What version IOS for the 6500 for CCIE Voice lab?

[jeffrey.girard]

The CCIE Voice Blueprint indicates that the 6503 uses "Switch OS version 7.6x"

Since the current version of IOS is 12.4, is this really accurate?

Im trying to focus my studies and want to focus on the correct Supe with the correct IOS

The 6500 in the lab runs CATOS and the routers run IOS, hence the reason for the discrepancy.

HTH

Thanks,
