My clients (Banking Industry) Cisco IP Phone has started to have this ' network unavailable' problem. They have been using this phone for more than a year and I'm afraid more phone will get this kind of problem (currently 3 IP Phone has this problem). I've tested the faulty phone by change the cable, IP address, change to other port, used DHCP or static IP but the phone still not working.
I suspect it's a hardware problem, maybe the network port are burnt. Have anyone encounter this kind of problem, please give your opinion and advice.
** I already full reset the phone too
Thank You.

It seems to be a big design mistake, I have a 7841 where the solder connections just peeled off the board. There is no resistance to mechanical stress applied to the network port. Make sure that is not your case. Thanks to everyone here, who referred me to this one. I will try to do some jumpers and save my phone. Just need to know where each pin should be connected.
