Use the module to connect an intercom system and an analog telephone to a Fritz box 7390. After half a day of wild orgies configuration and firmware update now everything works as it should :-). Looking for people who a plug and play solution is not recommended, the device, the connection as an IP phone to the network via FitzBox had indeed done it took in 2min to configure the analog phone lines the longer. I could not imagine until then that there are perceived 1000000 parameters which can be changed to an analog telephone line. Factory all is probably set to the American standard and the change to the German standard designed to any difficult :-(. The correct settings there only on Google somewhere on the net and not the manufacturer. If everything is set correctly, the device works well but and bit long and very reliable :-)
