I am validating a web page via a javascript function using regular expressions. Here is my variable:

var RE_phone = /^[\d\+]{3,4}([\- ]?)\d{1,3}([\- ]?)\d{3}([\- ]?)\d{4}$/;

I am needing it to validate both national and international numbers. So far it is working correctly, except for national numbers.

Here is an example of a national number that I would like to be able to accept as a valid number: 04 4784897 or 044784897.

Can I please have some help to modify my regular expression variable to accept national phone numbers in the above format?

thanks
