Important Information About Version 1.5 of Apple VideoPhone Lite:
Apple Support does not support free software. Users are advised that this software has been screened and all known crashing bugs have been addressed, however use of this software may uncover issues that were not known at the time of release. If you experience unusual or undesired behavior, please read the list of known problems below before you give us feedback.
• You will see warnings if you are trying to install Apple VideoPhone Lite 1.5 on a computer that already has a 1.0.x, 1.1 or 1.4 version of QuickTime™ Conferencing installed. Apple VideoPhone Lite 1.5 is not designed to support the QuickTime™ Conferencing H.320/ISDN Card. If you still wish to install Apple VideoPhone Lite on a computer with the QuickTime™ Conferencing H.320/ISDN Card installed, you must remove the "QTCSound" file from the Extensions Folder inside your System Folder before proceeding with the install. Previous versions of Apple Media Conference or Connectix VideoPhone may not function optimally after installing Apple VideoPhone Lite 1.5.
• Videoconferencing over 28.8 kbps modem connections requires the use of special video and sound compressors which are not included in this free version of Apple VideoPhone. For more information, consult the QuickTime™ Conferencing web site or purchase the Apple VideoPhone Kit which includes the full featured software, all necessary compressors, an extensive Apple Guide and an analog video camera.
•You may experience a problem with some Internet Service Providers (ISPs) where your modem connection is periodically dropped. The symptoms of this are that audio and video stops updating, but the application does not close. If this occurs, it is best to quit Apple VideoPhone Lite, disconnect from the ISP, reset your modem, reset your PPP connection, and then relaunch Apple VideoPhone Lite.
•You may notice that Apple VideoPhone Lite automatically redials your ISP a few minutes after the ISP has dropped your modem connection. This is normal if you have configured your Apple VideoPhone Lite preferences to register you on a 411 Directory Server. Apple VideoPhone Lite periodically tries to contact the server, and will try to re-establish the ISP connection if it was closed while the Apple VideoPhone Lite was launched. Unfortunately, you will not be able to make or receive calls once an ISP connection has dropped until you have followed the steps in the paragraph above. To avoid unattended ISP connections, it is best to quit the Apple VideoPhone Lite application before disconnecting from an ISP.
•Using CoolTalk with the RT24 audio compressor is not recommended between two machines connected via ethernet unless they have a router between them. In some cases, users may experience problems resulting from heavy usage in this configuration. Connecting via Internet link (either modem or direct connection) is not a problem.
•Apple VideoPhone Lite is designed to work with MacPPP 2.5.1. Users of other versions of PPP, including MacPPP 2.5 (included with OpenTransport 1.1.1 in the Extras Folder), FreePPP and OT-PPP may experience problems unless they make sure that MacPPP 2.5.1 is selected in the TCP/IP Control Panel before dialing an ISP to use Apple VideoPhone Lite.
Setup
The Apple VideoPhone Lite installer creates a new folder on your hard drive called "Apple VideoPhone Lite." Look inside this folder for the application icon.
• If using externally powered speakers, it is recommended that you use RCA-style connectors to connect to the left and right audio (the ones marked CD) on the back of the speakers, not to the Audio-in port (the stereo miniplug marked with the Mac icon). This will avoid a problem where low-level audio is cut off.
• The preferences file is now located in the Preferences folder inside the System Folder, in a folder called "Apple VideoPhone Lite." If you have installed over a previous version of Apple VideoPhone Lite, consider copying your old preferences file out of the application folder into this new folder. Most of your preferences will be retained if you do this.
• Connectix Color QuickCam users may experience problems when taking snapshots. Download the "Color QuickCam 2.1a Updater" from the Connectix web site at http://www.connectix.com/.
• Apple VideoPhone Lite is not intended for use on a computer running router software.
Launching
• Do not try to launch this version of Apple VideoPhone Lite with less than 3.5 megabytes of available RAM.
• If you wish to transmit a picture of yourself, copy a snapshot into a graphics editor and save it as a PICT file.
• If your preferences are configured to connect to a 411 Directory Server which is unavailable because you don't have access, the server is not running or the server already has the maximum number of connected users, you may receive an error -7974 on launch. If this happens, try launching again. To select another server, it is best to select the server in the preferences dialog, quit the application and relaunch. The 411 Directory Server at live.netscape.com is often busy.
Note: If your ISP assigns a different IP address every time you connect (dynamic addressing) you will need to notify parties of your current IP address before they can call you. Your IP address appears in your TCP/IP Control Panel. In some cases, the address may not update until you actually use an IP service, such as trying to place a CoolTalk call. The 411 Directory Server tries to alleviate the limitations of dynamic addressing. If available, static addressing is preferable.
