Many thanks for answering.

As Jan has pointed out in his reply, ISDN is very timing sensitive, so =
an emulation (which is in user space) might not work at all. Furthermor=
e, we don't have the resources to write such an emulation, and I doubt =
that somebody else will do it.

=46ax via VOIP still does not work reliably, so there must be many peop=
le who need ISDN in virtualized guests. I am wondering how other people=
 are dealing with that problem.
