If any of my above statements are true, you are totally barking up the wrong
tree and would be equally well served by trying to attach the phone line to
the antenna connector of your TV (don't try it, it wouldn't be good for
the
TV), hence any error messages, etc. have no bearing on the problem. If you
indeed are getting ISDN from the phone company, then reposting a more
specific scenario may get you help from someone more familiar with your
countries protocol.
In summary, you must start by determining if the phone line is analog (easy
to test), ISDN, or some sort of broadband data which would support VOIP.
Once you know that you can connect it to the proper interface card. At that
point if it doesn't work right, someone here may be able to help you with a
configuration file or something. At the moment what I have stated is about
all anyone can tell you. You appear to be quite a ways away from knowing
what you have.
