Try http://rubular.com/r/b6K0LOcn3N Any better regular expression ???
Explanation to my RegEx: ?(\d|\+)(\+|\d|\(|\)|-| |\.){7,25} ?

1. start catching no. when a space or not a space is detected only.
2. start matching if first is 0-9 or + match any character in (+|\d|(|)|-| |.)
3. 7,25 because mini length of phone no. is 7 and
4. max around 25 including whitespaces and - etc

Answer 1

Try using some word boundaries \b:

(?:\b\d|\+)(?:\+|\d|\(|\)|-| |\.){7,25}\b

And I turned the capture groups into non-capturing groups. If you only need the whole number, I don't think that you need capture groups.

\b matches when there is a 'word' character followed by a 'non-word' character or vice versa (i.e. either \w\W or \W\w).