• Apple VideoPhone Lite checks for an available TCP/IP network. Before you launch Apple VideoPhone Lite, you must configure and activate your TCP/IP Control Panel. If you have a direct Internet connection consult with your network administrator to make sure you have the correct IP address, subnet mask and domain name service information. If you are using a modem or ISDN terminal device, configure your TCP/IP to dial your Internet access account via PPP. Apple VideoPhone Lite will initiate the call on launch if PPP is configured correctly.
• Before you launch Apple VideoPhone Lite, it is recommended that you turn off Virtual Memory (VM) in the Memory Control Panel. VM is NOT recommended for use with any QuickTime application using real time video. On certain Macintosh computers you will not be able to send video unless you turn off virtual memory.
• You may notice that application memory isn't being released promptly after you quit Apple VideoPhone Lite. If this is a problem uncheck the "Load only when needed" checkbox in the options dialog in the TCP/IP Control Panel.
Connecting
• You must allow enough time for a complete disconnection before you try to connect again. Apple VideoPhone Lite currently requires several seconds to completely disconnect from a conference. If you try to connect (or someone tries to connect to you) before you have completely disconnected, you may experience problems. It is best to wait at least 10 seconds between connections.
• You may experience problems calling a person to whom you are already connected.
• Auto answer doesn't work with Apple VideoPhone Lite in the background and Movie Player running in Presentation mode.
• It is possible to access Netscape's 411 Directory Server from a web page. The URL is http://live.netscape.com/. The first time you use it, you will be asked by Navigator to pick an application to launch. Be sure to select Apple VideoPhone Lite. You will experience difficulty if you select the Conferencing Helper Application included with Apple VideoPhone Lite. For more information about the proper use of the Conferencing Helper Application, see below.
Audio
• If you are using CoolTalk settings to audio conference, and you see a dialog box notifying you that you don't have the correct type of audio compressors, you can download the audio compressor from Netscape's FTP site at:
• When conferencing with a CoolTalk user on a PC, you may find that you cannot hear audio sent by the PC. Some PC sound cards do not support full-duplex sound. Try clicking on the "Hold" button on the Mac side when you want to hear audio from the PC. This will temporarily block the Mac from sending sound. You will have to deselect "Hold" on the Mac when you want to talk. You can also try adjusting the silence sensor in the sound level meter. Asymmetric connections, where one computer is connected to a relatively fast network and the other computer is using a 28.8 modem connection may experience the same problem.
• Full-duplex audio is not supported on the Performa 6320. You will not be able to talk and listen at the same time.
Video
• When using the H.263 video compressor, you will not be able to resize your self-view window to the largest (2X) size.
• Apple VideoPhone Lite does not run well on multiple monitor configurations. For best results, arrange all Apple VideoPhone Lite video windows on the monitor that is connected to the AV subsystem of your computer.
•Apple VideoPhone Lite may not run properly in videoconferencing mode if launched when Apple Video Player is already running, or if the 1.0 extensions for the Avid Cinema Card are enabled. Quitting Apple Video Player and/or temporarily disabling the Avid Cinema extensions will enhance the video performance of Apple VideoPhone Lite.
Using Conferencing Helper Application
The Apple VideoPhone Lite installer places the Conferencing Helper Application inside a folder called "Extras" in the Apple VideoPhone Lite folder. The Conferencing Helper Application can be used to enable Apple VideoPhone Lite to be launched as a helper application from a web page. Netscape Navigator 2.0 or later is pre-configured to recognize the QuickTime™ Conferencing mime type. For instructions on how to configure other web browsers, consult the instructions on the QuickTime™ Conferencing Home Page. Additionally, it is recommended that you configure the Macintosh Easy Open control panel by disabling "Always show dialog box" and enabling "Auto pick if only one choice."

QuickTime™Conferencing and Firewalls
At those sites with Internet firewalls such as corporations, universities or other large institutions it may be necessary to configure the firewall so that QuickTime Conferencing applications can use certain features. This is typically not a problem for Internet Service Providers. Contact your network administrator to send the following information.
• To allow MovieTalk calls to be sent and received at an Internet site, allow outgoing and incoming TCP traffic on port 458.
• To allow MovieTalk media streams to flow outwards through the firewall, allow outgoing UDP traffic with static port 458 and with dynamic port values greater than or equal to 7000.
• To allow MovieTalk media streams to flow in through the firewall, allow incoming UDP traffic with static port 458 and with dynamic port values greater than or equal to 7000.
• To allow CoolTalk to access the 411 Directory Services, allow incoming TCP traffic on port 6499.
• To allow CoolTalk calls to be sent and received at an Internet site, permit outgoing and incoming TCP traffic on port 6500.
• To allow CoolTalk audio streams to flow in through the firewall, allow incoming UDP traffic with a static port of 13000.
