You have a Microsoft Teams Phone deployment. You need to configure users to include a toll free phone number as part of their meeting invites. Which type of policy should you configure?

Voice routing policies control how outbound PSTN calls are routed through calling plans or direct routing; they do not control meeting invite phone numbers.

The Audio Conferencing policy in Teams admin center allows administrators to configure the dial-in phone numbers that appear in meeting invitations, including the ability to assign a toll-free number as the default or supplemental number for users. This policy directly governs the conferencing bridge numbers surfaced in meeting invites. No other policy type controls the phone numbers embedded in Teams meeting invite content.

Customization policies govern Teams client branding elements; they do not configure conferencing dial-in numbers.

Meeting policies control meeting features such as recording, chat, and participant permissions, not the conferencing phone numbers in invites.
