Hi, i did a Factory Reset to my UC520 System and using the CCA 2.2 then i try to configure the Call Blast Groups under Phone Groups but this option is not  showed up. Do you know why? The reason for the factory reset was that originally i configured the UC520 as PBX system but we have the need to incoming calls ring at the same time in all users extensions and in some documentation i read that is only possible if i configure like KEY System.
