Dear Sir, Sorry to write in English, but my German is about zero. I bought a FB 7170 from ebay.de, which was successfully upgraded to the latest ENGLISH firmware (29.04.57). All function working now in order (ADSL modem, router, Wlan, outgoing calls on VOIP and analog line, call directions) expect the ringing on incoming calls (not for VOIP and neither PSTN). I use the original Y cable for ADSL/ tel. line input (1-8 pins at the end of tel. cable) which must be good. I use only one analog phone on line 1. (I have heard 2 times a very little (0,2 sec?)irregular ring from the phone, but not for an incoming call.) I can see the incoming calls on the leds (on FB), and can speak and hear the other side. Settings: > extensions: React to all numbers, no night service, etc. I have overlooked the setting 100 times, and I can't find any fault. I am very helpless now. Can anybody help me what to do and what is wrong?
