NAME
gnugk -- The GNU Gatekeeper SYNOPSIS
gnugk [-hdrt] [-c filename] [-s section] [-i IP] [-l n] [-b n] [-u name] [-d name] [-rr] [-o filename] [--pid filename] [--core n] DESCRIPTION
The GNU Gatekeeper is an open-source project that implements a H.323 gatekeeper. A H.323 gatekeeper controls all H.323 clients in its zone. It allows you, among other things, to register devices, make calls, perform AAA (Authentication, Authorization and Auditing), manage configu- rations at runtime and traverse NAT. OPTIONS
The behavior of the gatekeeper is determined through command line options and the configuration file. Some command line options may override settings found in the configuration file. For example, the option -l overrides the setting "TimeToLive" in the configuration file. Almost every option has a short and a long format, e.g., -c is the same as --config. -h --help Show all available options and quit the program. -c --config filename Specify the configuration file to use. -s --section section Specify which main section to use in the configuration file. The default is [Gatekeeper::Main]. -i --interface IP Specify the IP address that the gatekeeper listens to. You should leave out this option to let the gatekeeper automatically determine the IP it listens to, unless you want the gatekeeper to bind to a specified IP. -l --timetolive n Specify the time-to-live timer (in seconds) for endpoint registration. This overrides the setting "TimeToLive" in the configuration file. A detailed explanation can be found in the manual. -b --bandwidth n Specify the total bandwidth available for the gatekeeper. Without specifying this option, bandwidth management is disabled by default. --pid filename Specify the pid file. Only valid for Unix version. -u --user name Run the gatekeeper process as this user. Only valid for Unix versions. --core n (Unix only) Enable writing core dump files when the application crashes. A core dump file will not exceed n bytes in size. A special constant "unlimited" may also be specified. Gatekeeper Mode The options in this subsection override the settings in the [RoutedMode] section of the configuration file. -d --direct Use direct endpoint call signaling. -r --routed Use gatekeeper routed call signaling. -rr --h245routed Use gatekeeper routed call signaling and H.245 control channel. Debug Information -o --output filename Write trace log to the specified file. -t --trace Set trace verbosity. The more -t you add, the more verbose to output. For example, use -ttttt to set the trace level to 5. FILES

NAME
openam - H.323 answering machine SYNOPSIS
openam [options]... DESCRIPTION
openam is a simple answering machine using the H.323 protocol. openam works by setting up a H.323 listener process, and then waiting for incoming connections. Whenever an incoming connection is established, it plays the outgoing message (OGM) and then starts recording any incoming audio from the remote end into a record file. OPTIONS
All of the command line options to openam can be specified in long form, and the most commonly used options also have single character equivalents. The long forms can also be used in the openam configuration file. -d, --directory dir Set the directory that record files are created in to dir. -D, --disable codec Disable the specified codec (may be used multiple times). -g, --gatekeeper host Upon startup, register only with the specified gatekeeper rather than attempting to find a gatekeeper by using UDP broadcast. --g711message filename Set outgoing message for G.711 codec to filename. --g7231message filename Set outgoing message for G.723.1 codec to filename. --gsmmessage filename Set outgoing message for GSM codec to filename. -h, --help Display the help message. -i, --interface IP Only bind to the specified network interface address. By default, openam automatically listens for incoming calls on all TCP/IP network interfaces available on the host machine. This option is useful for running multiple copies of openam on the same multi-homed machine, or for ensuring that only calls from the external, or internal, network will be received on a particular answering machine. -k, --kill Kill recorded files after user command. -l, --limit secs Limit recorded messages to a duration of secs seconds (defaults to 30). --listenport port Listen on the specified tcp port instead of the default 1720. -m, --message filename Set outgoing message to filename. -n, --no-gatekeeper Do not attempt to find a gatekeeper upon startup using UDP broadcast. -o, --output filename Write trace output (enabled with the -t option) to the specified file rather than to stderr. --pcmmessage filename Set outgoing message for PCM derived codecs (G.711/GSM) to filename. -P, --prefer codec Sets the prefered codec to the specified codec. If used multiple times, it specifies an order in preference, being the first one specified the most prefered one. --require-gatekeeper Exit if a gatekeeper cannot be found. -r, --run cmd Run the command specified as cmd after each recorded message. --save Save arguments in configuration file. -t, --trace Enable debug tracing, which displays messages at run-time to assist in debugging or problem identification. Specifying this option multiple times increases the amount of information displayed. Use the -o option to write the trace information to a file rather than to stderr. -u, --username str Set the local endpoint name to str. Default is "OpenH323 Answering Machine vxxx". CONFIGURATION FILE
openam options can be set in the openam configuration file ~/.pwlib_config/openam.ini either by edditing this file or via the --save option. Options must be located in the section prefixed with [Options]. The long form of any command line option specified above can be specified in the configuration file, in the format: option = value EXAMPLES
openam -n -m hello Start the program without registering with a gatekeeper using message on file hello.sw or hello.g723 depending on the codec. openam -m sample_message -r new_msg Start the answer machine searching for a gatekeeper to register with, using the examples "sample_message" and "new_msg" respectively as the answering message and the script to be run after each recorded message.
