For policy-based compliance recording with Direct Routing, the SBC must be configured to invite the recording solution. To enable this, the Teams infrastructure needs to be aware that call history and other details should be forwarded to the gateway. The -ForwardCallHistory parameter on the Set-CsOnlinePstnGateway cmdlet enables this behavior, allowing the SBC to receive the necessary information to fork the media stream to the recording bot.

Device configuration profiles in the Teams admin center are the primary method for managing settings on Teams Rooms on Android. This is where you can set an admin password, configure custom backgrounds for branding, and manage device-level settings.

Meeting acceptance behavior is controlled by the calendar processing settings of the resource account's mailbox associated with the Teams Room. Configuring AutomateProcessing to AutoAccept in Exchange Online PowerShell or the equivalent GUI setting is required for automatic meeting acceptance.

Teams meeting templates are designed for this exact purpose. They allow administrators to pre-configure a set of meeting options (like lobby bypass, chat availability, and who can record) that can be applied when scheduling specific types of meetings, such as virtual appointments. This approach allows for strict controls on external-facing meetings without impacting the flexibility of internal collaboration meetings.

A single auto attendant can be configured with different call flows for business hours and after-hours. Within the auto attendant settings, you define your business hours, and then you can specify a distinct set of actions or greetings for calls that arrive outside of that schedule. There is no need for a separate auto attendant or resource account.

The Set-CsTenantNetworkConfiguration cmdlet is used to manage the entire network configuration for a tenant. It can be used with a data object created from an imported CSV to upload or update the network topology, including sites, regions, and subnets, in a single bulk operation. This is the correct and most efficient method for importing a comprehensive network topology from a file.

For Teams Rooms on Windows, the SkypeSettings.xml configuration file must be placed in the C:\Users\Skype\AppData\Local\Packages\Microsoft.SkypeRoomSystem_8wekyb3d8bbwe\LocalState directory. The Teams Rooms application process, running under the 'Skype' user account, reads this file at startup to apply any custom configurations.

Microsoft eCDN relies on WebRTC for peer-to-peer communication between clients on the same local network. This communication primarily uses UDP over a range of ports (often including the standard STUN/TURN ports 3478-3481). If a local firewall or network access control list (ACL) is blocking this peer-to-peer UDP traffic, clients cannot discover each other or share video segments, forcing them to fetch content directly from the internet and defeating the purpose of the eCDN.

For any phone number that can be used for outbound calling, including the number on a resource account used for Shared Calling, an emergency address must be assigned to it. This is a mandatory step for E911 compliance. If the emergency address is not set for the number, outbound calling will be blocked.

The Teams Rooms Pro Management portal is specifically designed for advanced management, monitoring, and reporting of Teams Rooms devices. Its 'Reports' section provides detailed analytics on usage, device health, meeting reliability, and hardware inventory, which directly addresses all the manager's requirements.

Local Media Optimization (LMO) is specifically designed for this scenario. It allows media traffic (the actual voice stream) to flow directly between the Teams client and the nearest SBC (e.g., one in Europe), while SIP signaling (call control) still goes to the central Microsoft 365 servers and follows the central routing policies. This avoids media hairpinning and significantly reduces latency, improving call quality for users at remote sites.
