You set specific geo-permissions for each of your sub-accounts. This helps you have custom geo-permissions settings for each of your sub-accounts. For example, you can enable calls to specific countries when using a specific sub-account and disable the same countries when using a different sub-account. You can also reset the sub-account geo-permissions to the default setting.
Step 1: Navigate to the Voice Geo Permissions page and select the sub-account from the Account menu dropdown.
Step 2: After selecting the sub-account, click on Remove override to set default preferences.
