No RingBack when using Microsoft Teams Direct Routing

Recently we have decomissioned our Microsoft Cloud Connector Edition and migrated most of our telephony users to Microsoft Teams with Direct Routing. One big issue we faced was that when a external caller called us by PSTN, they only heard one RingBack tone followed by deadly silence till someone picked up or landed in Azure VoiceMail. Thanks to my friend Goos Stuut, working at our local distri for Audiocodes we found out what was happening and we solved this issue.
