If you would like to have your clients displaying numbers of
incoming calls (you need i4l, isdn for linux), you have to
configure LineControl Server so that it knows the format
of the data on its standard input coming from isdnlog.
Furthermore you have to start isdnlog and linesrv in a pipe
so that stdout of isdnlog goes to stdin of linesrv.
The two scripts start isdnlog and linesrv to have this
working. For the rest you should have a look at the
complete-syntax configfile (somewhere in this distro
included, it's easy to find :).
