The Iphone settings that you are seeing in the eyemax software are for a two way audio connection between the dvr and another computer. Not for the Apple iPhone. To use your eyemax system with the Apple iPhone, you must upgrade your dvr to one of the new Apple iPhone compatible devices. The newest version of the software, 5.5.0.0 might work for 9120's, 9240's, etc.. But you will need to enable web login on port 80 in the network settings in the eyemax software.
