Managing phone numbers in an organization involves assigning, tracking, and reassigning them to users, services, or conferencing bridges. It includes direct inward dialing (DID) and toll-free numbers, which are available from your service provider or Microsoft Teams, and is an important aspect of the MS-700 Managing Microsoft Teams exam.
Assigning Numbers
As an organization, you should only receive phone numbers in Teams Admin Centre or using PowerShell if they’re for your direct users, auto attendants, call queues, conference bridges, or operator connect.
To assign in Teams Admin Centre, navigate to Voice > Direct Routing. From the ‘Available Numbers’ section, assign the number to the user. If PowerShell is your preferred method, use the `Set-CsPhoneNumberAssignment` cmdlet.
Set-CsPhoneNumberAssignment -Identity "
Type TeamsAutoAttendant -PhoneNumberApplicationId "
In this example, <PhoneNumber> is the number you’re assigning, and <autoattendantID> is the ID of the auto attendant to which you’re assigning the number.
Managing Numbers
Managing numbers involves tracking and reassigning. You can see the list of phone numbers in Teams admin center (Teams admin center > Voice > Phone Numbers). Here, you can see whether the number is assigned to a user or service.
Use PowerShell to find information about a specific number using the `Get-CsPhoneNumberAssignment` cmdlet.
Get-CsPhoneNumberAssignment -Identity "
<PhoneNumber> in this example represents the number whose information you’d like to retrieve.
The `Remove-CsPhoneNumberAssignment` cmdlet will allow you to remove an assignment:
Remove-CsPhoneNumberAssignment -TelephoneNumber "
In this case, <PhoneNumber> is the number you’d like to unassign.
Managing Conferencing Bridges
Microsoft Teams allows you to set up conference bridges with dedicated phone numbers. This allows users to dial into the conference bridge from any device, promoting easy collaboration, regardless of an attendees’ location.
To manage these numbers, navigate to the Teams admin center, then to ‘Meetings’ > ‘Conference Bridges’. Here, you’ll see a list of all your dial-in numbers, along with the languages supported by each. A phone number can’t be assigned to a user if it’s assigned to a conference bridge.
Phone number management is an important aspect of the MS-700 exam, highlighting the importance of setup and control over how phone numbers are used. A well-configured system can ensure seamless communication in several languages and differing global locations. Using this knowledge will assist in preparing for the MS-700 Managing Microsoft Teams examination.
