SIP Technical Overview
The Session Initiation Protocol (SIP) is a signaling protocol for initiating, managing and terminating voice and video sessions across packet networks. Borrowing from Internet protocols, such as HTTP and SMTP, SIP is text-encoded and highly extensible. SIP can be extended to accommodate features and services such as call control services, mobility and interoperability with existing telephony systems. SIP is being developed by the SIP Working Group, within the Internet Engineering Task Force (IETF). The protocol is published as RFC 3261. This section describes the key constituents of SIP.

SIP Server Technical Overview
SIP Servers are essential network elements that enable SIP endpoints to exchange messages, register user location, and seamlessly move between networks. SIP Servers enable network operators to install routing and security policies, authenticate users and manage user locations.
SIP Server applications may take many forms, but the SIP standard defines three general types of server functionality that apply to all-proxy, redirect and registrar servers. These standard functionalities can be used according to the needs of the specific implementation.
With the advance of SIP, server logic has become increasingly complex. SIP Servers need to deal with varying network topologies (such as public Internet networks, cellular networks, broadband residential networks), complex routing policies, security and SIP extensions. SIP Servers often need to handle high message/transaction rates and yield real-time performance and scalability, high throughput, and low delay. This chapter discusses the protocol aspects of SIP Server behavior and the usage of the RADVISION SIP Server Toolkit to address the challenges of effective SIP Server development. Download >>>

SIP - A Powerful Protocol
During the last few years SIP has been adopted by many vendors who choose to add SIP-based product to their portfolios. This is primarily because SIP delivers powerful extensibility and enhanced features such as Presence and Instant Messaging to voice and video over IP solutions. Additionally, the ubiquity of SIP enables not only the set up and tear down of voice and video sessions but also enables the implementation of different value added applications.
For all of these reasons SIP is in the position of becoming a widely deployed protocol as the IP communications market continues to grow and evolve. Read the full article >>>
