Explanation

When phone numbers are ported into Microsoft Teams, they arrive classified as user (subscriber) numbers by default. Auto attendants and call queues can only be assigned service numbers - a different inventory type. Because this classification cannot be changed through the Teams Admin Center UI, you must open a Microsoft support case to request the inventory type conversion before anything else can proceed.

Why the distractors are wrong:

  • B is wrong because the numbers are already ported - creating another port order is redundant and solves nothing.
  • C is wrong because you physically cannot assign a user-type number to a resource account; the system blocks it until the number is reclassified as a service number.
  • D is wrong because acquiring a new toll number defeats the purpose - the goal is to use the specific existing ported number, not obtain a fresh one.

Memory tip: Think of it as a job title change - a number ported in as a "user employee" can't take on an "auto attendant manager" role until HR (Microsoft Support) updates its classification in the system.
