To set up PSTN (Public Switched Telephone Network)

Step 1: Buy and assign a Teams Phone license

• Ensure each user has a Teams Phone license. You can assign these licenses via the Teams admin center
• For licensing considerations, see Teams Phone licensing.

Step 2: Choose a PSTN connectivity option

Microsoft options for making external calls to the PSTN include:

• Microsoft Calling Plan. An all-in-the-cloud solution with Microsoft as your PSTN carrier. If you choose Microsoft Calling Plan as your connectivity option, you have a choice of Calling Plan options, including Domestic, International, and Pay-as-you-go plans.
• Operator Connect. If your existing carrier participates in the Microsoft Operator Connect program, they can manage PSTN calling for you.
• Teams Phone Mobile. If your existing carrier participates in the Microsoft Teams Phone Mobile program, they can manage the service for using SIM-enabled mobile phone numbers with Teams.
• Direct Routing. This option lets you use your own PSTN carrier by connecting your SBCs to Teams Phone.

Step 3: Get and assign phone numbers for your users and services

Obtain phone numbers for your users through the Teams admin center, port existing numbers, or request new numbers

• In Teams Admin Center -> Voice ->Phone Numbers
• Assign a number to the user

Step 4: Set up emergency calling

To set up emergency calling, you--or your PSTN carrier--must define emergency locations and ensure that emergency locations are assigned to each user.

You can complete the full setup steps based on the needs and conditions of your organization.

Finally, I also want to provide some Microsoft articles that you can prefer during your setting up

Hope my information will be helpful for you. Wishing you a week full of energy and good health!
