Hi,
Sorry, but if you are using the IVR property, "recordcall" in your IVR application, the call recording will always be posted as an 8000 Hz ulaw-encoded mono file.
As for your question about finding a suitable .NET converter for this type of file, we wouldn't be able to suggest a possible solution for you as we lack an expert developer who's worked with .NET and since we mainly use PHP. Perhaps another developer who's used .NET can assist?
Regards,
