When configuring the Caller List you have the option of setting the length of the Caller and Redial List.
A change in the length of the Caller List also affects the All and Missed lists, as the entries of the Caller List are the basis for these lists. Please note that deletion of a call from the Caller List causes the associated callback request to be deleted too.
To define the length of the lists in the call journal
