Cisco CallManager Services

This chapter provides overview information about Cisco CallManager services.

The Cisco CallManager system comprises hardware and software modules. The software modules comprise services. Cisco CallManager Serviceability monitors the services to determine the status of the system. If something is wrong with a service, an alarm gets written to an alarm monitor. After viewing this alarm information, a system administrator can run a trace on the service. Obtain further details through analysis tools such as Trace Analysis or Bulk Trace Analysis.

The tools that monitor Cisco CallManager services include Real-Time Monitoring, Microsoft Performance, and any application written using the Cisco SNMP interface.

The following sections briefly describe the Cisco CallManager services that Serviceability monitors:

•Cisco CallManager Service

•Cisco Extended Functions Service

•Cisco CDR Insert Service

•Cisco TFTP

•Cisco Database Layer Monitor Service

•Cisco Messaging Interface Service

•Cisco IP Voice Media Streaming Application Service

•Cisco Telephony Call Dispatcher Service

•Cisco CTIManager Service

•Cisco MOH Audio Translator Service

•Cisco RIS Data Collector

Cisco CallManager Service

The Cisco CallManager service runs on the Cisco IP Telephony Applications Server to provide software-only call processing as well as signaling and call control functionality. You install the Cisco CallManager service from the Cisco CallManager CD.

Cisco Extended Functions Service

The Cisco Extended Functions NT service provides support for some Cisco CallManager features, including Cisco Call Back and Quality Report Tool (QRT). For more information about individual features, refer to the Cisco CallManager System Guide and the Cisco IP Phone Administration Guide for Cisco CallManager.

Cisco CDR Insert Service

When you enable call detail record (CDR) collection, Cisco CallManager writes CDRs to flat files on the subscriber databases as calls are made. The Cisco CDR Insert service periodically inserts the records from these files into the publisher centralized SQL database. The Cisco CDR Insert service does not insert a record if the CDR Format enterprise parameter has a value of Flat. For more information on CDRs and related parameters, refer to the Cisco CallManager System Guide.

Cisco TFTP

Cisco Trivial File Transfer Protocol (TFTP) builds and serves files consistent with the trivial file transfer protocol, a simplified version of FTP. Cisco TFTP serves embedded component executable, ringer files, and device configuration files.

A configuration file includes a list of Cisco CallManagers to which devices (telephones and gateways) make connections. When a device boots, the component queries a Dynamic Host Configuration Protocol (DHCP) server for its network configuration information. The DHCP server responds with an IP address for the device, a subnet mask, a default gateway, a Domain Name System (DNS) server address, and a TFTP server name or address.

The device requests a configuration file from the TFTP server. The configuration file contains a list of Cisco CallManagers and the TCP port through which the device connects to those Cisco CallManagers.

Cisco Database Layer Monitor Service

The Cisco Database Layer Monitor service monitors aspects of the database layer as well as call detail records (CDR). The database layer comprises a set of dynamic link libraries (DLL) that provide a common access point for applications that need to access the database to add, retrieve, and change data. The Cisco Database Layer Monitor service performs functions such as determining whether the primary server is available during failover, deleting the oldest CDRs when the limit defined in the MaxCDRecords parameter is reached, and moving CDRs from a subscriber to the primary database at a given interval, if needed.

Cisco Messaging Interface Service

The Cisco Messaging Interface allows you to connect a simplified message desk interface (SMDI)-compliant external voice-mail system with the Cisco CallManager. The CMI service provides the communication between the voice-mail system and Cisco CallManager. The SMDI defines a way for a phone system to provide a voice-mail system with the information needed to intelligently process incoming calls.

Cisco IP Voice Media Streaming Application Service

The Cisco IP Voice Media Streaming Application provides voice media streaming functionality for the Cisco CallManager for use with MTP, conferencing, and music on hold (MOH). The Cisco IP Voice Media Streaming Application relays messages from the Cisco CallManager to the IP voice media streaming driver. The driver handles the RTP streaming. The MTP and conference bridge components of the Cisco IP Voice Media Streaming Application support G.711 mu-law and a-law codecs. The MOH component supports G.711 mu-law/a-law, G.729a, and wideband codecs.

Cisco Telephony Call Dispatcher Service

Telephony Call Dispatcher (TCD) service provides centralized services for Cisco WebAttendant and Attendant Console clients and pilot points. For Cisco WebAttendant and Attendant Console clients, TCD provides call control functionality, line state information for any accessible line within the Cisco CallManager domain, and caching of directory information. For pilot points, TCD provides automatic redirection to directory numbers listed in hunt groups and failover during a Cisco CallManager failure.

Cisco CTIManager Service

The CTI Manager contains the CTI components that interface with applications. With CTI Manager, applications have access to resources and functionality of all Cisco CallManagers in the cluster and have improved failover capability. One or more CTI Managers can be active in a cluster, but 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.

Cisco MOH Audio Translator Service

The Cisco MOH Audio Translator service converts audio source files into various codecs, so they can be used by the MOH feature. When you install the Cisco IP Voice Media Streaming Application service, Cisco CallManager automatically installs this service.

Cisco RIS Data Collector

The Real-time Information Server (RIS) maintains real-time Cisco CallManager information and provides an interface through which the Cisco RIS Data Collector service and the SNMP Agent retrieve that information. One RIS exists on each node containing the Cisco CallManager service. The Cisco RIS Data Collector service provides an interface for applications, such as Cisco CallManager Serviceability and the Cisco CallManager Administration, to retrieve information stored in all RIS nodes in the cluster.
