Why each option

Toll-free audio conferencing numbers in Microsoft Teams require Communication Credits to be funded; when credits are depleted, toll-free numbers stop working while standard toll numbers continue to function.

AAdd the toll-free number to an Audio Conferencing policy.

Adding a toll-free number to an Audio Conferencing policy controls assignment but does not resolve a service outage caused by depleted credit balance.

BSet Anonymous users and dial-in callers can start a meeting to On.

The 'Anonymous users and dial-in callers can start a meeting' setting controls meeting entry permissions and is unrelated to toll-free number billing or availability.

CAdd Communication Credits.Correct

Communication Credits act as a pay-as-you-go balance that funds toll-free audio conferencing minutes in Microsoft Teams. Toll-free calls are charged against this balance because the organization, not the caller, bears the cost. When the Communication Credits balance reaches zero, toll-free bridge numbers immediately stop accepting calls, which explains why local toll numbers - where the caller pays - continue working. Adding Communication Credits restores toll-free number functionality.

DSet the toll-free number as the default conference bridge.

Setting the toll-free number as the default conference bridge changes which number appears in meeting invites but does not restore functionality of a number that is down due to missing credits.
