What is the data type of the field?
Which spaces do you want to remove (left, right, middle)?
Can you give us an example of current data and the expected results?

You can use the REPLACE function:
SELECT REPLACE(PhoneNumberFieldName, ' ', '')

SELECT LEFT(REPLACE(PhoneNumberFieldName, ' ', ''), 20) --and truncate to 20 "numbers"

Q: Do you need/want to check for specifically "numbers" in the column?  Do you want to strip all non-numerics?
