FritzBox Fon WLAN 7270

Had the box now working for about 6 weeks. It is connected to BT Broadband and works fine as both a router and a telephone exchange. It does not connect to BT Broadband Talk VOIP although I have tried all the available settings and following advice from the Internet. Connected to several VOIP plans and using the custom settings to arrange to use BT for normal phone calls and calls to mobiles (cheaper). Issues I have with the Fritz.box: when using a handset the telephone options, answer phone options etc. are all in German!! This is frustrating and problematic but apparently something that will be fixed in a future update (when??). I am using Siemens Gigaset SL37H phones that work well with the box. WIFI is fast and reliable.
