Table 3-1 Critical Services to Monitor Service Stop | Start| Restart Instruction Process Auto Name Restart Description Cisco CallManager Serviceability/Tools > ccm 3 Control Center - Feature Services ***** The Cisco CallManager service provides software-only call processing as well as signaling and call control functionality for Cisco Unified Communications Manager. Cisco TFTP Serviceability/Tools > ctftp 3 Control Center - Feature Services ***** The Cisco Trivial File Transfer Protocol (TFTP) builds and serves files that are consistent with the trivial file transfer protocol, a simplified version of FTP. Cisco TFTP serves embedded component executable, ringer files, and device configuration files. Cisco IP Voice Serviceability/Tools > ipvmsd 3 Media Streaming Control Center - Feature App Services ***** The Cisco IP Voice Media Streaming Application service provides voice media streaming functionality for the Cisco Unified CallManager for use with MTP, conferencing, music on hold (MOH), and annunciator. The Cisco IP Voice Media Streaming Application relays messages from the Cisco Unified CallManager to the IP voice media streaming driver, which handles RTP streaming. Cisco CTIManager Serviceability/Tools > CTI 3 Control Center - Feature Manager Services ***** The CTI Manager contains the CTI components that interface with applications. With CTI Manager, applications can access resources and functionality of all Cisco Unified CallManagers in the cluster and have improved failover capability. Although one or more CTI Managers can be active in a cluster, only one CTI Manager can exist on an individual server. An application (JTAPI/TAPI) can have simultaneous connections to multiple CTI Managers; however, an application can only use one connection at a time to open a device with media termination.
