That's an interesting question... you don't have access to any admin level UCM accounts?
That's might be painful since UCM is essentially the trusted source in 6.0 and above although I believe it gets replaced with Aura System Manager in 7.5 and above (I could be wrong about that one).
I wouldn't try to mess around with this one myself, I would advise that you contact a reseller to try and figure out how to proceed.
Good Luck!
