Can you explain this one?
From the Wikipedia article linked by SCV:
Quote:When calling from abroad the initial 0 is not required, and so the E.123 format is recommended, e.g. +44 20 7222 1234 for a London number, +44 118 946 0555 for a Reading number, +44 151 496 0555 for a Liverpool number, +44 1223 345678 for a Cambridge number, and +44 7700 900555 for a mobile telephone number. UK numbers shown with a zero immediately after the country code, either with or without parentheses, are incorrectly formatted.
It is saying that +44 (0) 20 7222 1234 is incorrect. So how do you show a number in both national and international format without having to put it twice? Or is there no way round it but to list it in both formats, eg:
(020) 7222 1234 or +44 20 7222 1234
