Cisco Unified CallManager 5.0

Product Introduction

Cisco's Unified Communication System consists of voice and IP communication products and applications, enabling organizations to communicate more efficiently-helping them simplify business processes and get immediate support for appropriate personnel and resources, and increase profits. Cisco Unified Communication series is an important component of Cisco commercial communication solutions. Cisco commercial communication solutions are an integrated solution suitable for enterprises of all sizes, it includes network infrastructure, security and network management products, wireless connections, lifecycle service methods, flexible deployment and outsourcing management options, final user and partner financing service packages, and third-party communication applications.

Cisco Unified CallManager is a software-based call processing component of Cisco Unified Communication System. Cisco uniied CallManager software extends enterprise phone features and applications to group phone network devices, such as IP phones, media processing devices, IP voice VoIP) gateways and multimedia applications. Other data, voice and video services, such as Unified information processing, Multimedia conferences, cooperative contact centers, and interactive multimedia response systems, can be opened through the Cisco Unified CallManager Telephone Application Programming Interface API ), interact with the IP Phone solution. Cisco uniied CallManager can be installed on Cisco Media Convergence ServerMCS) 7800 and a specific third-party server. Cisco Unified CallManager software has released a complete set of integrated voice applications and facilities, including the Cisco Unified CallManager operator console-a software-based manual operator console and a software-based temporary conference application; large-scale management tool BAT); CDR analysis and report CAR); real-time monitoring tool RTMT); and Cisco uniied CallManager operator application.

Main features and advantages

Cisco uniied CallManager 5.0 provides a scalable, distributed, and highly available enterprise IP Call Handling solution. It clusters Multiple Cisco Unified CallManager servers and manages them as a single entity. Integrating Multiple call processing servers on an IP network is a unique feature in the industry. The Cisco uniied CallManager cluster provides scalability, load balancing, and call processing service redundancy for each cluster from 1 to 30000 IP phones. By connecting multiple clusters, the system capacity can be expanded to 100 users in more than 1 million site systems. The cluster aggregates multiple distributed Cisco Unified CallManager functions, enhancing the scalability and access capabilities of servers to telephones, gateways, and applications. The triplicate call processing server redundancy function improves the overall system availability.

Call Access Control (CAC) ensures the quality of voice service (QoS) is maintained in restricted WAN connections. When the WAN bandwidth cannot be used, the call can be automatically transferred to the alternative public switching Telephone Network (PSTN) routing. A Web browser interface for configuring databases supports remote device and system configuration. The HTML-based online help function is available to users and administrators.

Cisco uniied CallManager 5.0 is built on the feature set of Cisco uniied CallManager 4.1 (3. The device provides a call processing platform with software pre-installed on a Cisco media convergence Server MCS) platform. This software is available as a DVD kit for customer servers. A single firmware image of the device contains the operating system and the Cisco Unified CallManager application. Devices can be accessed through the GUI, the life of the PU Mu Ma Yu final shrimp burst mirror in the south of the low chunk zookeeper rolling about it pugang zookeeper N zookeeper dream of stunned zookeeper low farm 4 rows of charcoal accounted for a small number of low-level men and women in the tornchidism, and a small number of chunks in the South were far away. Xie Yunu UI control. Because this version does not support onboard proxy, all Cisco Unified CallManager management interfaces can be closely integrated with third-party applications. The Overall Syslog performance MIB is added to the Simple Network Management Protocol (SNMP) interface. You can maintain the interface to support counters of specific devices. On the programming interface, you can execute the insert, update, and delete database commands. To further improve security, the device has installed the Cisco Security Agent. In addition, Host-Based Firewalls and IP Security IPSec connections between all cluster members are added.

Cisco uniied CallManager 5.0 extends its support for Session Initiation Protocol SIP to support line-side devices, including devices from Cisco and other manufacturers that comply with ietf rfc 3261. Cisco SIP compatible devices include Cisco uniied IP 7905G, 7912G, 7940G, and 7960G. Devices supporting SIP also include Cisco uniied IP 7911G, 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and 7971G-GE.

The SIP relay interface complies with RFC 3261 and allows video calls on the SIP relay. This improves the experience of meeting and application support when used with Cisco Unity and Cisco Unified MeetingPlance.

Cisco uniied CallManager 5.0 supports RSVP proxy. The RSVP proxy on the Cisco router can extend the CAC function in the cluster out of the central distributed topology. Now, a call can be routed directly between two locations without using a hub, which allows the use of a substitute network topology for more efficient use of the network.

Cisco uniied CallManager 5.0 is available in Japanese, Korean, traditional Chinese, and simplified Chinese) versions.

Cisco Unified CallManager can now be managed through SNMP so that administrators can set and report traps based on conditions and send them to the remote monitoring system.

In addition, Cisco uniied CallManager 5.0 provides new management features such as faster addition of new users, line appearances adjustment, site replication, and status group management.

Cisco uniied CallManager provides two operating systems: Windows-based server version 4.x or device model version 5.0 ). The feature improvements listed in this article are only available in the device model.

In addition to Cisco uniied CallManager 5.0, Cisco CallManager 4.0, Cisco CallManager 3.3, Cisco CallManager 3.2, Cisco CallManager 4.0, and Cisco CallManager 3.1 are available.
