Any workaround for Extension dialing from cloud auto attendant

Hello,

As you know that extension dialing from cloud auto attendant is not working as it is not a feature yet, but Microsoft has this feature in their road-map.

My question is does anyone find any workaround to make it works? What about Auto Attendant in Exchange Online. I know that Exchange Online Unified Messaging will be retiring in February 2020, but until that date does it work with Microsoft Teams direct routing?

Thanks in advance!
