Call Load Testing
This topic provides an overview of the call loads that were tested with various site models during Cisco Unified Communications Release 6.0(1) testing for IP telephony. It includes information for calls made within various site models (intracluster) and for calls made between site models (intercluster). During call load testing, the busy hour call attempt (BHCA) rates described in this topic were sustained for five consecutive days.
NoteThe information in this topic represents tested call rates, not the maximum call rate capabilities of the system. Also, call load testing was performed with all components configured with default trace/debug levels.

Very Large Campus with Clustering over the WAN (SJC-RFD) Load Testing
This section describes call load testing for calls originating or terminating in the San Jose (SJC) site or the Rockford (RFD) site in the Very Large Campus with Clustering over the WAN site model. The BHCA grand total tested for the SJC-RFD cluster was 83,623 busy hour call attempts. Table 1 shows the BHCA for various call types and call scenarios between different endpoints. In addition to the call scenarios shown, the Cisco Unified Presence Server in the SJC-RFD cluster maintained 1,000 active logins from Cisco IP Phone Messenger clients and monitored 1,000 user presence states.
