I did some research when I created the series but could not find a definite list. All provides that I /could/ find seem to list the end-of-life date as either 2018 or 2019. Deutsche Telekom was by far the biggest provider and tried to finally shut it down in 2018, but apparently there are still a small number of households that are fighting the change to IP-only connections. [side rant: I do understand why -- when my parents were forced to change, their DSL speed dropped from barely usable (1024kb/s) to completely useless (256kb/s), and Deutsche Telekom refused to let them use an LTE home connection instead even though that is offered to half their neighbors in the same village and works fine in their house. They now have to pay for a DSL connection they can't use and an expensive handset LTE contract that is capped at 10GB per month] In Germany, Vodafone still offers physical ISDN lines until 2022, but only for business customers, and they try to get them to switch as well. > > CAPI in turn is not quite as obsolete, but as I have been unable to find > > any users, I would suggest moving it to drivers/staging while we > > figure out if anyone is using it.

Greg would know. I assume not, but that would be just because everyone who moved drivers into staging was guessing correctly that there were actually no users. > > If anyone is still using isdn4linux and CAPI with modern kernels, please > > speak up now. > > I'll try to test gigaset's drivers (in CAPI mode) until 5.2 is released (end > of July/early August).
