Hi,

I have Cisco 7960 ip phone, i have connected that in a PoE port, the phone doesn't boot, so what i use to do is, i use a power adaptor, then the ip phone bootz after the ip phone is booted completely, i remove the power adaptor, the ip phone functionz normally, this practice i am doing it when ever i switch OFF & switch ON the ip phone. I also tried connecting to the existing working IP phonez which doesn't even require a power adaptor for booting. those phones works perfectly, i tired replacing with this ip phone on that, the problem is same.
