Yeah. Apologies for contributing to the noise, but since someone mentioned it earlier...
I had a suspicion it might be standard somewhere.
The ITU recommendation is E.123 (02/01), ITU article number E20897 in English. That document recommends that a hyphen, space or period be used to provide visual separation between groups of numbers; parentheses are to be used for sections of the number which are sometimes not dialled, but not in the full international notation which includes an E.164 country-code.
E.123 also tells us how to write our e-mail addresses and URLs on business cards, except that it calls URLs "web addresses". At least, this is what I can glean from the many E.123 summaries I could find, since the actual document isn't available for free download. We're certainly lucky to have the ITU.
