Please standardize on the name for Audio Conferencing within the admin centers, documentation, emails sent to users, etc. I realize it started out as Skype for Business PSTN Conferencing, then was changed to Microsoft Audio Conferencing. Now it looks like it's called Office 365 Audio Conferencing, according to the "You now have Office 365 Audio Conferencing" email users receive when the license is assigned. We had a user delete this email, thinking it was spam, because the From display name is "Skype for Business". Please change the From display name to correctly reflect the product name (e.g., "Office 365 Audio Conferencing".
