I'm in trouble with my "Cisco IP Phone 7906G". This is the first time i have one of those things in my hands (and in my office). I have another ip phone configured on the network, of course its not a cisco one. My problem is. I have mo idea how to conf it, because on the phone "osd" I have no rights to change the important options.
Of course i havent got a user manual/handbook, or whatever.
So what do i need, or how can i make this phone work?
