There are two parts to this topic:
1) Completed: Bypass the lobby for PSTN: The ability for admins and organizers to be able to specify a meeting option to bypass the PSTN lobby independently of the VoIP lobby.
2) On the backlog: Ability for an organizer joined via PSTN to admit users from the lobby with a PIN. If you enable “Always let callers bypass the lobby” in your meeting options, people calling in by phone will join your meeting without having to wait for someone to admit them. See details here: https://support.microsoft.com/office/change-participant-settings-for-a-teams-meeting-53261366-dbd5-45f9-aae9-a70e6354f88e
Please Note: In Q2CY20, we launched a new default in for the Teams meeting policy (https://www.microsoft.com/microsoft-365/roadmap?filters=&searchterms=63388). If tenants have not modified their default meeting policy, lobby is now enforced.

I have a user that is having the same issue. The user created a audio conferencing meeting and added me an a test. I called first from my personal cell phone and got put into the waiting room. The user joins the call and enters their PIN code. The user is in the room but i'm still in the waiting room. The use said it has been working the past week until today.
