Derived Trunk for Teams direct routing hosting model
Hi Vasileios_T,
Before you can add the Voice Routes, you need to add the tenant-specific sub-domain to the customer's Office 365 tenant, as an additional domain.
EG:
Carrier: hosted.example.com
Cust 1: cust1.hosted.example.com
Once you've added the sub-domain for the customer & added the TXT record to the carrier's DNS to authorise the sub-domain addition, you then create a dummy user within the new domain, with a S4B Online license at least.
EG:
test.user@cust1.hosted.example.com - licensed with E3/E5 etc.
The license only needs to be assigned for 30/60 minutes while the platform activates the domain.
Following this, you should then be able to create the voice routes etc. as you've attempted.
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?)
