IME you cant go straight to version 8 of the SIP image from SCCP. I have
done over 200 conversions of this phone and have always had to go
through the following process.

SCCP -> SIPv4 -> SIPv6 -> SIPv7 -> SIPv8

Any attempt to miss out one of these steps have failed. Its a right
royal pain in the ass.

Are you setting the TFTP server address in option 66 in DHCP?

Have you set the firmware level in OS97XX.txt and SIPDefault.cnf

Are you checking the TFTP server logs to see if the phone is requesting
the files and is trying to serve from the right location.

Well the firmware I have seems to have slightly different filenames

P0S3-08-4-00.loads
P0S3-08-4-00.sb2
P003-08-4-00.bin
P003-08-4-00.sbn
