The Cisco CallManager is the software-based call-processing component of the Cisco IP telephony solution. The software extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional data, voice, and video services such as unified messaging, multimedia conferencing, collaborative centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco CallManager’s open telephony application programming interface (API).

The Cisco CallManager software product includes a suite of integrated voice applications that performs voice conferencing and manual attendant console functions. The salient benefit of all these voice applications is that specialpurpose voice processing hardware is not required. Supplementary and enhanced services such as hold, transfer, forward, conference, multiple line appearances, automatic route selection, speed dial, last-number redial, and other features are extended to IP phones and gateways. Because it is a software application, enhancing ist capabilities in production environments is a matter of upgrading software on the server platform, thereby avoiding expensive hardware upgrade costs.

Further, Cisco CallManager and all phones, gateways, and applications may be distributed across an IP network, providing a distributed, virtual telephony network. The benefit of this architecture is improved system availability and scalability. Call ission control ensures that voice quality of service (QoS) is maintained across constricted WAN links, and automatically diverts calls to alternate Public Switched Telephone Network (PSTN) routes when WAN bandwidth is not available.



The Link Layer The function is to ensure that if a device sends a packet of information to CM, or CM sends a packet of information to a device, the sent packet is received. CM uses two methods of communication. T and UDP. CM uses T for call signaling and media control with IP phones, H.323 gateways, media devices, and other CM nodes. The CM uses UDP for communication with MG gateways. The Protocol Layer It includes the logic that CM uses to manage the different types of devices tha tip . The device include the media devices, trunk devices, and station devices. It also third-party integration with CM though the TAPI and JTAPI protocols.

The Aggregator Layer It allows CM to properly handle the interaction between groups of related devices. The media resource manager, for example, permits one CM node to locate available media devices, even if they are ed to other CM nodes. The Media Control Layer It handles the actual media connections between devices The Call Control Layer It handles the basic call processing of the system. It locates the destination that a caller dials and coordinates the Media Control, Aggregator and Protocol Layers. Furthermore, it provides the primitives that the Supplemantary Service Layer uses to relate independent calls.

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 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.

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 (DH) server for its network configuration information. The DH 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 T port through which the device connects to those Cisco CallManagers.

CM: Automated alternte routing (AAR) 

[email protected] - CallManager-Workshop BASF

Seite 136

Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number when Cisco CallManager blocks a call due to insufficient location bandwidth. With automated alternate routing, the caller does not need to hang up and redial the called party. The AAR group represents the dialing area where the line/directory number (DN), the Cisco voice mail port, and the gateway are located. For each AAR group, you enter the prefix digits that are used for automated alternate routing within the AAR group, as well as the prefix digits used for automated alternate routing between a given AAR group and other AAR groups. Devices, such as gateways, phones (by means of directory numbers), and trunks,associate with AAR groups. If automated alternate routing of calls takes place, you may also associate devices with an AAR calling search space.
