Collaboration Communications Systems Engineer — Question 4

You port phone numbers from a legacy carrier to Microsoft Teams Phone to use with Microsoft Teams Calling Plans.
You attempt to assign a number to a resource account that will be used by an auto attendant, but the number does NOT appear on the list of available numbers.
You need to ensure that you can assign the number to the resource account.
What should you do?

Answer options

• A. Run the Set-CsOnlineApplicationInstance cmdlet.
• B. Submit a request to convert the number from a user number to a service number.
• C. Run the Set-CsTeamsUnassignedNumberTreatiment cmdlet.
• D. Order a new number from Microsoft.

Correct answer: B

Explanation

The correct answer is B because converting the number from a user number to a service number is necessary for it to be assigned to a resource account. Option A is incorrect as it pertains to application settings and does not affect number assignment. Option C is also incorrect because it deals with handling unassigned numbers, not converting them. Option D is not necessary if the existing number can be converted.
