The difference between xc software and non xc software is that with xc you can install a second 6 port fiber card to have all 12 port ability. Also just to second the CLID question, you can only see the caller id before answering on one phone with that software release. You can program a view button on all the phones though if people want to see the CLID info before answering or you can always upgrade to 6.1 and up.
