2019

The project started around 2019, when Harald "LaF0rge" Welte started to document some of the ISDN and other equipment he had previously collected.

2022

In 2022, we started to operate the OCTOI (Osmocom Community TDM-over-IP) network, using which we can interconnect ISDN equipment over the internet.

We also had our first exhibit of ISDN + Modem gear at VCFB (Vintage Coputing Festival Berlin) 2022.

2023

In 2023, some of us rescued first one (later multiple) Siemens EWSD digital telephone exchange switches.

We also successfully operated an ISDN/PSTN network at the Chaos Communication Camp 2023 using V5 access network equipment (Siemens Fastlink, Nokia EKSOS) and our osmo-v5 implementation of the V5 LE side

2024

In 2024, we started this new homepage which you're reading here, as a more structured introduction to our work than the sometimes a bit hard to navigate redmine wikis.

Like in the previous year, we again had an ISDN Museum themed exhibition at Classic Computing 2024

We are also operating an ISDN/PSTN network at the Chaos Communication Congress. Unlike the 2023 camp, this time we will operate an actual Siemens EWSD telephone exchange on-site at the event.
