I was happy to see 'Change Status' as a new function in the BLF setup area for extensions in latest versions of 3CX. But, there are a lot more that the Yealink phones can support, such as 'Prefix'. It would be nice if more (maybe all?) of the functions that can be programmed in a Yealink phone could be made available in the BLF setup area in 3CX. For example, the 'Prefix' functionality is great. This allows a button to be programmed for "Intercom", which simply generates the *9, so that the phone user can press this "Intercom" button, followed by either the extension number or even a BLF button that has been programmed with the extensions in the system. Thus, the user doesn't have to remember the *9 code. But, that function isn't available in the BLF setup in 3CX for extensions. So, I have to leave the desired key 'Blank' and then program the desired key in the phone through the phone's web interface. The problem is that if I have to reprovision the phone for anything else, then that key is set back to 'blank'. Then I have to program it again directly in the phone. This is not good, if the system has a lot of phones. Of course, I could modify the template in 3CX, but that should usually be a 'last resort', if 3CX doesn't include something that we need in the phone. John Rayfield, Jr.
