Teams Auto Attendant, Hybrid Application Endpoint, On-Prem URI

Copper Contributor

Hello,

 

I'm not sure if this would be better suited here or in one of the Teams communities, but it seems to be a specific use case for SfB server.

 

We are trying to retire the old Exchange 2016 and migrate the Auto Attendants but have hit a road-block.

 

We have a few legacy UCMA applications utilizing trusted application endpoints.  We're trying to get them migrated to Teams bots, but the timing likely isn't going to work out.  In the meantime, we are unable to route calls to these on-prem application endpoint accounts from the Teams AA.

 

The Teams AA are using resource accounts created with New-CsHybridApplicationEndpoint, but it seems that the on-prem TrustedApplicationEndpoint objects aren't synchronized to M365 as they appear to be in one of the hidden OUs only accessible in ADSIEdit, or at the very least their URI is not visible to Teams.

 

Has anyone ran into this oddly specific problem and know of any work around? Relevant thread: https://techcommunity.microsoft.com/t5/microsoft-teams/trusted-application-endpoints-in-teams/m-p/80...

 

Thanks!
