calculate row wise total sum
you have to put your query in CTE for it you have to use  ROLLUP

;WITH CTE AS
(
-- Your Query
)


then 

SELECT
  RowLabels = ISNULL(RowLabels, 'Grand Total'),
  FacetoFace = SUM(FacetoFace),
  Phone = SUM(Phone),
  GrandTotal = SUM(GrandTotal)
FROM CTE
GROUP BY ROLLUP(RowLabels);


SAMPLE DEMO

declare @temp table (RowLabels nvarchar(max), FacetoFace int, Phone int, GrandTotal int)

insert into @temp values ('Craig Irwin  ',73,6  ,79)
insert into @temp values ('Holly Murphy ',27,124,151)
insert into @temp values ('Julie Brown  ',37,28 ,65)
insert into @temp values ('Kevin Borth  ',52,35 ,87)
insert into @temp values ('Linda Krueger',46,23 ,69)
insert into @temp values ('Robert Bell  ',66,21 ,87)


SELECT
  RowLabels = ISNULL(RowLabels, 'Grand Total'),
  FacetoFace = SUM(FacetoFace),
  Phone = SUM(Phone),
  GrandTotal = SUM(GrandTotal)
FROM @temp
GROUP BY ROLLUP(RowLabels);
