Evolving to Converged communication with SIP (Avaya)hot!
- 11.05.2005
-
Organizations with multi-vendor, multi-application and widely distributed communications systems need a reliable way to integrate and optimize their network infrastructure. Session Initiation Protocol (SIP) supports converged communication applications by placing control of the communication across distributed networked entities and smoothly integrating the various system levels. SIP enables seamless data and voice convergence in multi-vendor environments with multiple applications across a wide range of industry sectors.
This white paper is designed to help business leaders understand the impact of SIP-based converged communication in Voice over IP (VoIP), Unified Communication and Customer Relationship Management (CRM) solutions. This paper also offers CIOs guidelines for migration to an enterprise SIP network, and details some new Converged Communication Solutions.

Secure IP Telepony for the Enterprisehot!
- 11.05.2005
-
Security is an important consideration when implementing VoIP because each element in the VoIP infrastructure, accessible on the network like any computer, can be attacked or used as a launching point for deeper attacks. In addition, VoIP presents certain specific security challenges. Lastly, Session Initiation Protocol (SIP) is a new application protocol for VoIP and the firewall must understand this protocol to properly enforce the companyâ_Ts security policies.
Pingtel and Check Point offer a VoIP solution that addresses these concerns. This white paper discusses both the issues, and proposed solutions.

November, 2003
Abstract: SIP (Session Initiation Protocol) is a standard protocol that covers a wide variety of applications. The document explains why SIP is a powerful real-time collaboration protocol. SIP is currently being adopted by many companies and is evolving more rapidly than any other existing real-time collaboration protocol. This document provides background information on SIP and touches the wide variety of applications whose implementation is either made easier or made possible, via SIP. This document concludes with a set of questions and answers on SIP.

Executive Summary
Session Initiation Protocol (SIP) is continuing to develop rapidly and it is difficult to keep up with all of its innovations and uses. This white paper is aimed at people who want to understand the concepts and drivers behind SIP adoption, and how it is evolving to face new challenges. This paper summarizes where SIP has come from, how it works, and what makes it such a useful protocol. It then describes how SIP is used in applications including telephony, conferencing and messaging, and how it is being extended to provide innovative services and accommodate the requirements of real-world deployment, where NATs, service level agreements and regulators exist. In covering this broad range of SIP-related topics, it provides a summary of the state of this increasingly important protocol.

SIP Server Technical Overview (Radvision)hot!
- 21.07.2004
- 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 Platform to address the challenges of effective SIP Server development

SIP: Protocol Overview (Radvision)hot!
- 20.02.2004
-
The Session Initiation Protocol (SIP) is a signaling protocol for initiating, managing and terminating voice and video sessions across packet networks. SIP sessions involve one or more participants and can use unicast or multicast communication. Borrowing from ubiquitous Internet protocols, such as HTTP and SMTP, SIP is text-encoded and highly extensible. SIP may be extended to accommodate features and services such as call control services, mobility, interoperability with existing telephony systems, and more.
SIP is being developed by the SIP Working Group, within the Internet Engineering Task Force (IETF). The protocol is published as IETF RFC 2543 and currently has the status of a proposed standard.
This White Paper describes the key constituents of SIP.

Enterprising with SIP - A Technology Overview (Avaya)hot!
- 02.02.2004
-
The vision that Avaya has for converged voice and data communications is to create a network environment that supports maximum enterprise efficiency. Session Initiation Protocol (SIP) [18] is a key technology for this evolution towards a converged communication architecture. SIP as an enabler of converged communication applications has been able to gain industry-wide acceptance by placing control of the communication across distributed networked entities and by providing a means of integration at various levels in the protocol stack. Such integration is now possible in a multi-vendor environment with multiple applications across a wide range of industry sectors. Converged communications that is driven by ubiquitous IP network connectivity defines the next stage of evolution in enterprise communications.
SIP is an application layer, peer-to-peer communication protocol that facilitates openness, simplicity, flexibility, and reuse in an "All IP" Architecture. This paper offers a look at how Avaya views SIP in enterprise evolution. It also describes SIP technology, elaborates on the role of SIP in realizing converged communications, and describes details of the SIP protocol and associated technologies.

Robustness testing of SIP implementations (Codenomicon)hot!
- 18.11.2003
-
Introduction
SIP[4] will be a part of future IP telephony infrastructure, raising new security concerns and issues. As past experience has shown, a majority of these problems are due to software vulnerabilities. One class of software vulnerabilities is introduced during implementation, in the coding process, due to non-robust handling of input data. An example listing of vulnerability types and failures is in Table 1.
One way to counter these vulnerabilities is to do white box testing and to perform code audits. This white paper discusses this process.

SIP Specifications and the Java™ Platformshot!
- 01.09.2003
- The goal of this whitepaper is to identify the specifications to the Session Initiation Protocol (SIP)[1] defined through the Java Community ProcessSM (JCPSM) [2]. This document inspects each Java SIP specification describing the functionality, architecture, platform supported and how each interface relates to the other Java interfaces to SIP. This is not a tutorial on SIP or the Java language [3] and it is assumed that the reader has a reasonable understanding of both the Java language and the SIP protocol and their potential functions within an IP Communications network.
