Hey, If you have an Internet access through that line so you need just to plug your phone then find out what ip address it uses.. From your browser use that IP address to access to the web administration page.
Assuming the phone set is still connected to the network, press the setup button, then press 9 to go into the Network setup menu. Then press 7 to choose whether to enable the phone's web server--it should say Yes if you want to use the web setup utility.
Then see if you can connect to the web setup page using the phones IP address in your browser.
I know what you mean about setup being tricky--I have the info from our VOIP provider to point the phone at the provider, but nothing I've found so far in the Cisco docs for this phone to say how/where to enter the parameters.
