You can use it for Unity but NOT for CCM. Anyway we have patches for both:
On the Call Manager side we have two DDTS for this issue:
CSCsf07541 - MCS-OS Update needed for N America DST changes in 2007
CSCsf07523 - Update needed for N America DST changes in 2007
You can view these defects at the following link below:
http://www.cisco.com/cgi-bin/Support/Bugtool/home.pl
For the first one you need either 2000.4.2 sr14 (for this train) or 2000-4-3a-sr8 or later (for this train) or 2000.4.4sr2 and later (for this train).
For the second one you will find the fixes on the following Engineering Specials (or later):
- 3.3(5)ES56
- 4.1(3)ES89.1
- 4.2(1)ES38
- 4.2(3)ES11.1
All the other versions of CallManager will not have this bug fix.
Another option for customers that do not wish to apply an Egineering Special is an individual DST patch:

http://www.cisco.com/cgi-bin/tablebuild.pl/callmgr-41
http://www.cisco.com/cgi-bin/tablebuild.pl/callmgr-42
But to be fully patch you need both the OS and the CCM upgrade.
For Unity you need the following patch:
