7912G firmware upgrade from SIP to SCCP

Want to change firmware type for my 7912G. It is based on SIP image CP7912010301SIP050608A

Version 1.3.1(050608A)

Can I convert it to SCCP CP7912080004SCCP080108A.sbin which is the latest version?

Many thanks. I've spent more than 4 hours reading and testing p.bevilacqua advice, but no luck.

I tried to use a laptop as a tftp server and use a layer3 switch as tftp server. Here is the tftp debug from the layer3 switch:

Jul 14 18:06:43.705 AEST: TFTP: read request from host 172.22.1.91(16262) via Vlan250

Thanks in advance.

Re: 7912G firmware upgrade from SIP to SCCP

Hi,

your "gk" file must be wrong, how do you generated it ?

Re: 7912G firmware upgrade from SIP to SCCP

I read a lot useful information you've given.

1. download bmp2logo.zip from cisco web site

2. create txt file gk00141c48d472.txt:

{

#txt

upgradecode:3,0x601,0x0400,0x0100,192.172.22.1.90,69,0x080108A,CP7912080004SCCP080108A.sbin

192.172.22.1.90 is the ip address of the tftp server

}

3. C:\000>dir

C:\000>cfgfmt gk00141c48d472.txt gk00141c48d472

C:\000>

4. copy file gk00141c48d472 and

CP7912080004SCCP080108A.sbin to the tftp server.

5. power reset IP Phone 7912

Re: 7912G firmware upgrade from SIP to SCCP

I saw that. I have to wait another 48 hours to test that as I do not have PoE switch with me at the moment. Appreciate it.

I will update here after testing.

One more thing, when I tried this ont the 7912G, it looks nothing happened:

try the reset sequence: power off, press and hold #, power on, wait for led to flash in pattern, release #, press in sequence 123456789*0#.

Hi mate, the 7902/05/12 do not support any keypad reset sequence.

Thanks for the appreciation and good luck!

Re: 7912G firmware upgrade from SIP to SCCP

I bought the 7912G from ebay and it comes with SIP image. I would not buy it if I knew that. Should have asked the seller before click the button!!!

When I tried to disable the DHCP on 7912G, it ask me to input the password, is there anyway to reset the password?

Re: 7912G firmware upgrade from SIP to SCCP

No worries, just use a little bit of patience and the phone will do what you want.

The password is set via config file. Perhaps try something like 0000 or 1234.

Re: 7912G firmware upgrade from SIP to SCCP

Thanks a lot. I still do not have access to a PoE switch. I will update result here after the test.

Re: 7912G firmware upgrade from SIP to SCCP

The password is 1234. After fix the ip address, everything is working now. Thanks again.
