Tolled dial-in conferencing and domestic dial-out conferencing services are both included in the PSTN Conferencing service plan. Each user is assigned a PSTN Conferencing number based on where that user has been assigned a licensing location as an Office 365 user. A participant can dial out to other participants as a domestic call based on the country of that dial-out location. The user will have a link to around 60 dial-in numbers from countries across the globe, which can be used by participants in those countries to join the call without international charges.

Although there are no distinct service limits associated with tolled dial-in and domestic dial-out conferencing, Microsoft monitors the service for fraud or abuse and reserves the right to limit use in cases where the service quality might be compromised.

Between December 1, 2015 and September 1, 2016, there is an introductory offer period during which international dial-out capabilities are available to customers in all PSTN Conferencing sell-to countries. These customers can use international dial-out conferencing to any tolled number residing in any one of the PSTN Conferencing sell-to countries.

Enabling PSTN Consumption allows users to dial in to conferences toll free, and conference organizers can dial out internationally after September 1, 2016. Check rates for toll free dial-in and for international dial-out.

Companies with users located in various countries around the world can purchase PSTN services in a sell-to country (for example, the United States) and then provision their users anywhere in the world with those licenses where Microsoft offers dial-in conferencing numbers.
