I am working on a project to upgrade ccm 4.1(3) to ccm 5.1(2)
How do i sort out the issues of licensing. I have 3 Callmanager servers in my cluster. The phones were purchased with licenses when we bought them.
Secondly, Can I edit the LMHOST file in ccm 5.1... If I cant do this, how do I add MGCP gateways names and IP without using a DNS server....
