A typical deployment architecture is shown. A router regulates traffic between the Oracle Beehive cluster and the Cisco Call Manager cluster, as well as routing traffic to IP telephones. An additional router sits between the Cisco Call Manager Cluster and the PSTN. Direct communication also occurs between the Oracle Beehive Cluster and the Cisco Manager Cluster, and the IP phones. Various protocols (HTTP, RTP, and SIP) are used, some for the GUI and some for the TUI.
