Verify License Availability

An M365 is license is required for activating the PSTN trunk (Activation user license). When the new customer is added, a unique Live Platform portal URL is created for the customer with their own sub domain name (based on Customer Short Name defined in the Onboarding). This sub domain is configured on the Service Provider’s DNS server. Activation of the sub domain requires an available M365 license which is applied during the Onboarding as part of the Automatic DNS provisioning process (see Register End Customer Tenant DNS Sub domains). The Onboarding creates an Activation user (Ump-Activation-User) for this purpose.

You must verify that at least one of the following licenses is available on the customer M365 tenant:

Microsoft 365 E5 (no Teams)
Microsoft Teams Enterprise
Office 365 E1 / E3 with Microsoft Teams Phone Standard

Microsoft recently realigned its Global licensing for Microsoft 365, Office 365, and Teams for customers in countries residing outside of Europe. As part of these changes, Microsoft is offering a new Microsoft 365 E5 license that does not include Teams. For more information, see the following links:

Teams Licensing
Microsoft Teams add-on licenses
Teams Phone with PSTN connectivity licenses

The license that is assigned to the 'Activation' user for the Fully Automatic DNS Provisioning can be removed from this user once there is at least one other user in the organization who has the same domain as the Customer Sub-domain trunk. Consequently, this license can be reused and the trunk can remain active.

To verify license availability:
1. Open the Microsoft Admin portal with Global permissions (https://admin.microsoft.com.
2. In the Navigation pane, select Billing > Licenses.

3. Verify that there is at least 1 license is available; click the relevant license for details.

4. If all available licenses are already assigned, you need to release a license; in the Navigation pane, select Users > Active Users.

5. Select any existing Domain user, deselect all active licenses for this user and then click Save changes.
