Probably a stupid and simple question but I didn't found an answer so far even searching for quite some time. How could one configure a call forwarding from the phone itself. Usually this is done on other systems by some dial code eg. *21 but I didn't found an equivalent way in 3CX yet. I know that I could setup the presence profiles. However, it should be possible to perform this simply and to any internal destination from the keyboard, eg. *2120 which forwards any call on the current extension to the extension 20.
