Disabling toll-free numbers for specific Skype for Business Online users
Skype for Business Online will be retired on July 31, 2021. If you haven't upgraded your Skype for Business Online users to Microsoft Teams before that date, they will will be automatically scheduled for an assisted upgrade. If you want to upgrade your organization to Teams yourself, we strongly recommend that you begin planning your upgrade path today. Remember that a successful upgrade aligns technical and user readiness, so be sure to leverage our upgrade guidance as you navigate your journey to Teams.
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 is not 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 will no longer be included in his or her meeting invites.
Toll-free numbers will no longer be listed on the "Find a local number" page that is referenced in his or her 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.
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.
Disabling toll-free numbers for specific users
From the Microsoft Teams admin center:
In the left navigation, click Users, and then select the user from the list of available users.
Next to Audio Conferencing, click Edit.
Set Include toll-free numbers in meeting requests from this user to Off.
We are frequently updating how you can manage features found in Skype for Business Online, so the steps here might be a little different.
You can use the AllowTollFreeDialIn parameter of the Set-CsOnlineDialInConferencingUser cmdlet to enable or disable this control. For example:
- Set-CsOnlineDialInConferencingUser email@example.com – AllowTollFreeDialIn $false
