This is case of deja vu (https://community.spiceworks.com/topic/1032589-office-365-litigation-hold-licensing)
I want to purchase the ability for users to have the PSTN conferencing feature added to their Business Essentials license. I don't need E5 as I'm an SMB. Am I blind or can I not purchase this? If there is a creative way to purchase this without paying a lot of money I'm open to that as well.

I also have a departmentthat I'm thinking of getting cloud PBX and PSTN dialing for as a trial basis before going full blown for everyone and I can't figure out how to do that either with their Business Essentials licenses.
