UCCX Enhanced does not include the Advanced IVR license and therefore, IVR ports are not licensed. The install will be limited to the platform limits. On a 7845 this is up to 300 ports depending on design and features implemented.

Please reference the SRND for additional details.

Also, the Configuration and Ordering Tool is required when designing a UCCX deployment as part of the A2Q process. This may require a partner-level CCO account to access: http://www.cisco.com/en/US/prod/collateral/voicesw/custcosw/ps5693/ps1846/CRS_Config_Order_Tool_for_CCE_6.xls
