NAME
simph323 - simple H.323 client given as an example
SYNOPSIS
simph323 -l|--listen [options]...
simph323 [options]... address
DESCRIPTION
simph323 is a command line application that is given as an example of
what you can do with openh323, it is a simple h323 client that can be
used to listen for incoming H.323 calls, or to initiate a call to a
remote host, however, if you want a real h323 client I’d suggest you
check out ohphone.
simph323 includes a really simple prompt where you can pick up incoming
calls or reject them as they arrive, also hang up active calls (with
the h command) and exit the program (with the x command).
When used with the -l option, simph323 will wait for incoming calls. If
this option is not specified, simph323 expects a hostname to be
specified and will attempt to connect to a H.323 client at that
address.
OPTIONS
All of the command line options to simph323 can be specified in long
form, and the most commonly used options also have single character
equivalents.
-a, --auto-answer
Automatically answer incoming calls.
-b, --bandwidth bps
Limit bandwidth usage reported to gatekeeper to bps bits/second.
-D, --disable codec
Disable the specified codec (may be used multiple times).
-f, --fast-disable
Do not request H323V2 FastConnect when initiaiting a connection.
-B, --forward-busy party
Forward the call to the remote party if busy.
-g, --gatekeeper host
Upon startup, register only with the specified gatekeeper rather
than attempting to find a gatekeeper by using UDP broadcast.
-T, --h245tunneldisable
Do not perform H245 tunneling when initiating a connection.
-h, --help
Show help message.
-i, --interface interface
Only bind to the specified network interface address. By
default, simph323 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 simph323 on
the same multi-homed machine, or for ensuring that only calls
from the external, or internal, network will be received on a
particular handset.
-j, --jitter delay
Set jitter buffer to delay ms. By default, the jitter buffer is
set to 50 ms.
-l, --listen
Listen for incoming calls.
-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.
-P, --prefer codec
Prefer the specified codec (may be used multiple times).
-r, --require-gatekeeper
Exit if a gatekeeper cannot be found.
-e, --silence
Disable silence detection and removal for GSM and software
G.711.
-s, --sound device
Select the sound input and output device. The default value is
/dev/dsp0.
--sound-in, --sound-out device
Select the sound input or output device seperately. Only needed
if different sound devices are needed for input and output.
-t, --trace
Enable debug tracing, which displays messages at run-time to
assist in debugging or problem identification. Specifying this
option multiple time increases the amount of information
displayed. simph323 has trace statements up to level 5. Use the
-o option to write the trace information to a file rather than
to stderr.
-u, --user name
Set local endpoint alias name. Can be used multiple times to add
multiple aliases. By default, the alias list contains a single
entry with the current user’s login name.
EXAMPLES
simph323 -l
Find a gatekeeper on the local network, register with it, and
then listen for incoming calls.
simph323 -ln
Listen for calls without registering with a gatekeeper.
simph323 -n ipaddress
Make a call directly to another endpoint without using a
gatekeeper
