Auto Attendant numbers are not working.

I have allocated a telephone number to a resource account - We are receiving a SIP response back of 480 temporarily unavailable. Our phone system is Direct Routing. Can you please advise.

    Ran into this today and found your post.

    For me, I originally used the old command starting with "Set-CsOnlineApplicationInstance" as we had in the past but calls were not working. So I removed the TN from the Resource Account, waited about 5 minutes and then ran "get-CsOnlineApplicationInstance" to verify that resource account no longer showed a phone number.

    I then had to update the PowerShell teams module using: Update-module MicrosoftTeams

    Close PowerShell and reopen it. Connect-MicorsoftTeams

    I then ran the new command (example)
    Set-CsPhoneNumberAssignment -Identity Email address removed -PhoneNumber +15555555 -PhoneNumberType DirectRouting

    Not sure, but the new command allows you to specify the "PhoneNumberType DirectRouting".
