typography

What is the proper way to typeset a telephone number? The number would be of the format:

Country-local-number-appendix

For example:

+31 6 21123234 5

(If these are the proper english terms…)

I think that in these cases is good to refer to some standards, such as those of the International Telecommunication Union: E.123 : Notation for national and international telephone numbers, e-mail addresses and web addresses. (Section 2 Notation for National and International Telephone Numbers, of the English version).
