whether they were outgoing, incoming, or missed calls.
If the caller is listed in your Contacts, your phone displays the

If the caller is not listed in your Contacts, your phone only
displays the number and the date and time when the call
occurred.
Note: If you return a call from the voicemail menu, it will not be
included in your phone's Outgoing Calls list.
