Note VOICEPROF_SET_BAUD_BEFORE_WAVE 0x00080000
This bit indicates the DTE should adjust the baud rate before issuing the StartPlay/StartRecord commands. If the bit is disabled or cleared, then the baud rate will be adjusted after these commands are issued. Usually this bit is set for Rockwell chipset modems.
Distinctive Ring is not supported by Windows 2000 and later versions, therefore the bit value of 0x00001000 is required.
The VoiceProfile bit (0x02000000) is for Windows 2000 and later versions of the operating system. This bit must also be used in conjunction with the following voice entries that are specific to Windows 2000 and later versions of the operating system:
