Hi, @vanama3 

You need to sort the table and add an index column in PQ like:

Then  try calculated column like:

Index1 = RANKX(FILTER(ALL('Table'),'Table'[phone number]=EARLIER('Table'[phone number])),'Table'[Index],,ASC,Dense)

Result =
VAR _mindate =
    CALCULATE (
        MAX ( 'Table'[Date] ),
        FILTER ( ALLEXCEPT ( 'Table', 'Table'[phone number] ), 'Table'[Index1] = 1 )
    )
VAR _datediff =
    DATEDIFF ( _mindate, 'Table'[Date], DAY )
RETURN
    SWITCH (
        TRUE (),
        'Table'[Index1] = 1, BLANK (),
        _datediff = 0, "Called on same day",
        _datediff = 1, "Called on next day",
        "Called after " & _datediff & " days"
    )
