Nothing I can think of. SMDR reports come to mind for any after-hours (working from home), but assumes you have an SMDR package.
If you purchased CUWL license bundles, you ought to have enough DLUs, assuming you followed the rules and went 1 for 1, hardphone vs softphone. However, if you purchased CUWL license bundles but then leveraged the bucket of extra DLUs to deploy more hardphones than you bought licenses for, as some do, then it's time to true-up and pay the piper. Either way I see a check being written, which is quite possible of happening sometime in the near future anyway, as I keep hearing rumblings of a revised licensing structure coming in CUCM 9.x that will force customers to true-up.
From the ACUCW2 (8.0) training course workbook vol. 2: "CUWL leverages existing license enforcement mechanisms. In future, (sic) products will become "CUWL aware." Additional enforcement will happen. If you fail to comply with the rules, you will be impacted."
