Session border controllers (Acme Packet)hot!

Regardless of opportunity, interactive communication over IP networks must be able to reach anyone, anywhere, anytime to maximize its value. To paraphrase Metcalfe's Law: the usefulĀ-ness, or utility, of interactive cormnunication equals the square of the number of users. New interactive communication services and applications, therefore, must ultimately span business and consumer, wired and wireless networks.
Consequently, simply building standalone voice, video and multimedia over IP network islands is not sufficient. They must be built and interconnected in a way that ensures security and peak performance end-to-end. Businesses and consumers will be satisfied with - and pay good money for - nothing less.

Session Initiation Protocol (SIP) and MCI AdvantageĀR White Paperhot!
- 01.06.2003
- Global IP communications over the Internet is probably the most significant development since the emergence of telephone networks over 120 years ago. In this paper, we explore the new communication services enabled by the Internet, including examples of new and potential services.

Present enterprise communications systems and applications provide integration of voice and data services. Still, proprietary technology and architecture discrepancies make it difficult to implement and deploy new converged communications services. The Session Initiation Protocol (SIP) brings user centric Internet Telephony. This model provides new converged communications services based on presence, mobility and user preferences. SIP technology promotes distributed architecture models, and seamless integration with IP technology. SIP is an open extensible Voice over IP (VoIP) protocol and is a framework for building voice and data communication applications. This article presents what SIP brings to enterprise communication applications and how customers can manage a smooth transition to SIP based services with the example of the OmniPCXIP communication server.

The development of VoIP has been characterized by a perpetual battle to deliver the full-range of applications end users and service providers want, while balancing that with manageability and a straightforward design that eases deployment and development. One protocol that has fit that bill is the IETF's session initiation protocol (SIP).

Overview of H.323 - SIP Interworking (Radvision)hot!
- 16.05.2001
-
Looking at IP networks and VoIP, it is clear that both protocols - SIP and H.323 - are widely deployed and here to stay. For carriers wishing to provide global VoIP services, the interconnection of these disparate networks into a unified VoIP network is an urgent and high priority. The SIP-H.323 InterWorking Function (IWF) has been defined as a logical entity that allows the interworking between the SIP and H.323 protocols. This includes call sequence mapping, message parameter mapping, translation between H.245 and SDP, state machines, and the handling of different call procedures.
This paper looks at the issues and challenges of the IWF and presents a number of approaches for achieving the necessary functionality.
