I have 3cx v12 installed - 64SC Standard. I have 3cx Phone for Windows installed. It is working in CTI mode with my Yealink T46. In Chrome, phone numbers are now tel:// links. I click on one. A command box pops up and goes away. Nothing happens. In my registry, tel is linked to Code: C:\ProgramData\3CXPhone for Windows\PhoneApp\CallTriggerCmd.exe -cmd makecall:"%1" Should this be working? Even typing this in manually into a Command Prompt does nothing.
