which indicates that I require the firmware version for cisco unified communication manager 6.1
8.0(7) - SCCP
8.0(8) - SCCP
8.0(9) - SCCP
how can I find out what firmware version is "P00308000400" on my existing call manager 4.2?

Once you are satisfied with the new version you can change it for the remaining phones via Device Defaults (just a thought :)
