I'm interested in building a CUCM lab. I know there are a bunch of threads on this, but need some guidance. I have vmware workstation and I know the OVA's can be installed on it, but that's the first question. I don't have the ability to get the software from Cisco. We don't use Cisco Voice at our office.. only data. I see on ebay you can purchase the software with the understanding about the limited license where you have to reinstall every 60 or 90 days. Is there anything specific I should watch out for when buying on there, or is there another avenue I can explore.
