Countries, Calling Codes, and Time Zones
The table below contains the list of countries for which adjustment of calling hours to the local time zone of the destination number is currently supported. For each country, the table specifies its calling code and the time zone which will be used for adjustment. You can get more detailed information about each time zone, including the current UTC and UTC DST offsets, from Wikipedia.
Note that for all countries on this list, except the USA, Canada, Brazil, Mexico, Russia, Indonesia, and Australia, there is a one-to-one correspondence between the country calling code and the time zone that will be used to adjust the calling hours. If a country has territory in multiple time zones (e.g., Portugal), the most populous time zone is selected for conversion.
If a number in the calling list begins with a calling code other than one of the codes specified in this table, it will only be dialed if the campaign calling hours for the corresponding phone type are set to 24/7 and the Comply with State calling hours checkbox is not selected. For more information, see section Calling Hours.
Note: Toll-free area codes of the North American Dialing Plan (800, 844, 855, 866, 877, and 888) are associated with the America/New_York time zone.
