Org Guests are being sent straight to Voicemail

LinusCansby Thank you for checking. Several users (not guests) were seemingly affected and calls from any guest were going straight to their voicemail.

I actually discovered what the problem was. These users were previously licensed with PSTN/Phone System/Call plans, and while they had those plans active, had set their Call settings to immediately "Forward to VM". Since then, the PSTN/Calling Plan licenses were removed from these users, however, their account settings are now stuck in "Forward to voicemail" with no way to change it, because they no longer get access to the settings for Call handling (why this limitation? I have no idea...).

What I have had to do was re-assign a calling plan/phone system license to the affected users in order to regain access to the Call handling settings in the Teams app, to take forwarding off. Maybe could have been done via PowerShell, IDK. Obscure, but quite annoying bug.
