i have integrated tapi and sapi to make an interactive voice response system.
my application is somewhat similar to answering machine where i present a menu which user can select several options.
i have used tapi to answer calls and then using sapi functions i play the voice over phone line.
1) getAudioOutputs - to obtain all the wave outputs devices
2) AudioOuput - to set the wave output device as modem.
now the problem i face is that the voice which i hear is very low. Although the clearity is good.
is there any way u can guide me ???
