+.Sh NAME
+.Nm isdnphone
+.Nd telephone dialing and more for isdn4bsd
+.Sh SYNOPSIS
+.Nm
+.Op Fl h
+.Op Fl n Ar number
+.Op Fl u Ar unit
+.Sh DESCRIPTION
+.Nm isdnphone
+is part of the isdn4bsd package and is used to handle dialing and hangup
+for the telephone control interfaces /dev/i4bteld<n>.
+.Pp
+Options are provided to dial out or hang up using commandline parameters
+(for use in scripts) or, if none of those options are specified, bring up
+a curses-based fullscreen interface.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl h
+hang up a possibly open telefone connection on the selected interface.
+.It Fl n
+dial the specified number on the selected interface.
+.It Fl u
+Set the unit number to specify the interface used.
+.Pp
+.Sh FILES
+/dev/i4bteld<n>
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+isdnphone -n 1234
+.Ed
+.Pp
+dials calls the number 1234 to establish a call on /dev/i4btel0
+.Sh AUTHOR
+The
+.Nm
+utility and this manpage were written by
