10.13.1. Feature Description 
The last incoming and outgoing calls are logged for terminals with
display. The user can query the stored information and use the entries
to establish outgoing connections.
The Call Log Database is sized to support maximum 30 call log entries per subscriber.
However,
with the release of OpenScape V11R1, this capacity has been significantly increased,
supporting up to 70 call log entries per subscriber.
In the part of the call log reserved for outgoing calls, the last 10 called users
are
entered (increased to 20 from OpenScape V11R1); in the part for incoming calls, the
last 20
calling (increased to 50 from OpenScape V11R1) users are stored.
The entries are sorted starting from the newest and ending with the oldest
entry.
The following data is stored for every entry:
- station number max. 22 digits
- station number in E164 number format max. 22 digits (used for CSTA call log from OpenScape 4000 V11R1).
- name (if available) max. 30 characters
- date / time
- Info: free / busy / call state
- call duration (used by CSTA call log from OS4K V11R1).
