I am confused about how to set up the new feature in 12.5 to "Automatically transfer call back to blind transfer-er when destination is busy". I can see the settings in Settings->General->Global Settings, and I have read the admin guide, but still confused. I expected to see a tick box to enable/disable this feature globally. All I see is a unique dialcode (which I have set), and a time to wait for destination to answer before calling back (which I have also set). But I can't find any instructions on actually how to use the feature. What is the dialcode for? Does this mean I use the dialcode on an extension to turn the feature on/off? If so, why not make it an extension property? Does it mean we have to use the dialcode every time we make a blind transfer? If so, why not make it a right-click option in 3cxPhone? I want to make this feature mandatory for all extensions. This is a fundamental part of our client service. We do not have a receptionist (so calls can be answered by anybody in the office). We do not wish to pass customers to voice-mail, as in most cases somebody else can help if the original person is not available. Hence the new feature is very important to us, and we have been hanging out for it. I don't want staff to be able to decide whether they want to use the feature or not, or to be able to switch it off for their extension. Some advice would be appreciated.
