Changing a user from a third-party conferencing provider to Microsoft as the dial-in conferencing provider

Skype for Business dial-in conferencing enables users in your organization to create a Skype for Business Online meeting which users can dial into using a phone. In Office 365, you have the option of using a Microsoft dial-in conferencing bridge or a third-party dial-in conferencing bridge that is hosted by an approved audio conferencing provider (ACP).

After you have enabled a user or users for dial-in conferencing, you can change the dial-in conferencing provider for a single user to either Microsoft or third-party provider. When you select multiple users, and they both use Microsoft as the dial-in conferencing provider, you can only change the default dial-in number for those users or disable dial-in conferencing for them. You can also reset their conference IDs and PINs.

To use dial-in conferencing using Microsoft as the dial-in conferencing provider you must purchase and assign licenses to your users. See, Skype for Business Online licensing overview.

Tip: You can't change the dial-in conferencing provider to a third-party ACP for multiple users.

Moving a user from an ACP to Microsoft as the dial-in conferencing provider

  1. Sign in to Office 365 with your work or school account.

  2. Purchase and assign an Enterprise E1, Enterprise E3, or Enterprise E5 license to your users. To learn how to assign licenses, see Assign or unassign licenses for Office 365 for business.

    Important: You can use the Skype for Business Online Standalone Plan 2 instead of an E1, E3, or E5 license but you can't use Skype for Business Online Standalone Plan 3.

    To learn more about which licenses you need to buy, see Skype for Business Online licensing overview.

  3. Purchase and assign the licenses to your users. To learn which licenses you need to buy, see Skype for Business add-on licensing.

    If you are using an:

    • Enterprise E5 license: PSTN Conferencing is included! You don't need to buy an add-on license.

    • Enterprise E1 or Enterprise E3 license: Buy the PSTN Conferencing add-on license and assign the license to your users.

    Tip: If you are using an Enterprise E5 license without PSTN conferencing, you can still use a third-party audio conferencing provider (ACP) for dial-in conferencing.

  4. Then go to the Office 365 admin center > Skype for Business.

  5. In the Skype for Business admin center, in the left navigation go to Users> and then select the user or users you want to change the dial-in conferencing provider for.

  6. In the Action pane, click Edit.

  7. In the Skype for Business admin center, in the left navigation go to Dial-in conferencing > Provider name drop-down, and then select Microsoft in the drop-down as the dial-in conferencing provider for the user.

    Note: After you assign a Skype for Business PSTN Conferencing license, Microsoft might not appear in the drop-down as a dial-in conferencing provider. If this happens, either log out of the Office 365 admin center or press CTRL+F5 to refresh the browser window.

  8. Click Save.

What else should I know?

  • After you enable the user for dial-in conferencing their name will appear in the Skype for Business admin center > Dial-in conferencing > Dial-in users list.

  • If you select the user in the list, you can view the default dial-in conferencing information of the user but you won't be able to see the dial-in conferencing PIN. You can reset the dial-in conferencing PIN of a user by clicking Reset.

  • If you want to change dial-in conferencing settings for a user, you can select the user from the list and then click Edit and make your changes on the Properties page.
