Discover the correct PowerShell cmdlet to configure default toll-free Audio Conferencing numbers for specific Microsoft Teams users. Learn how Set-CsOnlineDialInConferencingUser ensures precise user-level updates.

Question

You have a Microsoft Teams deployment that has offices in New York and Seattle.

You acquire a new toll-free Audio Conferencing number for the Seattle office.

You plan to use PowerShell to set the new number as the default Audio Conferencing number for the users in the Seattle office.

Which PowerShell cmdlet should you run?

Select only one answer.

A. Set-CsOnlineDialInConferencingBridge
B. Set-CsOnlineDialInConferencingServiceNumber
C. Set-CsOnlineDialInConferencingUser
D. Set-CsOnlineDialInConferencingUserDefaultNumber

Answer

To configure a new toll-free Audio Conferencing number for users in the Seattle office, use the Set-CsOnlineDialInConferencingUser cmdlet.

C. Set-CsOnlineDialInConferencingUser

Explanation

Audio Conferencing enables users in your company to create Teams meetings, and then allow users to dial in to those meetings using a phone number.

A conferencing bridge gives you a set of dial-in phone numbers for your company.

Use the Set-CsOnlineDialInConferencingUser cmdlet to modify the properties of a user that is enabled for the Microsoft Audio Conferencing service.

Purpose of the Cmdlet

  • Set-CsOnlineDialInConferencingUser modifies user-level audio conferencing settings, including assigning toll or toll-free numbers.
  • Use the -TollFreeServiceNumber parameter to set the default toll-free number for individual users.

Deprecated Alternatives

Set-CsOnlineDialInConferencingUserDefaultNumber (Option D) is deprecated as of July 2024. Microsoft recommends using Teams audio conferencing policies or Set-CsOnlineDialInConferencingUser instead.

Why Other Options Are Incorrect

  • Set-CsOnlineDialInConferencingBridge (Option A): Configures bridge-level settings (e.g., default service number for an entire bridge), not user-specific assignments.
  • Set-CsOnlineDialInConferencingServiceNumber: Invalid cmdlet; not listed in official documentation.

Example Command

To assign the toll-free number to Seattle users:

Set-CsOnlineDialInConferencingUser -Identity "[email protected]" -TollFreeServiceNumber +18005551234

Additional Notes

  • Bulk Updates: For multiple users, automate with scripts iterating through Seattle-based accounts.
  • Policy Overrides: Toll-free numbers in TeamsAudioConferencingPolicy take precedence over user-level settings.

By using Option C, you ensure compliance with current Microsoft recommendations and precise user-level configuration.
