As Figure 5-3shows, a Cisco IP Telephony Solution system has these main components:

•Gateway—Connects the enterprise IP telephony network to the PSTN and to other private telephone systems, such as a PBX. In the Cisco ICS 7750, the MRP provides the gateway function.

•Cisco CallManager server—Provides the features for the IP phones, manages gateways, provides failover and redundancy service for the telephony system, and directs VoIP traffic to the CRA system. In the Cisco ICS 7750, the Cisco CallManager server runs on an SPE.

•Cisco IP Telephony Directory—Stores configuration information and CRA application scripts in an LDAP directory. The subdirectory that stores CRA scripts is called the Repository. Storing application scripts and configuration information in an LDAP directory allows loading application scripts on any CRA server in the network. The Repository keeps one backup version of each script for recovery purposes.
