AddTapi.NET 6.0 has been redesigned to be fully compatible with .NET 6.0 and newer versions of the .NET framework. AddTapi now supports all major versions of .NET from 2.0 to 7.0. We provide separate DLLs for .NET 2.0-3.5, .NET 4.0-4.8 and .NET 6.0-7.0. Please note that AddTapi.NET is still a Windows-only library because it uses Windows-specific Telephony API.
