I have not had any emails telling me it is disconnected since I setup my static ip. Also the phone has worked since then, other than I get a lot of words cut off.
It looks like the problem may be my internet then. My internet has never been real good, because I am away from any large city, and so there is no hard wired internet, it is all wireless. However it used to work fine with the phone until I switched to the "faster" service, which does work better for streaming video, but maybe it is worse for voip.
Although I did have to run this test within a virtual machine, since I am running linux, and the software is for windows, or mac. I am not sure if that has anything to do with it.
