NAME
ohphone - initiate, or receive, a H.323 IP telephony callSYNOPSIS
ohphone -l|--listen [options]...ohphone [options]... address
DESCRIPTION
ohphone is a command line application that can be used to listen for incoming H.323 calls, or to initiate a call to a remote host. Although originally intended as a test harneess for the OpenH323 project (see http://www.openh323.org) it has developed into a fully functional H.323 endpoint application. ohphone includes a simple menu that allows interactive control of functions, as well as allowing control of most dialling and answer functions via a phone handset when used with a Quicknet (see http://www.quicknet.com) LineJack or PhoneJack.
When used with the -l option, ohphone will wait for incoming calls. If this option is not specified, ohphone 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 ohphone 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 ohphone configuration file. To disable or turn off a feature, use the long form of the name with the prefix --no-, i.e. --no-answer or --no-gsm.
- -a, --auto-answer
- Automatically answer incoming calls.
- --aec level
- Set the AEC (audio echo cancellation) level when using a Quicknet card. level must be in the range 0 through 3. The default value is 2.
- --autohook
- Automatically handle hook state for phone devices that appear permanently off-hook. This option is intended for use with the Quicknet PhoneCARD.
- --answer-timeout time
- Time in seconds till forward on no answer.
- -b, --bandwidth bps
- Limit bandwidth usage reported to gatekeeper to bps bits/second.

- --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.
- --sound-playvol vol
- Set the playback volume when a sound card is used. This overrides the value of --playvol (if set). The volume is an integer value from 0 through 100
- --sound-recvol vol
- Set the record volume when a sound card is used. This overrides the value of --recvol (if set). The volume is an integer value from 0 through 100
- --stun stun_server
- Set to use the specified STUN server. STUN (Simple Traversal of UDP Through NAT) is a protocol that allows a mahine behind NAT to figure out the public IP address and port number of a UDP socket, by querying a STUN server running on the Internet. ohohone then uses this public IP address and port number for H.323 signaling. If you are behind a NAT or firewall, and know the IP address of a STUN server, to get ohphone to work you do not need to set up port forwarding or put your machine in DMZ, ohphone will utilize the STUN server to use the correct IP address and port numbers for signaling. For example, typing `ohphone -n --stun stun.somewhere.com friend.otherplace.com' starts ohphone to call the machine friend.otherplace.com and uses the STUN server at stun.somewhere.com.
- -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. ohphone has trace statements up to level 5. Use the -o option to write the trace information to a file rather than to stderr.
- --tos value

CONFIGURATION FILE
ohphone options and speed dials can be set in the ohphone configuration file ~/.pwlib_config/ohphone.ini . This config file is divided into sections, with each section indentified by a header enclosed in square brackets. Options must be located in the section prefixed with [Options], whilst speed dials must be located in the section prefixed [Speedial]. The long form of any command line option specified above can be specified in the configuration file, in the format:
- option = value
SPEED DIALS
ohphone can be configured to dial an IP address upon entering a speed dial code conisisting of an integer followed by the hash (#) character. Speed dial codes are available via the menu "C" command (see the MENU section) or via the phone handset (if a Quicknet card is used). ohphone Speed dials are configured using the menu "D" command, or can be added directly to the [SpeedDials] section of the configuration file (see below).
Speed dials can also contain wild card characters which allow groups of numbers to be assigned to specific gateways. The following examples show the use of wild cards:
- 7?? @192.168.5.3
- Dial three digit numbers starting with 7 through the gateway at 192.168.5.3
- 9* %192.168.7.1
- Dial any number starting with 9 through the gateway at 192.168.6.3, but strip the leading 9 before dialling.
The following special speed dials can also be used:
- #
- Redial the previously dialled number
- *#
- Dial the previous caller
DIALLING IP NUMBERS USING A HANDSET
An IP number can be dialled using a phone handset connected to a Quicknet card. This is done by pushing the star (*) button, and then entering the IP number using the star (*) button to seperate each of the four parts of the IP address, and then pressing the (#) button. For example, the sequence below can be used to dial the IP address 192.168.64.5:- *192*168*64*5#
INTERNAL MENU
ohphone allows the user to perform various operations whilst listening for an incoming connection, or whilst a call is in progress. These operations are accessed via single line commands which each start with a single character identifying the function. The available commands are:
- Q or X
- Hangup any active calls and exit the program.
- H
- Hangup any active calls.
- C address [gateway]
- Initiate a call to the specified host or IP address. If the optional getway paramater is used, then the specified gateway will be used to make the call. If the address ends with the hash (#) character, it is assumed to be a Speed Dial code.
- L
- List all current speed dial codes
- D code address
- Create a new speed dial for address using code.
- S
- Print statistics of the call in progress.
- P
- Toggle between speakerphone and normal mode
- A
- Turn AEC up by one level (Quicknet cards only)
- a
- Turn AEC down by one level (Quicknet cards only)
- [
- Turn play volume up by one level.
- ]
- Turn play volume down by one level.
- }
- Turn record volume up by one level.
- {
- Turn record volume down by one level.
- V
- Display current volume settings
- E
- Toggle silence supression
- I
- Show last 16 calls made
- i
- Show last 16 calls received
EXAMPLES
- ohphone -l
- Find a gatekeeper on the local network, register with it, and then listen for incoming calls.
- ohphone -ln
- Listen for calls without registering with a gatekeeper.
- ohphone -ln -q0 --callerid
- Listen for calls without registering with a gatekeeper, using /dev/phone0 (a Quicknet card) as the sound device, and enabling transmission of caller ID to the handset on incoming calls.
- ohphone -n ipaddress
- Make a call using directly to another endpoint without a gatekeeper
- ohphone -n ipaddress
- Make a call using directly to another endpoint without a gatekeeper
FILES
~/.pwlib_config/ohphone.ini
USING MICRO TELCO WITH OHPHONE
Use of microtelco only happens if you have a valid microtelco account and a quicknet card installed on your computer. Add to the command line the following four entitites.
-u microtelco_account_number
--password microtelco_pin_number
-g gk.microtelco.com
Specify a quicknet card, say, -q0, to get /dev/phone0.
BUGS
Picking up a handset after initiating a call using the menu C comment sometimes produces odd results
Quicknet cards seem to change playback volume when calls are started - sometimes!
