I found this too:
Unified Attendant Console Advanced Edition uses Single Server licensing (Publisher server will be responsible for all the licensing and customers are not required to license the subscriber separately). Cisco Unified Attendant Console – Standard, like the server based version is not supported by HLM or Prime License Manager. The administrator must obtain licenses for the Attendant Console and then enter the registration codes on each of the Attendant Console PCs and finally, enter the license activation codes from the fulfilled order. In the case of SMB, the consolidated license file feature may be useful to apply to each Attendant Console.
Again this concludes that we can use CUAC Stadard edition.
