Hi! I have unactivated&unused LIC-CM-DL-500= PAK that was bought for CUCM 6.1. The CUCM 6.1 was changed by CUCM 8.0.(3a). I know that this version is still in fact based on DLUs and I want to use those DLUs on CUCM 8.0(3a). Can I do that? My CUCM is installed on VMware so what MAC-address do I use to register DLUs? Is it a hardware address or license MAC?
