Call Manager UC

Cisco call manager unified communications

Cisco Unified Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications. It enables more effective, secure communications and can transform the way in which we communicate. UC represents a communications paradigm shift like that of the invention of the telegraph. UC removes the geographic barriers of effective communications through the use of voice, video, and data integration. Business can be conducted with a fluidity that progresses and evolves with you. Information has been at our fingertips for a long time, but UC enables the sharing of this information to create knowledge and value.

Cisco UC is part of an integrated solution that includes network infrastructure, security, mobility, network management products and third-party communication applications.
Cisco UC can drastically change the bottom line of business by creating more effective communications without losing the personal nature of a face-to-face conversation. More effective communication leads to reduced time to market and nimble transformation of business processes through collaboration.

Cisco UC Solution Components
The Cisco UC strategy encompasses voice, video, and data traffic within a single network infrastructure. Cisco UC equipment is capable of managing all three traffic types and interfacing with all standards-based network protocols.
Cisco IP Communications represents a new way of delivering UC functionality to enterprise customers. Instead of delivering a collection of disjointed products with individual release dates, testing methodology, and documentation, Cisco UC is a coordinated release of an integrated set of products that are tested, documented, and supported as a system.

The components of the standard layers are as follows:

Infrastructure layer

The infrastructure consists of routers, switches, and voice gateways. The infrastructure layer carries data, voice, and video between all network devices and applications. This layer also provides high availability, management, quality of service (QoS), and network security

Call control layer

The call control layer provides for call processing, device control, and administration of the dial plan and features.
Call control can be provided by a CUCM, CUCM Express, or CUCM Business Edition (CMBE).

Applications layer

Applications are independent from call-control functions and the physical voice-processing infrastructure. Applications, including those listed here, are integrated through IP, which allows the applications to reside anywhere within the network:
o Voice mail, integrated messaging, and unified messaging applications are provided through Cisco Unity, Cisco Unity Express, or Cisco Unity Connections products.
o Contact centers of various sizes can be built with Cisco Unified Contact Center and Cisco Unified Contact Center Express.
o Cisco Unified MeetingPlace and MeetingPlace Express are medium- to large-scale conferencing servers that support video integration. The MeetingPlace product integrates lecture-style conferences with scalable collaboration and control tools.
o The Cisco Unified Presence server collects information about the availability and communications capabilities of a user and provides this information to watchers of the user as a status indication. The status information includes the user’s communications device availability. For example, the user might be available via phone, video, web collaboration, or videoconferencing.
o Standard protocol interfaces, including Telephony Application Programming Interface (TAPI), Java Telephony Application Programming Interface (JTAPI), Simple Object Access Protocol (SOAP), Q.SIG, H.323, Media Gateway Control Protocol (MGCP), and Session Initiation Protocol (SIP) are available to support third-party applications.

Endpoints layer

The endpoints layer brings applications to the user, whether the end device is a Cisco IP Phone, a PC using a software-based phone, or a communications client or video terminal. Cisco UC provides multiprotocol support for Skinny Client Control Protocol (SCCP), H.323, MGCP, and SIP.
