Explanation

A Survivable Branch Appliance (SBA) provides limited PSTN calling capability to a branch site when WAN connectivity to Microsoft's cloud is lost. The SBA acts as a local proxy/registrar specifically for Microsoft Teams desktop clients. Windows desktop Teams clients (D) can register to the SBA and place or receive basic PSTN calls during an outage. Call queues (A) and Audio Conferencing (B) are cloud-dependent services that require live connectivity to Microsoft 365 and cannot function through an SBA. Teams panels (C) are room scheduling displays, not voice endpoints, and are not supported by SBA for PSTN continuity.
