Derived Trunk for Teams direct routing hosting model

I am working on a case about Teams direct routing hosting model. After going through the article about 'Configure a Session Border Controller for multiple tenants' https://docs.microsoft.com/en-us/m...

Hi seanwerner 

 

sorry for replying old thread. I am curious with the part where you assigned E1/E3 + PS on dummy user at derived subdomain inside customer tenant. As I am sure that I have two tenants with derived domain that didnt need to enable these licenses since early 2019. Is this latest requirement from MS?

godril I tested this to see if you could assign just the E3 license to activate then remove the license, this stopped functions of the Direct routing from working, e.g. Outbound CLI.

 

FYI: you only need to assign an E3/E5 license not the phone system license to this dummy user on the subdomain, this is to activate this domain. never tried it with an E1 (does it work?)

    TeamsDR  E1 works just fine. But actually I can remove  all license at all for the SIP trunk. It's been  2 years now. Should I not discuss this here? :)))

    TeamsDR I tested assigning the license and removed the license after seeing the FQDN in the result of 

    Get-CsTenant | fl Domain*

    It works fine
