For Direct Routing, the SBC's PSTN gateway configuration must have PidfloSupported set to True so location information is added to the outgoing emergency INVITE; in the Teams admin center this is the SBC setting 'SBC supports PIDF/LO for emergency calls', and in PowerShell it is Set-CsOnlinePSTNGateway -PidfloSupported $true, checked with Get-CsOnlinePSTNGateway.
