You have to upgrade to a new version of SCCP or older version of SIP
before the bootloader on the phone will be able to handle the newer
firmware.  In the same Cisco page you read the info is there - you can
either use an older version of SIP first, or a newer version of SCCP..
Older SIP is probably easier - 6.3 is the newest you can use to then
jump to 7.x and/or 8.x..

You will need to put this in SEPDefault.cnf (not SIPDefault)

image_version:P0S3-07-5-00  (whatever version you grab)

That will tell it to grab the SIP firmware if it is not using OS79XX.txt
- I cant remember that far back if it is still used..  Doesn't hurt to
have both though...
