You can even develop your own plugin with the 3CX Visual Studio Template.


The 3CX Windows API is available for customers and developers (who have purchased the Pro or Enterprise Edition License) to use to integrate their applications with the 3CX softphone app. The API allows for such functions as launching calls from the application, receive notifications about call status and more.
