Well, what's "Telefonanlage" in english?? Until someone tells me, I'll
still call it telephone system ;)

Well, I didn't really have the idea of configuring my telephone system
to do that work for me... seems pretty easy that way. Anyway, the
problem is still the same to me, because I know lots of people who have
a telephone system that doesn't have such a function (my small company
included). What's more, people might be attaching up to seven (or was it
eight) modems (or terminal adaptors) to an ISDN-line without any
telephone system, so all these devices continue to get the RING at once.
Gert, no offense ment, but the behaviour of mgetty, if it gets several
rings at once coming from the same call, isn't plausible. I'll have to
see if I still got those old logs where you can see that two running
mgetty-instances kind of "take away" the call from each other.
Thanks very much for the useful advice anyway.
