How to dial a phone number in Vientiane Lao?

From outside Lao, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 856 (the country code for Lao), then 21 the 2-3 digit area code of the place you're calling (Vientiane) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Lao must use the leading '0' and the area phone code, even when calling locally.
