Note
For information about disabling tool-free numbers for Teams users, see Disabling toll-free numbers for specific Teams users.
If your organization has toll-free numbers in its Microsoft Audio Conferencing Bridge, you can allow or prevent their usage in the meetings of specific organizers.
By default, all users in your organization are enabled for using toll-free numbers, meaning that those numbers, if available, can be used by participants to join their meetings. If this isn't the desired behavior for some users in your organization, you can restrict specific users from using those numbers in their meetings via a toll-free number enablement control.
When toll-free numbers are disabled for a given organizer:
A toll-free number won't be included in their meeting invites.
Toll-free numbers won't be listed on the "Find a local number" page that is referenced in the participants meeting invites.
Participants won't be able to join the meeting of the given organizer if they dial any toll-free number of the organization.
All meetings of the organizer will be automatically rescheduled, and the toll-free number will be removed from them.
Important
This will resend all of the email invites of the organizer to all the participants of those meetings.
Participants can continue joining meetings of the organizer using toll numbers.

From the Microsoft Teams admin center:
In the left navigation, select Users, and then select the user from the list of available users.
