I'm looking into adding a CUCM Subscriber into our cluster as a virtual machine in VMWare ESX 4. I have two questions.
1. Is it okay to have a couple of physical CUCM's and add a virtual subscriber to that cluster?
2. How does the licensing work for that? Is there just a CUCM software part number for ESX installs? If so, what is the part number?
No. UCM 8.x will only be supported on Cisco UCS hardware. Third-party host support is a ways off.
Since we do not support anything other than CUCM 8.0(2) in VMWare we do not sell anything associated to this scenario.
You would need to buy any associated PNs as if it was a regular MCS install.
The only thing before 8.0(2) we support on VMWare are the NFR kits.
If this helps, please rate
Virtualization is only supported with CUCM 8.x and only on Cisco UCS servers. It is possible to install CUCM in a VM outside of these parameters, but it will not be supported by Cisco.
Hope this helps.
