SW CALLMGR 4.1 TO 4.2 UPGD CROM ALL SUPPORTED SERVERS EN
The Cisco® Unified Communications system of voice and IP communications products and applications enables organizations to communicate more effectively-helping them to streamline business processes, reach the right resource the first time, and impact the top and bottom line. The Cisco Unified Communications portfolio is a key part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes which also includes network infrastructure, security, and network management products, wireless connectivity, and a lifecycle services approach, along with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.
Cisco Unified CallManager is the call-processing component of the Cisco Unified Communications System. Cisco Unified CallManager extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco Unified CallManager APIs. Cisco Unified CallManager is installed on Cisco Media Convergence Server (MCS) 7800 Series of server platforms and selected third-party servers. It has a suite of integrated voice applications and utilities, including the Cisco Unified CallManager Attendant Console-a ad-hoc conferencing application, the Cisco Unified CallManager Bulk Administration Tool (BAT), the Cisco Unified CallManager CDR (call detail record) Analysis and Reporting tool the Cisco Unified CallManager Real-Time Monitoring Tool (RTMT), the Cisco Unified CallManager Auto-Attendant (CM-AA), the Tool for Auto-Registered Phone Support (TAPS), and the Cisco Unified CallManager Assistant application.
Cisco Unified CallManager Version 4.2 is an enterprise IP telephony call-processing solution that is scalable, distributable, and highly available. Multiple Cisco Unified CallManager servers are clustered and managed as a single entity. Cisco Unified CallManager clustering yields scalability of from 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking multiple clusters allows system capacity to reach 1 million users in a system of more than 100 sites. Clustering aggregates the power of multiple, distributed Cisco Unified CallManager installations, enhancing the scalability and accessibility of the servers to phones, gateways, and applications, and triple call-processing server redundancy improves overall system availability.
Call Admission Control (CAC) helps ensure 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. With Cisco Unified CallManager Version 4.2, devices can automatically update location information as they move from location to location to improve CAC and emergency service performance.
The enhancements provided by Cisco Unified CallManager Version 4.2 offer improved security, supportability, manageability, as well as usability enhancements to user features, including Park, Hunt Group, Cisco Unified CallManager Assistant, and Call Pickup features that have been supported in past releases.
The Call Park feature now allows users to park a call to a specific park slot. Users now also can have a busy-lamp-field (BLF) and speed-dial button that tells them whether or not the park slot is available. The feature is easily invoked by performing a transfer to the park slot.
With Cisco Unified CallManager 4.2, users now can log their phone into and out of hunt groups. The ability to log out of a hunt group results in shorter call answering times, because callers are not forced to wait for the Ring No Answer timer to expire before their calls proceed to the next phone in the hunt group.
Cisco Unified CallManager Assistant is a valuable application that allows administrative assistants to more effectively support their managers' IP phone activities. It has been ported to an Extensible Markup Language (XML) service that can be run on the phone, allowing assistants that handle executive or manager phones to have the increased features that Cisco Unified CallManager Assistant provides without having to rely on a PC to provide the user interface.
Call Pickup has been enhanced to give an audible and visual notification when a call comes in to the pickup group. Users no longer have to rely on hearing the phone ring to know that there is a call to pick up.
Many customers have security requirements for password aging and one-time passwords. Password complexity rules can now integrate with a Lightweight Directory Access Protocol (LDAP) directory such as Active Directory to provide these security features.
The management of mobile and remote devices is improved with Cisco Unified CallManager 4.2. Cisco Unified CallManager can now track devices as they move from one location to another by mapping the IP address of the phone to a list of configured locations, allowing emergency calls made by mobile devices to call out the correct gateway. This tracking also allows Cisco Unified CallManager to accurately track bandwidth and codec use for CAC purposes.
Call routing to remote phones connected to Cisco Unified CallManager over a WAN has been improved to allow alternate routing when the WAN is out of bandwidth or out of service. During a WAN failure or an out-of-bandwidth situation, the Cisco Unified CallManager can provide routing to the originally called phone number through the PSTN or can call an alternate phone such as a mobile phone.
Voice-quality troubleshooting and tracking has been improved on many of the Cisco Unified IP phones. The phones now report voice-quality statistics, such as mean opinion score (MOS), to help the user and system administrator track voice quality on a call-by-call basis. The phone models support this feature include: Cisco Unified IP Phone 7940G, 7941G, 7941G-GE, 7960G, 7961G, 7961G-GE, 7970G, and 7971G.
