Data center and dial-in regions relationship

When customizing the data center regions, the web portal will display a warning notification if there’s a conflict with the dial-in countries.

For example, if you deselect Australia as a data center region, you will not be able to select Australia or New Zealand as a dial-in country. In additional, you will not be able to select Australia or New Zealand toll or toll-free/fee-based toll numbers.

Notes:

• To see the associated data center of specific dial-in numbers, select the toll or toll-free/fee-based toll numbers and view the Data Center column.
• Call-out countries/regions are not affected by the account's selected data centers. The only exception is China. You must have the China data center selected to see China as a call-out country.

The following table shows the relationship between the two settings. It explains the limitations to the dial-in countries based on the select data center region.
