NAME

     isdntelctl -- control isdn4bsd telephone sound format conversion

SYNOPSIS

     isdntelctl [-c] [-g] [-u unit] [-A] [-U] [-N]

DESCRIPTION

     isdntelctl is part of the isdn4bsd package and is used to configure the sound format conversion facilities of the /dev/isdntel interfaces.

     The following options are available:

     -c      Clear the telephone input queue.

     -g      Get the sound format currently in use.

     -u      Set the /dev/isdntel unit number.	The default value is zero to access device /dev/isdntel0.

     -A      Do A-law (ISDN line) -> mu-law (userland) conversion.

     -U      Do mu-law (ISDN line) -> A-law (userland) conversion.

     -N      Set sound conversion to do no format conversion.

     The telephony data stream comes out of the line in a bit-reversed format, so the isdntel(4) driver does the bit-reversion process in any
     case.

     Additionally, the user can specify to do A-law to mu-law, mu-law to A-law or no conversion at all in the isdntel driver by using the
     isdntelctl utility.

FILES

     /dev/isdntel<n>

EXAMPLES

     The command

	   isdntelctl -g

     displays the currently used sound format for device /dev/isdntel0.

STANDARDS

     A-law and mu-law are specified in ITU Recommendation G.711.

NAME

     isdntel -- isdn4bsd telephone answering management utility

SYNOPSIS

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

DESCRIPTION

     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 message filename is:

		   YYMMDDhhmmss-dest_number-source_number-length_in_secs

     -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.
