     isdntel -- isdn4bsd telephone answering management utility

     isdntel [-a aliasfile] [-d spooldir] [-p playcommand] [-t timeout]

     isdntel is used to provide an ``answering machine'' functionality for
     incoming telephone voice messages.

     The following options are supported:

     -a      Use aliasfile as the pathname for an aliasfile containing aliases
             for phone numbers. The default path is /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.

     -d      Use spooldir as the directory where the incoming voice messages
             are stored by the ``answ'' script called by isdnd(8).  This
             defaults to the directory /var/isdn.  The format of a voice mes-
             sage filename is:


     -p      Use playcommand as the command string to execute for playing a
             voice message to some audio output facility. The characters %s
             are replaced by the currently selected filename. The default
             string is cat %s | alaw2ulaw >/dev/audio

     -t      The value for timeout specifies the time in seconds the program
             rereads the spool directory when there is no keyboard activity.

     The screen output should be obvious. If in doubt, consult the source.
