Hi, We are about to switch 3CX from version 12.5 into 15.5. We have some code developed using 3CX Phone API. Before we switch, we need to have a documentation for version 15.5 of 3CX Phone API. Where can I find it? https://www.3cx.com/blog/docs/3cxphone-for-windows-api/ has an example for version 14, is it valid for version 15.5?
