Question about Cisco 7912G IP Phone
We have several IP phones that are stuck at boot.
De red and green led continue to lit
Nothing in the display
Nothing happens at all.
This happing when trying to download a firmware upgrade or config from server and there is a power outgage.
Put a file called cp7912r.zup in your tftpserver root. This file can be a valid cisco image, for example, CP7912080001SIP060412A.sbin

I have had the same issue with several handsets returned to me. There was DHCP activity, but the handsets never requested a file - most sites have suggested you must specify option 150 in the DHCP settings and not 66 but I eventually tried 66 and hey presto - the phone requested the 'cp7912r.zup' file.

So after encountering this exact problem on nearly 10 separate
phones I inevitably found this thread. While alot of the information
definitely helped me to find the solution, there is a few things that
HyperTerminal or Procomm will allow you to see the boot procedure/sequence. I was continually getting stuck at the DHCP response. You will also need TFTPD32, and have it set up per these instructions : http://www.planex.net/pdf/switch/sw-0208g_setup_eng.pdf
Norksman's Factory reset code is one of the reset codes, the other one that took some digging to find was this one:
With all the proper files in place, TFTPD32 setup properly, Procomm to watch it's status, and this reset code, you should be up and running!
If not, you are more than welcome to send your phone to http://IdacomUSA.com and I would be glad to help ya out!
