Compare dial-in conferencing providers

When you set up dial-in or PSTN conferencing for Skype for Business, you need to choose a dial-in conferencing provider. You can choose either Microsoft as your dial-in conferencing provider, or a third party.

Whether Microsoft is the dial-in conferencing provider, or a third-party providers this service, in both cases they will do the following:

  • Provide a dial-in conferencing bridge. The conferencing bridge will set dial-in phone numbers, PINs and conference IDs for meetings.

  • Give toll, toll-free and international phone numbers that users will dial into. The phone numbers are then included in the meeting invite.

  • Set the language that users will hear when they dial into a meeting.

  • Create meeting conference IDs that are used when users are joining a meeting.

  • Give you organizer PINs to start meetings over the phone.

Use the following table to compare what you get if you choose Microsoft or a third-party dial-in conferencing provider.
