt groups for which their call log can include missed calls (User | Telephony | Call Log).
Old call records are automatically deleted when the call log capacity is reached and a new call record needs to be added. In addition, through the telephone system configuration you can configure the telephone system to delete log entries after a set period. Select Delete entries after (User | Telephony | Call Log).
For users using 1400, 1600, 9500 or 9600 Series phone with a Call Log or History button, or an M-Series or T-Series phone, by default the same call log as shown by the portal is also shown on the phone. You can then use and edit the call log from the phone or from one-X Portal for IP Office. The two change in parallel.
Users, using any other type of phone that has a call log, that call log is stored by the phone itself and so does not necessarily match the call log shown in one-X Portal for IP Office. For example, calls made using the one-X Portal for IP Office do not appear in the phone's call log and vice versa.
In either case, the one-X call log is limited to displaying 255 records.
