Setting up Fully Automatic DNS Provisioning

Automatic provisioning of DNS records and derived trunk domain fully automates the onboarding process for a new Microsoft direct routing tenant. The wizard adds the new domain on the end customer M365 tenant:

■ Creates a PSTN gateway and domain
■ Creates a TXT record in the Service Provider Azure DNS environment
■ Adds A-Record to the Service Provider DNS environment
■ Creates a temporary activation user in the end customer tenant with the newly created domain assigned and licensed with a Microsoft Office 365 Phone System user license.
● The following Administrative roles must be assigned to the Customer administrator (see Grant Roles to Global admin Account):
✔ Domain Name Administrator (for txt and A-record creation)
✔ User Administrator (for user license activation of the PSTN trunk)

The automatic provisioning of the DNS sub domains requires the following setup on Service Provider Azure tenant:

■ Registering DNS Application (Service Provider Tenant)
■ Creating A Records for SBC Devices
■ Assign Access Control
■ Configure DNS API

Once the above setup has been completed, the Onboarding wizard can be used to provision the DNS sub domains (see Fully Automatic DNS Provisioning).
