Help with exporting data using BCP

Hi,
I am trying to use BCP to export data from a table into multiple CSV files based on the telephone number. I run the query in QA and what I get back is:

usage: BCP {dbtable | query} {in | out | queryout | format} datafile
  [-m maxerrors]            [-f formatfile]          [-e errfile]
  [-F firstrow]             [-L lastrow]             [-b batchsize]
  [-n native type]          [-c character type]      [-w wide character type]
  [-N keep non-text native] [-V file format version] [-q quoted identifier]
  [-C code page specifier]  [-t field terminator]    [-r row terminator]
  [-i inputfile]            [-o outfile]             [-a packetsize]
  [-S server name]          [-U username]            [-P password]
  [-T trusted connection]   [-v version]             [-R regional enable]
  [-k keep null values]     [-E keep identity values]
  [-h "load hints"]
NULL

In the grid view and (12 row(s) affected) x 212 in the messages view. There are 212 distinct telephone numbers so the loop is working correctly if I use PRINT i get

BCP "select Call_Orig from Abrient..[0800] where Call_Orig='08009705582' queryout "Number_08009705582.CSV"  -c -S ***.***.*.** -U **** -P **********

And that all looks ok, but it's not producing any files, I have added myself to sysadmin, I have also ran directly on the server machine, I have also tried several variations of the code below but with no success.
******************************************************************************************
DECLARE @CallOrigID  VARCHAR(11)
DECLARE @BCPString  VARCHAR(8000)


DECLARE cCallOrig CURSOR FOR
SELECT DISTINCT Call_Orig
FROM [0800]


OPEN cCallOrig

FETCH NEXT FROM cCallOrig
INTO @CallOrigID

WHILE @@FETCH_STATUS = 0
BEGIN
  SET @BCPString = 'BCP "'
  SET @BCPString = @BCPString + 'select Call_Orig from Abrient..[0800] where Call_Orig=''' + @CallOrigID + ''''
  SET @BCPString = @BCPString + ' queryout '
  SET @BCPString = @BCPString + '"C:\OutputData\Number_' + @CallOrigID + '.CSV" '
  SET @BCPString = @BCPString + ' -c -S ***.***.**.*** -U **** -P *********'




exec master.dbo.xp_cmdshell @BCPString

  FETCH NEXT FROM cCallOrig
  INTO @CallOrigID
END

CLOSE cCallOrig
DEALLOCATE cCallOrig

If anybody could help me with this that would be great.
