Controlling the Look and Feel of SGImeeting

There are a number of ways in which you can control the way SGImeeting appears on your desktop.

	Run in background This option allows you to close SGImeeting, but keep a small task running in the background to listen for incoming calls. When a call is received, SGImeeting re-opens on your desktop. To run SGImeeting in the background: Start SGImeeting as normal. Select Call, Run in Background. Close SGImeeting. Alternatively, to start SGImeeting in the background, use the following command: sgimeeting -runinbackground
	Always on top (This feature is not available on all platforms) You can choose to have the SGImeeting window always remain on top of all other windows. In this mode, other windows can gain the focus, but they will always appear behind the SGImeeting window. To choose this mode, select the Always On Top command on the View menu. This mode can be turned off in two ways: Select the Always on Top command on the View menu. Click three times in rapid succession (treble-click) on another window's title bar.
	Compact view In compact view, the SGImeeting user interface is reduced to its minimum size, showing just the title bar and the menu. This occupies as little space on the screen as possible but shows no status information. You can switch to compact view by doing any one of the following: Select Compact View on the View menu. Press Ctrl-Shift-C. Click the rollup icon (the tall thin button) at the left hand end of the SGImeeting toolbar. You can switch back from compact view by doing any one of the following: Select Compact View on the View menu. Press Ctrl-Shift-C. Resize the window by dragging its borders in the usual way.
	Other Look and Feel options Other ways in which you can customize the operation of SGImeeting include: Do Not Disturb Switching views.

Using SGImeeting through a firewall

If you are connected to the Internet through a firewall (as is usual in most corporate/LAN environments), you can use SGImeeting to communicate with others located both inside and outside the firewall. To enable full external communication, you need to do the following:

Make sure your workstation has its default gateway set to the internal address of the firewall computer.

Configure the firewall to allow primary TCP connections over the following IP ports:

389 (for communication with Internet Locator Servers)
1503 (for T.120 data)

(If this is not possible with your firewall, you will not be able to communicate with computers outside the firewall. Consult your firewall vendor about upgrading to a version compatible with NetMeeting and SGImeeting.)

Configure the firewall to map internal IP addresses to external Internet addresses.

(This is not possible with all firewalls. If your firewall cannot do this, you will be able to call out from inside the firewall, but you will not be able to receive incoming calls from computers outside the firewall.)

If you are unsure whether you are connecting to the Internet through a firewall, consult your system administrator or Internet service provider.

Installing and using TrueType fonts with SGImeeting

SGImeeting is designed to take advantage of a TrueType font server, if one is installed on your system (or accessible to your system across a local area network). For details on how to configure SGImeeting to use a TrueType font server, see the SGImeeting Configuration Guide.

With a TrueType font server installed, SGImeeting will have more fonts in common with Windows systems, resulting in better quality output and improved performance in sharing sessions involving both Windows and UNIX systems.

Calling into a Conference Server / Multipoint Conferencing Unit (MCU)

SGImeeting fully supports conferences hosted on Conference Servers, and has been tested with

	Outreach ConferEase
	DataBeam neT.120.

When calling an MCU, specify the address of the MCU as normal. You can also specify the name of the conference to join. If you do not specify a conference name, and SGImeeting detects that the machine called is currently hosting more than one conference, you are asked which conference you want to join. Note that hidden conferences are not included in the list of available conferences: you must specify the conference name when calling into the computer.

Uninstalling SGImeeting

To remove SGImeeting from your computer, use Software Manager (following the relevant instructions in the Software Manager online Help). To open Software Manager from the Toolchest, choose System > Software Manager.

Alternatively, you can remove SGImeeting with shell commands:

Close SGImeeting, if it is running.
In a shell:
- Become super-user by entering the command su
- Enter versions remove sgimeeting

The uninstall process does not remove user-specific files from your home directory. If you are uninstalling SGImeeting and have no further use for the user-specific files (received files, address book entries and your SGImeeting configuration file), you can remove them. To do so:

	Change to your home directory.
	Type the command "`rm -rf .AddressBook .sgimeeting-rcv-files .sgimeeting`".
