Dial-in phone numbers in a meeting invite

When a Skype for Business Online or Microsoft Teams user schedules a meeting in Outlook or Outlook Web App, the default audio conferencing number that is set for the user is included in the meeting invite. If you want to select a different default number for one or more users, you can change that by going to the Skype for Business admin center > Audio conferencing > Users.

Other dial-in numbers can be seen by clicking on Find a local number link in the meeting invite.

Dial-in phone numbers set on an audio conferencing bridge

There are two types of audio conferencing phone numbers that can be assigned to your conferencing bridge: Shared and Dedicated. Both types of these numbers can be used by any caller to join audio meetings that are being held in your organization.

Dedicated phone numbers are those phone numbers that are only available to users within your organization. You can change the languages that are used when someone calls in to one of these numbers.

Shared phone numbers are those phone numbers that can be shared with other Office 365 organizations. You can't change the languages that are used when someone calls in to one of these numbers.

While the default audio conferencing number that is assigned to an organizer is only included in the meeting invite, a caller can use any of the phone numbers that are assigned to your conferencing bridge to join a meeting. The list of phone numbers that can be used to join a meeting is available using the Find a local number link that is included on every meeting invite.

Automatically assigned audio conferencing phone numbers

Shared audio conferencing phone numbers are automatically assigned to organizations when they're enabled for audio conferencing. When the phone numbers are assigned, a phone number is assigned as the default phone number of the conferencing bridge. The phone number assigned as the default number of the bridge will be one from the country/region of the organization.

Note

The country or region location of your organization can be found by signing in to the Office 365 admin center and looking under Organization Profile.

Caution

Due to limited availability of toll phone numbers in Venezuela, Indonesia, and United Arab Emirates (UAE), organizations from these countries/regions won't have an Audio Conferencing toll number automatically assigned to them. Toll-free numbers from these locations are available depending on available inventory.

Dedicated audio conferencing phone numbers are service numbers that you can get and then assign to your organization. Service numbers can be found by using the Skype for Business admin center. For details, see Getting service phone numbers for Skype for Business and Microsoft Teams.
