10.13.2. Feature Characteristics 
- The feature can only be used with optiPoint 410/420 and OpenStage 10/15/20/30/40,
DPIP35 and
CP1xx, CP2xx terminals.
- There are two different ways to log incoming calls, depending on
the station:
- Logging of all incoming calls regardless of whether a connection was
established or not. => ALL
- Logging of the unsuccessful connection attempts. => TRIES
- Calls are also logged during a temporary failure of the terminal as unsuccessful
call attempts.
- The dialed destination number is logged, even if a different destination
was reached due to call forwarding.
- Outgoing calls established by using number redial, direct call or
repertory key are not stored in the outgoing calls log.
- If a call is signalled on several stations, e.g. group call, RNA,
HG, the call is logged in the call log of all called stations.
- CHESE
- A call is only logged in a CHESE caller list if it not answered by a
member of the CHESE, in other words calls for the executive, which are
picked up by the secretary, are not logged in the executive's caller
list. And vice versa.
- If one CHESE member deletes an entry in the caller list (by calling
the original party back or manually deleting this entry), the entry is
also deleted for the other CHESE member.
- 2 or more executives are assigned to one secretary: When one caller
calls all executives one after the other, every executive gets an entry
in its call-log of not-answered calls. The secretary gets all calls but
only the last call is stored in its call-log (update of time of call
of the older entry in case of calls from the same caller). After answering/deleting
the last call, the call-logs of the other executives is not updated.
- A key can be assigned to query the call log. The LED is on when there
are new incoming calls.
- A "delete entire log" function (separate menu option) can be set
up.
- A function can be set up so that the called party instead of the
transferring party is stored in the call log (originating number).
- If Autoset Relocate is set, the call log is also moved.
- The call log can only be read on the home station.
- The call log cannot be modified or stored using administration and
maintenance.
- The call log is protected against unauthorized readout by the Chapter
107, "Data Security at the Terminal" feature.
- The call log contents are retained after hard and soft restarts.
- Call log has only been implemented for voice services.
