DTMF detection

Ok. I've seen my mistake. The correct is to read dwEventData not dwData.

w2cUsbM_TranslateEventToString(wDeviceID, tmpStr, dwEventCode, dwEventData);

Anyway, I believe that the demo program's source would be a great help for people that dealing telephony devices for first time.

Hi to all.

I'm using the dll library and C++ Builder (2010) to control the usb modem.
By the way the API is very well developed and it's really a professional work. Respect.
The documentation could be better thought and it would be great if you publish the code for the w2cMultiTestApp.exe.

I have a problem regarding dtmf detection that derives from my code because the dtmf detection works well in  w2cMultiTestApp.exe. What I'm doing is that I' m switching the device to HPCMD_SW_PHONE_AudioStream mode and debug print all the incoming events. When I'm hooking off the phone whatever key I press I'm always getting a "DTMF: '0'  [Common]" event, that means that the dtmf detector always reports the same button. Probably it has to do with the gain or the detection time, I don't really know. On the other hand as I've said it works without problems with the demo application.

As I'm not familiar with all the aspects of telephony devices, are there any default rules that I've to follow in order to initialize the device properly? For example which are the parameters that I have always to set every time the software starts etc.

Finally, every time the software starts is always necessary to initialize the modem or it keeps its last configuration?

Once again I must mention that it would help a lot the developers if you publish the source code for the w2cMultiTestApp.exe. It has all the features and helps a lot to understand how the API works.

Thanks in advance for any answer.
