[edit] Converting a Cisco 7940G IP phone SCCP 8.x to SIP 8.x image
Set up a TFTP server on your box (192.168.1.1), put all these files in the TFTP root directory.
• dialplan.xml
• OS79XX.TXT
• P0S3-08-2-00.zip
• ringer1.pcm
• ringer2.pcm
• RINGLIST.DAT
• SIPDefault.cnf
• SIP{MAC}.cnf
• syncinfo.xml
• xmlDefault.CNF.xml
Uncompress P0S3-08-2-00.zip file.
SIP{MAC}.cnf must be filled with the MAC address present on the IP phone.
In OS79XX.TXT file, ensure that the application loader is the same as the name of the ZIP file.
You must find: P003-08-2-00
In SIPDefault.cnf, check that the image filename is correct:
# Image Version
image_version: "P0S3-08-2-00"
and proxy address (IP address of your TFTP server) :
proxy1_address: "192.168.1.1"
In SIP{MAC}.cnf, here are the minimal modifications required to have a functionnal IP phone :
line1_name: "100" (extension number)
line1_displayname: "pello"
phone_label: "pello" (no effect on SIP messaging, it's just a displayed text on the phone)
phone_password: "cisco"
In syncinfo.xml, check the image version :
<SYNCINFO>
<IMAGE VERSION="*" SYNC="1"/>
<IMAGE VERSION="P0S3-08-2-00 SYNC="1"/>
</SYNCINFO>
In xmlDefault.CNF.xml, check the loadinformation7 and 8 models :
<loadInformation8 model="IP Phone 7940">P003-08-2-00</loadInformation8>
<loadInformation7 model="IP Phone 7960">P003-08-2-00</loadInformation7>
Files modifications are complete.
Now the conversion.
Plug the IP phone and your box (TFTP server) with a crossover cable.
Start the IP phone. Wait the phone for booting.
Unlock the IP phone with unlock soft button (last command of the list) in the settings menu.
Always in settings menu, go in menu 3 : network configuration
Go to option 30: specify NO with DHCP enabled
Go to option 6: specify 192.168.1.X/24 address in IP address
Go to option 7: specify 255.255.255.0 in subnet mask
Go to option 8: specify 192.168.1.1 for the TFTP server address
Go to option 9: specify 192.168.1.1 for the default router address
Press '''"Save"''' soft button.
The phone is rebooting. At the next boot, you will see SIP logo in top of the right.
