/mcp• An SRTP-enabled HA setup requires distinct RmCm provider users. So, the system generates a separate RmCm Provider User Id with the suffix "_ccxsub" for the subscriber node. • Associate devices and device profiles only with the RmCm Provider User that is configured in the Cisco Unified CM Configuration page (primary RmCm user). • Agent desktops must be synchronized with NTP server so that the time in the auto incrementing fields of Live Data reports match the server time. • From Unified CCX Release 12.5(1), the 300 agent deployment model is not supported. Deployments that require more than 100 agents have to use the 400 agent OVA profile. The vRAM required for the 400 agent OVA profile has increased from 16GB to 20GB. Customers who want to use Cloud Connect services with the BE6000 must increase the vRAM from 10GB to 14GB. For information about Resource Requirements, refer to the Virtualization Wiki. • If FIPS must be enabled on 12.5(1) SU3, the CUCM version to be used is 14.0 SU3. This is because of change in the security provider used in the product. As the OVA profile is changed for 400 agent model deployments, if you do not change the OVA settings, the upgrade fails at Switch Version. For fresh install, the new OVA must be used for deployment. For more information, see Cisco Unified Contact Center Express Design Guide. Note Ensure that the reservation of CPU and memory adhere to the specification mentioned in the Virtualization Wiki. Caution • After upgrading Unified CCX, the CAs that are not approved by Cisco are removed from the platform trust store. However, you can add them back, if necessary. • For information about the list of CAs that Cisco supports, see Cisco Trusted External Root Bundle in https://www.cisco.com/security/pki. • For information about adding a certificate, see the procedure from step 5 onwards under the Obtain and Upload CA Certificate section in Cisco Unified Contact Center Express Administration and Operations Guide. • You can download the Chat Transcript in only HTML format. • You can configure the maximum number of concurrent sessions for a user of the following applications: Cisco Identity Service Management, Disaster Recovery System, Cisco Unified CCX Administration, Cisco Finesse Administration, Cisco Unified Serviceability, Cisco Unified CCX Serviceability, Cisco Unified OS Administration, and Cisco Unified Intelligence Center. If a user reaches the configured limit, further login attempts are rejected. The maximum number of concurrent sessions is configured by using the set webapp session maxlimit command. For more information about this command, see the Command Line Interface chapter in the Cisco Unified Contact Center Express Administration and Operations Guide at https://www.cisco.com/c/en/us/support/ customer-collaboration/unified-contact-center-express/products-maintenance-guides-list.html.
