Project DescriptionManaged .NET library for interacting with the Microsoft Telephony API (TAPI) 2.x. This library is for creating clients that consume telephony services on Windows XP or better.
This project has been around a long time on
http://www.julmar.com in binary form, and I finally obtained the permission to release the full source to the project. It's very stable and has been used in all kinds of telephony related projects.
For a simple example, check out
