yesterday and today marks the first time we've transmitted Telefax G4 over our OCTOI #retronetworking community ISDN-over-IP network using an actual historical G4 capable fax machine (Canon FAX-L260i) - the machine itself can print D- and B-channel protocol traces!
I just received an invoice from ITU
(International Telecommunications Union). Their letterhead states a TELETEX number (in 2024!). I love it. #retronetworking - now I seriously wonder how I might be able to get connected to a public network that can reach it.
