SIP, RTP, and XMPP in the Emerging Real-time Internet
This white paper discusses how Session Initiation Protocol (SIP) , Real-Time Transport Protocol (RTP), and Extensible Messaging and Presence Protocol (XMPP) can work together to harness the unique strengths of each protocol within and across applications. Each protocol has a role in powering the real-time Internet, and this paper highlights how they complement each other to create a whole solution.
The Power of Presence
Presence is a key technology powering the real-time Internet. Forward-thinking businesses, service providers, and government agencies are already reaping the benefits of presence-enabled information exchange. This paper explores the nature of presence data, its value to the organization, and methods for leveraging presence to create strategic value and competitive advantage.
Beyond Instant Messaging
Speed and agility are increasingly important elements to success in a wide variety of domains. As a result, the Internet is becoming a more dynamic, user-centric, real-time environment. In this white paper, we explore characteristic technologies of the real-time internet and how enterprises, governments, service providers, and other organizations can leverage those technologies to build competitive advantage in today’s fast paced world.

"Break Free" - Leveraging SIP in Developing Enhanced Applications
Over the last 15+ years, literally thousands of enhanced applications have been developed for the legacy telecommunications infrastructure. From simple voicemail, to sophisticated contact center solutions, these Computer Telephony Integration (CTI) applications have built value on top of basic PSTN dial-tone, generating substantial revenue in both products and services. However, many of the CTI applications were developed using a restrictive and hard-to-learn architecture that limits the developer’s choices in operating systems, choice of technology suppliers and incurs other serious restraints. This whitepaper outlines a migration strategy that leverages SIP to eliminate many of the past restraints and show how to “break free” from the bonds of the legacy CTI architecture.
Building Applications with SIP - the IP Contact Center
The legacy call center has gone through a metamorphosis, emerging as the IP Contact Center which replaces the PBX and separate IVR and ACD systems and merges email and instant messaging into a new architecture that integrates these functions, leveraging Voice over IP technologies. Whether the goal is to reduce costs in the existing call center, leverage inexpensive overseas labor or add Work At Home Agents (WAHA), IP Contact Centers provide tremendous flexibility to adapt to changing markets and labor resources. By reading this whitepaper, you will learn how SIP can be leveraged as a key enabling technology for the IP Contact Center - delivering scalable and cost effective solutions while avoiding restrictive and expensive API development.
Building Applications with SIP - Conferencing / Collaboration Solutions
Global organizations utilize conference calls as a very important business tool for collaboration. Multi-branch organizations were the first to recognize the value in voice and video conferencing services to economize on travel costs and to coordinate business activities. Other smaller organizations have also begun to recognize that having access to easy-to-use conferencing resources speeds collaboration efforts with clients and suppliers. Whether using a tradition TDM PBX, an IP-PBX or a hosted service provider, SIP is seen as a key technology going forward to help tie organizations together and dramatically reduce the costs of conferencing. By reading this whitepaper you will learn how SIP can be leveraged as a key enabling technology for conferencing and collaboration applications - delivering scalable and cost effective solutions while avoiding restrictive and expensive API development.

SIP Trunking Benefits and Best Practices
A SIP trunk is a service offered by an ITSP to use SIP to set up communications between an enterprise PBX and the ITSP. A trunk includes multiple voice sessions – as many as the enterprise needs. While some see SIP as just voice, SIP trunking can also serve as the starting point for the entire breadth of realtime communications possible with the protocol, including Instant Messaging, presence applications, whiteboarding and application sharing.
