Regular expression to split number

I am splitting the phone number entered into two parts using regular expressions below

(^\d{3}) - last 7 digits

\d{7}\b - first 3 digits

This works fine if entered value is 1234567890 or 123-456-7890

and fails if value entered is 123 456 7890 (with spaces) or 123.456.7890

how to modify above expressions to trim (spaces and .)?

Thanks

Need a regular expression

I have a required field validator for a texbox, but I just found out that the texbox can have a space in it (for a delimiter, let's say).

I checked the .net and regexlib.com, but couldn't find what I was looking for.

I simply need a regular expression that basically excepts any character string including spaces in it or even a space by itself.

Can someone help me out?
