is a simple answering machine using the H.323 protocol.
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.
All of the command line options to
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
Set the directory that record files are created in to dir.
Disable the specified codec (may be used multiple times).
Upon startup, register only with the specified gatekeeper rather than
attempting to find a gatekeeper by using UDP broadcast.
Set outgoing message for G.711 codec to filename.
Set outgoing message for G.723.1 codec to filename.
Set outgoing message for GSM codec to filename.
Display the help message.
Only bind to the specified network interface address.
automatically listens for incoming calls on all TCP/IP network interfaces
available on the host machine. This option is useful for running multiple
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
Kill recorded files after user command.
Limit recorded messages to a duration of secs seconds (defaults to 30).
Listen on the specified tcp port instead of the default 1720.
Set outgoing message to filename.
Do not attempt to find a gatekeeper upon startup using UDP broadcast.
Write trace output (enabled with the -t option) to the specified file
rather than to stderr.
Set outgoing message for PCM derived codecs (G.711/GSM) to filename.
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.
Exit if a gatekeeper cannot be found.
Run the command specified as cmd after each recorded message.
Save arguments in configuration file.
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.
Set the local endpoint name to str. Default is "OpenH323 Answering
options can be set in the openam configuration file
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
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.
