Regex - Delete up to second whitespace
===

I think what i'm trying to do is possible... but I haven't found an answer that achieves  that yet.
I would like to format a string which will be similar to this in javascript:

`+44 (0) 234-567-8901`

The proceeding international ( +44 ) and local ( (0) ) calling code are subject to change, so the string could be longer or shorter. However the format is always the same.

I would like to take this string and remove all characters including whitespaces up to the second whitespace and remove dashes.
e.g:

`+44 (0) 234-567-8901 becomes 2345678901`

Can anyone help?

Thanks
