Hi. I am using the free version of 3CX. I was using calltriggercmd.exe (http://www.3cx.com/blog/docs/3cxphone-for-windows-api/) to dial a number from my own app. This week, without any changes or updates in both, I lost the ability to dial using calltriggercmd.exe. I was using "calltriggercmd.exe -cmd makecall:<number> but now nothing happens. I did not update or change anything but 3CX Phone System warned me that the free year of maintenance has ended and asked if I wanted to buy/renew it. What is wrong? Any ideas?
