Audio Conferencing common questions

The following are some of the top questions we get from our customers who want to use Audio Conferencing.

For step-by-step instructions for setting up Audio Conferencing, see Set up Audio Conferencing for Skype for Business and Microsoft Teams.

What are the benefits of Audio Conferencing?

Calling in to meetings is very useful when people are on the road, for example, and can't attend a meeting using the Skype for Business or Microsoft Teams app on their laptop or mobile devices. But there are other scenarios in which using a phone to attend a Skype for Business or Microsoft Teams meeting can be a better option than using an app on a computer:

  • Internet connectivity is limited.

  • A meeting is audio only.

  • The person tried to join a Skype for Business meeting and it failed.

  • The call quality is better if they dial in.

  • People can join a meeting "hands free" using Bluetooth devices.

  • People find it's easier and more convenient for their situation.

Who can attend an Audio Conferencing meeting? And who can I hear?

Anyone who has the dial-in number and conference ID can join a Skype for Business or Microsoft Teams meeting, unless the meeting organizer has locked the meeting.

Whether you're calling in using a phone or the Skype for Business or Microsoft Teams apps, you'll be able to hear everyone else on the call, and they can hear you. The meeting organizer has the ability to "mute" meeting attendees if they don't want to hear them.

Can I add a toll-free number for my Audio Conferencing users?

Yes, toll-free phone numbers (service numbers) are available but only in some countries/regions. To see a list of the numbers that are available, go here.

How many local dial-in numbers are currently supported?

There are local dial-in numbers that are assigned to you when you purchase the licenses for Audio Conferencing. The dial-in numbers will be included in the meeting invite. These local numbers will be only available to your organization. The phone assigned to your organization and that number is shared by the users within that organization that are enabled for Audio Conferencing. So, Skype for Business or Microsoft Teams meetings scheduled by User A and another User B will both have the same dial-in number.

Local dial-in numbers, and also in some cases international dial-in numbers from the country where your organization is located, will be included on the meeting invite. If a meeting attendee uses a different number that is include in the invite, it will be a shared phone number.

How many international dial-in numbers does Audio Conferencing in Office 365 support?

For a current list of countries/regions, see Phone numbers for Audio Conferencing.

Can I set up local numbers for Audio Conferencing from additional cities in the country?

If phone numbers for Audio Conferencing aren't available in your area or don't meet the needs of your organization, please send us feedback at SkypeFeedback forums.

What is the maximum length of the Audio Conferencing meetings?

The maximum length of time depends on who is in the meeting and the type of authentication they used to join the meeting.

We added a new feature that allows you, the admin, to send and update Audio Conferencing information and PIN in email. To learn more about it, including how to disable it, see Enable or disable sending emails when Audio Conferencing settings change.

Can Audio Conferencing be used by the users who are part of an on-premises deployment of Skype for Business Server 2015?

We're not quite there. However, you can continue to use audio conferencing that is available in Skype for Business Server 2015 along with a PSTN gateway for your on-premise users.

Can a user get a personal conference ID?

Skype for Business and Microsoft Teams users will be randomly assigned conferencing IDs and can't reserve or set a static conference ID that only they can use.

Can I use Audio Conferencing with Skype Meeting Broadcast?

There isn't support currently for users enabled for Audio Conferencing to join a Skype Meeting Broadcast.

Can a user get operator assistance during a meeting?

No, a user can't get any operator assistance or support by pressing *0 during the meeting. If there are issues with Audio Conferencing, an administrator for an organization can contact Microsoft support for Office 365.

How does a user access or change their conference ID?

A Skype for Business or Microsoft Teams user can find the conference ID that is assigned to them by scheduling a meeting in Outlook and Outlook on the web. Also, users can find the conference ID in the email that will be sent to them after they are set up.

Note

Users won't be able to reset their conference ID. The conference ID can only be reset by you, the admin, for the organization.

We are working on a solution that will let the user access and reset a conference ID without help from an organization's admin.

Can attendees dial out to international phone numbers when they are in a Skype for Business or Microsoft Teams meeting?

Yes, attendees can dial out internationally and invite other callers into a Skype for Business or Microsoft Teams meeting. See Dialing out from a meeting so other people can join it.

How does a Skype for Business or Microsoft Teams user schedule a meeting with Audio Conferencing meeting details?

When a user is assigned an Audio Conferencing license and the user creates a new Skype for Business or Microsoft Teams meeting in Outlook or Outlook on the web, the dial-in phone numbers and conferencing IDs are added to the meeting invite automatically.

How does a user schedule and start a meeting when all attendees will be using a phone to dial-in?

When a user is assigned an Audio Conferencing license, the user is assigned what is called a reservation-less conference ID. This conference ID can be shared along with the conference access phone numbers with meeting attendees without the user having to schedule a meeting.

Here is a table illustrating the scenarios when the organizer and all of the attendees dial in to a meeting:
