Hi, I have EL71 prototype. It has one interesting bug, that makes phone unusuable - typical siemens dialing tone (before it starts ring) is done very,very loud. And ringing tone very often also loud, not allways . I can not use phone for normal calling, because everyone is looking at me "what the hell are you doing" - I spent hours looking in phone menu, including developer menu and have not find any way to change it. It is doing on any fw version I use. Is here anybody who can help me?
