The only requirement for the Speaker Phone feature is that a FULL DUPLEX sound card is installed and operating correctly. To test if your sound card operates in FULL DUPLEX you need to record a Wave file while playing a Wave file. You can use the Media Player to play a wave file and use the Sound Recorder to try to record the wave file that is being played. If you get an error message stating that the device is busy, YOU DO NOT HAVE A FULL DUPLEX SOUND CARD or the FULL DUPLEX driver is NOT installed properly.
