Is IP Telephony Right for Me? Network Choices and Customer Considerations
http://www.recursosvoip.com/docs/english/News3-IDC_IP_Telephony_Choices.pdf
Formato: PDF
This paper helps audience to make decisions while choosing the telephony systems. IP telephony is developing into an intriguing market by promising value proposition based on cost savings from converged access, management, and administration. It has the potential to unite a large organization's multiple offices into a single telephone system, provide benefits for traveling workers and telecommuters, and bring more of the benefits of computer applications to office telephone systems.
JINI/J2EE Bridge for Large-scale IP Phone Services
http://www.recursosvoip.com/docs/english/j2ee_jini_camera.pdf
Formato: PDF
Using Jini to be middleware for IP phone services will make the IP phone environment more portable, easier to deploy and straightforward to extend. However, many global applications with complex business logic and potentially thousands of concurrent users are developed on J2EE compliant platforms. On the one hand, J2EE is a framework to support large-scale systems while Jini is for small to medium-scale applications. On the other hand, J2EE provides a centralized service whereas Jini offers loosely coupled federations with dynamic administration. This paper proposes architecture called JINI/J2EE Bridge for marrying these two technologies, and allowing J2EE applications to be accessed by Jini.
Leveraging IP Telephony for Disaster Recovery
http://www.recursosvoip.com/docs/english/itmag1-4292702.pdf
Formato: PDF
There is little doubt that IP telephony provides business applications that improve operations and return on investment (ROI). These applications have been beneficial to both small and large businesses and we hear about them often in technical publications and day-to-day operations. What often goes unnoticed, however, is that IP telephony can improve business operations through enhancements in Disaster Recovery planning. Consequently, it does not matter whether you are in the process of deciding if IP telephony is a sound investment for your business or trying to develop Disaster Recovery plans, understanding how IP telephony can be leveraged to improve Disaster Recovery is important.
LION: Layered Overlay Multicast With Network Coding
http://www.recursosvoip.com/docs/english/netcoding-long-final.pdf
Formato: PDF
Recent advances in information theory show that the throughput of a multicast session can be improved using network coding. In overlay networks, the available bandwidth between sender and different receivers are different. This paper proposes a solution to improve the throughput of an overlay multicast session with heterogeneous receivers by organizing the receivers into layered data distribution meshes and sending substreams to each mesh using layered coding. The solutions utilize alternative paths and network coding in each mesh. The paper first formulates the problem into a mathematical programming, whose optimal solution requires global information. It therefore presents a distributed heuristic algorithm. The heuristic progressively organizes the receivers into layered meshes.
Local versus Network Power for Cable Telephony
http://www.recursosvoip.com/docs/english/SADE-5TNRMB_R0_EN.pdf
Formato: PDF
The customer premises network interfaces for cable-based telephony services require continuous power. In many cases, the existing cable network is not configured to supply the needed power. The choices are to provide the power by upgrading the network power system, or to provide local power at each site. This paper describes the features and benefits of these alternatives and summarizes the factors that guide the selection between network and local power.
Local-Exchange Softswitch System: Softswitch and Packet Voice
http://www.recursosvoip.com/docs/english/LocExchSoftswitchSyssoftswitchandpacket.pdf
Formato: PDF
Softswitch is the generic name for a new approach to telephony switching that has the potential to address all the shortcomings of traditional local-exchange switches. The softswitch is where all the service intelligence resides for the delivery of local telephone services. Softswitch technology solutions can lower the cost of local-exchange switching, present the means to create differentiated local telephony services, and ease the migration of networks to support packet voice end-to-end. Packetized voice involves the digitizing, compressing, and dividing of voice into packets. These packets can then be sent from the sender, via various routes, to the receiver, whereupon they are reassembled.
This tutorial is intended to help network planners and technologists who are responsible for the planning and design of local broadband and voice access networks. The focus is on softswitch technology and packet voice and the roles they play in the migration toward fully converged local networking. Broader questions of network evolution are covered as well.

Lucent Technologies' VitalSuite Software: An Effective Tool for Optimizing Voice Over IP Services
http://www.recursosvoip.com/docs/english/ema_vitalsuite_whitepaper.pdf
Formato: PDF
Voice over IP (VoIP), the idea of voice communications traveling over the Internet rather than on the public-switched telephone network (PSTN), was first demonstrated in 1995. Originally dismissed as a novelty, VoIP in particular, and Internet telephony in general, have gained momentum steadily over the years, but nothing like the explosive growth of the Internet itself. In this white paper, EMA focuses on the key network management challenges enterprises face when deploying VoIP services. This paper also describes how Lucent's VitalSuite network and application performance management software addresses these needs.
Managing Call Flows Using SIP
http://www.recursosvoip.com/docs/english/Network_General_Manage_Call_Flows.pdf
Formato: PDF
This is the fifth of six technical briefing papers that discusses the Session Initiation Protocol, or SIP, which is used to manage the call establishment and disconnect procedures within converged networks. SIP, defined by the Internet Engineering Task Force (IETF), has been implemented within a number of systems, including Internet Protocol (IP)-based telephones, IP-based Private Branch Exchanges (PBXs), and carrier networks. SIP provides many of the functions defined in the H.323 standard developed by the International Telecommunication Union — Telecommunication Standards Sector (ITU-T), but with lower complexity and overhead. Key areas discussed include:
- SIP Architecture.
- SIP Messages.
- SIP-related Protocols.
- Case Study: Analyzing SIP Phone Connections.

Formato: PDF
Managing IP telephony is a complex but essential endeavor for any organization planning to adopt IP telephony or any VoIP-based service. Detailed planning of the management systems is critical and must be concurrent with the rollout of the telephony technology itself. Standard management technologies should be used where practical, but specialized IP telephony management products will be necessary. This paper provides an overview of how to implement and manage IP telephony in an organization.
