can the library used in Microsoft .NET environment

Dear team, 

Kindly feedback if the Chan-dongle library can be used in Microsoft .NET 
environment. are there any Windows based application that can test the 
capability of the Chan-dongle library.?

one more issue, i face and I am getting crazy regarding this issue :(.

I have an Huawei 3G modem K3765 which supports voice communications. My 
application in .net will be answering machine , ie if any mobile phone call the 
Huawei USB modem number, the program will open the  line and record the message 
from the caller mobile phone.If user click any key of the mobile phone keypad , 
the DTMF signal is  also recorded into the application and and can be played  
back for DTMF detection.
Program was working great for last 5 months. However, now the  recorded 
messages contains all sounds except the DTMF tone. ie, if the caller sound 
looks very clear , but when he pushes any key of the mobile phone , the 
generated tone is not recorded, and so I can not get the key that was pushed.
I have made phone to phone call using the same phone device , and pushed some 
keys , and I heard the tones on the other phone..

for me , now it seems that the Huawei K3765 usb modem remove the dtmf tone only 
, after it was working for months before. is this logic.
Please advice....

Thanks & Kind regards,
Waleed
