I've gone through much of the forums to try and bottom this out but can't find a clear answer. We are using full licence 3CX v11 and aren't especially demanding users. Our *one and only* method of transferring calls is to press one of 2 pre-programmed BLF buttons on our handset (SPA504G) which puts that call into SP0 or SP1 depending on which button is pressed. The button pressed turns red on all phones. The person who answer the call shouts to whomever should take the call, or sometimes will call a more distant extension and advise them that a caller is waiting on "red button 1 or 2". The person simply lifts the handset, presses the red BLF button and connects to the caller - very easy. We've used 3CX for 3 years and have not yet needed a third parking orbit, so the solution is good for us with the phones we have. Version 12 offers some nice new features, but I can't see anywhere whether this functionality still works properly? I did briefly test it with a temp v12 install on a different server. I was time pressed but saw that whilst the function worked, the BLF button did not change to red to indicate a call was parked. We have some staff with heavy technophobia :roll: and trying to make them change habits is hard work. Can v12 still do what v11 does now with a little extra tinkering of templates etc? I want the luddites to be able to use the system as if nothing changed, and the more adventurous 8| to enjoy the benefits of 3CXphone and mobility options. Thanks for any insight.
