Notice! isdn4net now have a new maintainer! (2003-08-12)

I'm happy to announce that isdn4net now have a new maintainer, Steffen Barszus, who is working on a new release with more features. Please contact him if you have comments or suggestions.
I'm sorry that I haven't been able to keep up working on isdn4net for a while, but as I now have a cable connection and no more ISDN lines (or bills ;) it is rather difficult (and pointless) to keep maintaining it. I will keep this site online for reference, but it will not be updated - Steffen is planning to setup a new and updated isdn4net site in the future.
Thanks to everyone who have contributed to isdn4net with problem reports, patches, and general comments during the years. I have recived a lot of positive comments/usage reports during this time, and belive isdn4net is still running on a lot of linuxboxes around the world (I'm still interested in isdn4net usage reports btw, so if you have runned it for many years or have some special setup like dialin etc let me know).
isdn4net is a true GPL product, made by it's users for it's users - I hope it will still be providing isdn access for many many years, and wish Steffen the best of luck with the future maintance and releases!
