Mixing the audio source of phone application to another source

TheMSsForum.com: The Microsoft Software Forum

Hi,

We are currently investigating on how we can mix or replace the standard
audio source (microphone of the phone) of the standard phone application of
a Windows mobile device to another source.
The goal is to be able to send through the phone specific audio datas in
place of microphone inputs.

Does anyone know if there is an API that would allow sending a custom audio
stream from a Windows Mobile device to the phone line ?

I know that the phone API allow issuing a call, but it doesn't seem to allow
sending custom audio datas (i.e in place of or mixed with the standard
microphone), while a phone call is pending.

Thanks in advance
Y.Chamming's

While I am not an expert here I believe it can be done by getting the line
device with the TAPI lineGetID function, and the opening it up with the
waveInOpen function from the waveform apis ( Audio > Waveform Audio >
Waveform Audio Reference > Waveform Audio Functions ). Look for more docs on
this.

Myself I'm trying to do the same with video calls, however I am having no
luck on that front, seems not possible so far.

Thanks
I'll check the feasability of this. My point of concern is that I'm not sure
that during a phone call, we can access directly the modem (it is probably
driven directly from a DSP)
