Does anyone know of any communities / mailing lists / newsgroups / et al. for retro networking / WAN technologies?- PSTN / PBX / PABX
There is a Central Office Groups.io list (which migrated from Yahoo Groups) located at https://groups.io/g/centraloffice . It is low traffic.
There is a Discord server related to PBX and Telephone stuff, but will have to dig up that info later. It's pretty low traffic as well.
