Initial entry of ISDN4BSD into the FreeBSD tree.

ISDN4BSD is the work of our brand-new comitter: Hellmuth Michaelis,
who has done a tremendous amount of work to bring us this far.

There are still some outstanding issues and files to bring into
the tree, and for now it will be needed to pick up all the extra
docs from the isdn4bsd release.

It is probably also a very good idea to subscribe to the isdn@freebsd.org
mailing list before you try this out.

These files correspond to release "beta Version 0.70.00 / December
1998" from Hellmuth.

+.Sh NAME
+.Nm isdntel
+.Nd isdn4bsd telephone answering management utility
+.Sh SYNOPSIS
+.Nm isdntel
+.Op Fl a Ar aliasfile
+.Op Fl d Ar spooldir
+.Op Fl p Ar playcommand
+.Op Fl t Ar timeout
+.Sh DESCRIPTION
+.Nm
+is used to provide an "answering machine" functionality for incoming
+telephone voice messages.
+.Pp
+The following options are supported:
+.Bl -tag -width Ds
+.It Fl a
+Use 
+.Ar aliasfile
+as the pathname for an aliasfile containing aliases for phone numbers. The
+default path is
+.Em /etc/isdn/isdntel.alias .
+The format of an alias entry is the number string followed by one or more
+spaces or tabs. The rest of the line is taken as the alias string. Comments
+are introduced by a leading blank, tab or "#" character.
+.It Fl d
+Use
+.Ar spooldir
+as the directory where the incoming voice messages are stored by the
+"answ" script called by 
+.Xr isdnd 8 .
+This defaults to the directory
+.Em /var/isdn .
+The format of a voice message filename is:
+.Pp
+.Dl YYMMDDhhmmss-dest_number-source_number-length_in_secs
+.It Fl p
+Use
+.Ar playcommand
+as the command string to execute for playing a voice message to some audio
+output facility. The characters
+.Em %s
+are replaced by the currently selected filename. The default string is
+.Em cat %s | alaw2ulaw >/dev/audio
+.It Fl t
+The value for
+.Ar timeout
+specifies the time in seconds the program rereads the spool directory
+when there is no keyboard activity.
+.El
+.Pp
+The screen output should be obvious. If in doubt, consult the source.
+.Sh SEE ALSO
