Just following up to let you know we are making progress on this feature and will post when we have more news to share.

When our PABX user calls a Teams user via Ribbon SBC Direct Route, the toast popup shows the CNAM (based on SIP INVITE FROM field), but in the Teams call history, it just shows numbers. We have modified the Telephone field for all AD users to include the full E.164 phone number, which is synching to Azure AD. But Teams fails to lookup the number against Azure AD in order to find the user display name. So from a Call History perspective, RNL is still not working.
We absolutely need Teams to show DisplayName instead of phone number in the Call-History page.
Thanks for your recent update Alex. Looks like Microsoft is working on this specifically.
