search and replace on blank removing leading 0's

I've a column of data in excel which should represent telephone numbers -for some reason the data input technician has added random spaces between 'segments' of the number. Currently that column is formatted as text for whatever reason. If I search and replace to replace a space with no space, it deletes all the numbers leading 0 therefore destroying the data. Is there anyway past this, to remove the leading, mid section or trailing spaces, but the process not deleting the leading 0's which is how the vast majority of numbers are?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You could use the SUBSTITUTE formula.

=SUBSTITUTE(A2, " ", "")

That will remove all the spaces and keep the leading zeroes.
