39. Updates - Details

40. Cisco Unified Communications Manager 8.5
Call Processing Capacity
There has been an overall increase in the Unified Communications Manager (Unified CM) call processing capacity across all call types. Calls for certain protocols are improved substantially:
SCCP to SCCP Calls in detailed tracing mode show an improvement of 15%. In default tracing mode, the improvement is marginal.
SIP to SIP Calls in detailed tracing mode show an improvement of 22%. In default tracing mode, the improvement is 10%.
SIP to H.323, SIP to MGCP, SCCP to H.323, SCCP to MGCP all show an improvement of between 15 to 20%.
Constants
Server and cluster limits such as those for Phones, Cluster Size, CTI, Locations, Regions, Number of Gateways, etc., are unchanged.
Memory Usage
Overall memory usage for a typical system deployment is expected to be comparable to the 8.0(3) release. In particular:
Memory required for the configuration and registration of a single line unsecure SCCP Phone has increased by 18%, and for single line secure SCCP phones by 12%. Extra memory required for adding additional lines in SCCP phones has decreased by about 16%.
Memory required for the configuration and registration of a single line for unsecure SIP phones increases by 11%, and for secure SIP phones by 10%. Extra memory required for adding additional lines in SIP phones has increased by about 100%.
Memory required for other configurations and overheads such as that for CTI, Partitions, Calling Search Spaces, Translation Patterns, Route Patterns, etc., are all unchanged.
Memory required for calls placed between two SCCP endpoints is reduced by 18%.
Memory required for calls placed between two SIP endpoints remains unchanged.
Memory required for calls between SCCP and any other protocol is reduced between 10-15%.
Memory required for calls between SIP and any other protocol remains unchanged.
Server Performance
The VM - CUCM_7500 is equivalent in performance to using MCS-7845-I2/MCS-7845-H2 servers. The VM - CUCM_2500 is equivalent to using MCS-7835-I3/MCS-7835-H3 servers. The VM - CUCM_1000 is equivalent to MCS-7825-I5 servers.

41. Cisco Unified Contact Center Enterprise 8.5
Maximum Capacity Increase
Maximum number of local agents supported on high end servers has been increased from 1000 to 1500, provided the deployment uses Unified CVP. Note that the real number of agents that may be supported depends on other traffic and activities in the system.
VM Platform Performance
The SIP call capacity and number of ports supported on the VM-based Unified CVP Call Server has been reduced by about 25%.
New Features
Sizing for two new features in 8.5(1) will be added: Agent Greeting and Whisper Announcement. A call with Agent Greeting enabled is equivalent to two calls with it disabled. That is, call handling capacity, in calls per second, is cut in half if Agent Greeting is enabled for all calls.

42. Cisco Unified Contact Center Express 8.5
Performance factors for Unified Contact Center Express (Unified CCX) Release 8.0 and earlier features remains unchanged.
