You will need to set up Communications Credits if you would like to use toll-free numbers Microsoft Voice. Also, we recommend that you set up Communications Credits for your Calling Plans (Domestic, International, Teams with calling plan, etc) 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?
