Hello @Mark ,
If I'm understanding correctly you are trying to check from MS Teams if CVI is already configured? If so, you will need to run the following PowerShell command:
Get-CsVideoInteropServiceProvider
Refer to:
https://docs.microsoft.com/en-us/powershell/module/skype/get-csvideointeropserviceprovider?view=skype-ps
The TenantKey/Video Address will tell you which Webex Organization is using the integration.
[WebexOrg]@m.webex.com
