Hi experts,

I have been assigned a project that involves me to write some code in C# to dial through a voice modem and establish a hands free audio communication from my PC to a telephone line.

I am clueless with this project and I hope any of you could point me at the right direction.

Thanks in advance for your help!

Solution 2

I am looking for a PSTN (Analog modem) interface. Not VoIP. But these links do give me an idea on where to look for.

Is it true the TAPI 3.0 is not supported by C#?

Solution 3

hi Nikke
tapi was written as unmanaged and it is diffrent than c#
but many command can be converted by using their dll to your c#
it will consume programmer time if he/she decided to work alone
