You have a Teams Phone deployment that uses Direct Routing and a legacy PBX.
You need to leverage the a PBX during outbound calls from scheduled Teams meeting.
What should you create?
Enable the routing of Teams meeting dial-out calls through Direct Routing
Teams meeting dial-out calls are initiated from within a meeting in your organization to PSTN numbers, including call-me-at calls and calls to bring new participants to a meeting.
To enable Teams meeting dial-out routing through Direct Routing to on-network users, you need to create and assign an Audio Conferencing routing policy called 'OnlineAudioConferencingRoutingPolicy'.
Note:
Direct Routing lets you connect a supported, customer-provided Session Border Controller (SBC) to Phone System. With this capability, you can configure on-premises Public Switched Telephone Network (PSTN) connectivity with Microsoft Teams client, as shown in the following diagram:

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are optimizing a network to better support voice and collaboration workloads in Microsoft Teams.
When the users are at a specific corporate site, you need to prevent the users from adding video during calls.
Solution: You run New-CsTeamsMeetingPolicy and set the -MediaBitRateKb parameter to 1.
Does this meet the goal?
Instead run New-CsTeamsNetworkRoamingPolicy and set the -AllowIPVideo parameter to $False.
Note: The New-CsTeamsNetworkRoamingPolicy cmdlet allows IT Admins to create policies for Network Roaming and Bandwidth Control experiences in Microsoft Teams.
The TeamsNetworkRoamingPolicy cmdlets enable administrators to provide specific settings from the TeamsMeetingPolicy to be rendered dynamically based upon the location of the Teams client. The TeamsNetworkRoamingPolicy cannot be granted to a user but instead can be assigned to a network site. The settings from the TeamsMeetingPolicy included are AllowIPVideo and MediaBitRateKb. When a Teams client is connected to a network site where a CsTeamRoamingPolicy is assigned, these two settings from the TeamsRoamingPolicy will be used instead of the settings from the TeamsMeetingPolicy.
