Hello! I started to build automatic dialer with CFD and there was a question about logging at external script. I copied the code from the topic https://www.3cx.com/community/threads/find-amount-of-available-call-queue-agents.49551/ http://myprintscreen.com/s/rgn2/2d13dd2d69 And everything works as it should and thanks to the author for code However it is necessary to do additional logging at this code but I can not to do this. In file "3CXObjectModel.22.214.171.124_v15.chm" I found that PhoneSystem contains the necessary interface http://myprintscreen.com/s/rgn5/20dbe7cef8 I added a line of code to the FreeAgentsCount.CountFreeAgents PhoneSystem.Logger.Error("THISasdjasjlksdk182793 unique string for test"); I build the project, upload it, restart queue and it works at it should. But here in any messages at log files (i try to find at '3CXQueueManager.log' and other 3CX log files...) Please tell me how to log messages in external script and where are they stored? Thank you for your help and time.
