my boss gave me a compact flash card which is IP4WW-CFVMS-C1, and ask me to test whether it is good or not.

I am not sure how to test it. First, I used a card reader, but can't read it out. I think the format is mismatched.
Then I found a SL1100 with exactly the same card, so I put it into the system, it didn't work, too.
And last, I got a inmail card PZ-VM21, put them into a SV8100, enbled 10-day temporary licence, and programmed the system as the manual says, but I just get busy tone when I dial pilot number of voicemail.

How could I know whether the flash card is working or not?
