Dear Bruce,
1. How do I play or record a .WAV file over the phone?
TAPI relies on the Windows low-level multimedia (wave) API
to play and record audio files. Briefly, the TAPI
application should call lineGetID with a device ID
of "wave/out" to obtain the ID of the wave device
associated with the telephony hardware. This ID that is
returned is then used to call waveOutOpen, etc. Similarly,
to record a call, call lineGetID with "wave/in" as the
device ID, then use the returned ID to call waveInOpen,
etc.
The aboce is the question and answer of the same
from our FAQ. You have mentioned that Waveform Audio is
better than MCI but I have tried not less than 100 times
to play and record the .wav files using Waveform Audio but
the result was negative. Then I have made use of MCI, now
I am able to play and record the .wav files using
microphone and speakers but how to perform the same task
over phone using MCI? I have put up my question in
multimedia and tapi newsgroups with the subject MCI query
but have not got any answer yet. So please guide me, how
could I send output to and received input from phone using
MCI.
