SIP protocol support in unified communications
The SIP protocol provides a standard-based way to provide IP communication for a variety of devices and applications. This white paper describes the current and upcoming support for SIP in the Cisco Unified Communications system. The Cisco Unified Communications System includes IP voice, data, and video communications products and applications that can help organizations communicate more effectively, streamline business processes, and achieve higher revenues.
Cisco Systems provides SIP technology through a comprehensive development plan, including support for SIP RFC on multiple Cisco products. The Cisco plan also integrates SIP RFC and enhancements to the Cisco Unified Communications system. Organizations that adopt SIP-compliant Cisco products can now achieve greater scalability and modularity in their communications. In view of the fact that SIP technology will expand to more communication types, devices and applications in the future, these institutions have also built a rugged platform for the unique and advanced functions brought by the application of SIP technology.
Why consider SIP?
Every year, technological innovation introduces many new devices to provide new methods and new addresses for people to connect. In many cases, it has been found that the convenience of these new devices is greatly reduced by the complexity of managing various tools with different addresses, messages and features, or even overlapping each other. The use of the new device also raises the question of how to communicate with others in the best possible way: "Should I send an e-mail or voice message? For voice messages, which number should I use? Is it his office phone or mobile phone? "It may be cumbersome to share communication information among devices, but a network with a common signaling protocol and an excellent design can greatly reduce its complexity.
By adopting SIP technology, enterprises can solve the above problems and obtain a powerful and flexible platform that can create new communication applications. In a SIP environment, all devices operate as part of a system — users can be reached through a small number of addresses, and users can easily transfer communications from one device to another.
SIP is defined by IETF RFC and is a peer-to-peer multimedia signaling protocol that can be integrated with other Internet services to provide rich communication channels. SIP supports communication between standard terminals such as IP phones, desktop and laptop computers, personal digital assistants (PDAs), and mobile phones. Systems that support the SIP protocol can provide innovative services, including Web-based communication, user movement, presence and preference, and multi-party collaboration.
The advantage of SIP is the indispensable part of IP communication system and intelligent network. In an enterprise or organization, SIP can combine a variety of different applications, devices, and communication processes to provide powerful new functions and features.
The implementation of SIP technology in an IP converged network has many advantages, including the use of new customizable applications to increase network value and user productivity, get rid of the dependence on manufacturers, have greater choice of applications and terminals, and can reduce Equipment costs and expenses for managing communications services. Cisco is committed to supporting equipment that implements SIP-based standard communications to provide customers with the highest investment protection, interoperability, and more deployment options.
SIP professional technical support for Cisco Unified Communications
Cisco Unified Communications Systems has a special advantage in taking advantage of all SIP functions. Cisco employees have played an important role in the process of formulating SIP standards and have been at the forefront of developing SIP technology. In addition, Cisco employees prepared or co-authored SIP-related drafts and RFCs far more than any other company. For in-depth background information on SIP and Cisco's participation in developing SIP standards, please see the white paper: SIP: The Next Step in Implementing Converged IP Communications.
With the industry's largest SIP product line, Cisco is applying its SIP protocol experience to enterprise solutions. Cisco is also working with other companies to ensure that their SIP applications can be seamlessly integrated with Cisco infrastructure.
Customers can be confident that Cisco has a mature strategy of integrating SIP technology, which can protect customers' investment in the field of network and communication systems, so as to safely migrate to the SIP protocol.
