Query to delete EXTERNAL duplicated calls: 
NOTE:  change SXXX into your site code (ie. SIT1) and 'yyyy-mm-dd 00:00:00' and 'yyyy-mm-dd 00:00:00' with your date range

WITH temp AS (
    SELECT 
        c.[lPKId],
        ROW_NUMBER() OVER (
            PARTITION BY 
                c.[dData],
                c.[dOra],
                c.[dDurata],
                c.[sSito],
                c.[sDerivato],
                c.[sNumero]
            ORDER BY 
                c.[lPKId]
        ) AS rowNumber
    FROM [dbo].[Chiamate] c
    WHERE c.[sSito] = 'SXXX'
      AND c.[dData] BETWEEN 'yyyy-mm-dd 00:00:00' AND 'yyyy-mm-dd 00:00:00'
)
DELETE FROM [BibCalls]
WHERE [Id] IN (
    SELECT [lPKId] 
    FROM temp
    WHERE rowNumber > 1
);
