Assign a third-party as the dial-in conferencing provider

A dial-in conferencing provider supplies the conference bridge. The conference bridge provides the dial-in phone number, PINs, and conference IDs for meetings that are created. You only need to assign a dial-in conferencing provider to people who are going to schedule or lead Skype for Business meetings.

Dial-in conferencing providers are also called audio-conferencing providers.

Steps to do BEFORE you can assign a third-party dial-in conferencing provider

  1. Depending on your Office 365 plan, you might need to buy PSTN conferencing add-on licenses for the people in your organization who are going to schedule or lead meetings that use dial-in conferencing. To learn more, see Skype for Business add-on licensing.

  2. If you purchased PSTN conferencing add-on licenses, assign them to the people in your organization who are going to schedule or lead meetings that use dial-in conferencing. See Assign Skype for Business licenses.

    Note: If you assign a Skype for Business PSTN Conferencing license to someone AFTER you assign them a third-party dial-in conferencing provider, that person will automatically be set to use Microsoft as their dial-in conferencing provider instead! If this happens, you will need to first remove Microsoft as the dial-in conferencing provider before you can assign a third-party dial-in conferencing provider to them.

  3. Find a third-party dial-in conferencing provider at Microsoft PinPoint. Contact them and find out how to get things set up with them.

    They will give you:

    • Dial-in numbers and toll-free numbers if they are available.

    • Conference IDs that are used for each person who schedules meetings. Some ACPs call these conference passcodes.

      Tip: When you enable a person for dial-in conferencing, and add assign them an third-party dial-in conferencing provider, the dial-in numbers and conference IDs (passcodes) are automatically added to any new Skype for Business Online meetings that they create.

How to assign a third-party dial-in conferencing provider to many people at the same time

  1. In the Skype for Business admin center, choose Dial-in conferencing > Third-party provider > Export wizard, and then follow the steps in the Export Users wizard. When you finish, you’ll have a file that lists the people you want to set up for dial-in conferencing.

  2. Send the file you created to your third-party dial-in conferencing provider. They will add dial-in conferencing information for the people listed in the file, and then return the file to you.

  3. Double-check that the returned file has the right information in it. We've heard of instances where not everyone listed in the file got the right information.

  4. In the Skype for Business admin center, choose Dial-in conferencing > Provider > Import wizard, and then follow the steps in the Import Users wizard.

  5. Send each person the PIN you received from the dial-in conferencing provider. The PIN may be required to call in as the conference call organizer, or leader.

    Note: When you use a third-party dial-in conferencing provider, there isn't a way for you to see or set PINs on behalf of meeting organizers.

When to use a third-party dial-in conferencing provider

If you are in a country where Microsoft dial-in conferencing isn’t available, the service quality isn’t great because of it's location, or you have an existing contract with a third-party dial-in conferencing provider, we recommend using a third-party dial-in conferencing provider. Otherwise, we recommend using Microsoft as your dial-in conferencing provider.

What else do I need to know?

A person in your organization can only use one dial-in conferencing provider. To change a person's dial-in conferencing provider to Microsoft, see Changing a user from a third-party ACP to Microsoft as the dial-in conferencing provider or Assign Microsoft as the dial-in conferencing provider.
