Set up Communications Credits for your organization

Communication credits can only be purchased web-direct (on, but here is the trick if you are a CSP customer.

Applies to:Skype for Business, Microsoft Teams

You will need to set up Communications Credits if you would like to use toll-free numbers with Skype for Business and Microsoft Teams. Also, we recommend that you set up Communications Credits for your Calling Plans (Domestic or International) and Audio Conferencing users who need the ability to dial out to any destination. Many countries/regions are included, but some destinations may not be included in your Calling Plan or Audio Conferencing subscriptions. If you don't set up Communications Credits billing and assign a Communications Credits license to your users and you run out minutes for your organization (depending on your Calling Plan or Audio Conferencing plan in your country/region), those users won't be able to make calls or dial out from Audio Conferencing meetings. You can get more information, including recommended funding amounts, by reading What are Communications Credits?


To find out how much it costs, see the rates here.

Step 1: Assign an Audio Conferencing or Calling Plan license to your users

When you sign up, you get a certain number of minutes depending on your country/region. For US-based customers check here. After you use those minutes, calls will be disconnected. To prevent this from happening, you need to set up Communications Credits.

To do so, you need to assign an Audio Conferencing or Phone System license to your users.

  • Assign an Audio Conferencing license to your users.

  • Assign Phone System and a domestic or domestic and international Calling Plan license to your users. 


    Although it's not required for Communications Credits, you still need to also assign a Domestic Calling Plan or an Domestic and International Calling Plan license.

    After you assign these licenses, you will need to get your phone numbers for your organization, and then assign those numbers to the people in your organization. 

Step 2: Set up Communications Credits for your organization

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

  2. In the left navigation of the Microsoft 365 admin center, go to Billing > Subscriptions > Add subscriptions.

  3. Expand Add-on subscriptions, and then choose Communications Credits > Buy now.

    If you do not see the Communication credit subscription listed. Select either one of these offers
    If you are a Commercial/Corp/EDU or nonprofits customer

    If you are a GCC customer 
  4. On the Communications Credits subscription page, fill in your information, and then click Next:

    • Add funds Enter the amount that you want to add to your account. If you don't enable auto-recharge, once these funds are depleted, calling capabilities that are enabled using Communications Credits will be disrupted (such as inbound toll-free service). To avoid having to manually replenish your Communications Credits balance each time your balance reaches 0 (zero), we recommend you enable the auto-recharge feature.

    • Auto-recharge Enabling auto-recharge will automatically refill your account when the balance falls below the threshold that you set.

      It's recommended that you use the Auto-recharge setting to avoid any disruption of service should your Communications Credits balance reach 0 (zero). You will be sent an email when recharge transactions succeed, when recharge transactions fail (such as an expired credit card), and when your Communications Credits balance reaches 0 (zero).

    • Recharge amount Enter the amount in the Recharge with box that you want added to your account once it reaches the trigger amount below.

    • Trigger amount Enter the amount in When the balance falls below box that will be used to ' trigger ' the auto-recharge. Once your balance falls below this amount, the recharge amount will be added automatically to your account.


      Funds will be applied only to Communications Credits at Microsoft published rates when the services are used. Any funds not used within 12 months of the purchase date will expire and be forfeited.

      Monthly billing for Communication Credits will only be applied if the alloted fund has been used, to learn how to check your monthly usage, read Skype for Business PSTN usage report

  5. Enter your payment information and click Place order.

    Each organization will have a different usage of Calling Plan volume and rates to consider. You will need to get this type of usage data from your current service provider. Organizations already using Skype for Business Online already as their service provider can get usage data by reviewing it in the Skype for Business admin center > Reports > PSTN usage details report.

When you are setting up Communications Credits, you will need to investigate call usage for your organization to determine the amounts you need. You can get call usage information by reviewing the PSTN usage details report. This report lets you export the call data records to Excel if you need to store the data or create custom reports. To learn how to see usage, read Skype for Business PSTN usage report.
