The APP does not find a base in my network, why?

As the APP uses an internet connection to find all IP base stations in the network, this mechanism will fail in case no connection can be established. In this case the APP can be used in manual mode, only the IP address of the respective IP base has to be known. Easiest way to find it out: Start a paging call by shortly pressing the button on the base, the IP address is presented on all called handsets. Enter this address into the editor presented by the APP and fill in correct PIN, the connection will be established. The used IP address will be stored in the APP and is used for the next use without an internet connection.
