Readers who have a long memory and a history of online trading may also vaguely recall that the creator of the famous PGP (Pretty Good Privacy) software, security expert Phil Zimmermann, launched a "Pgpfone" in 1996. of Internet telephony products. About three years later, broadband networks really started to grow. This is the early stage of the network telephony development cycle. Pgpfone a little too far ahead, not to arouse people's attention. But the world must be careful! Security expert Ph

Like Voice over IP (VoIP), from the beginning of the network economy boom, IP Network Videos are both popular and challenging. We have already experienced fraud when purchasing too much, and now most customers have become sophisticated, buyers and IT departments have become more realistic about when and how their users use video systems. In this article, we will mainly talk about how voice managers or network managers should make decisions on this iss

The VoIP network protocol is the basis of the network telephone. It has been widely used in network communication. The use of this Protocol forms this business and challenges the traditional communication market to the maximum extent, and traditional communication methods. Let's take a look at this powerful VoIP. VoIP network protocol Currently,

1. BackgroundWith the popularization of broadband Internet and great technological advances, VoIP has become a technology that can rival traditional telephone services and PBX products. The VoIP Terminal samples and codes audio and video analog signals into Compressed Frames, and then converts them into IP packets for transmission, thus achieving multimedia communication on the IP network. This article anal

High quality: KC Network telephone, independent intellectual property IP VoIP Network telephone voice engine technology, the international leading quality comparable to traditional telephone calls.Very practical: KC computer software/mobile software download, the use of computer calls, Internet phone calls, mobile phone calls, such as the way to provide.Super Save money: The provision of internet telephone free 60 minutes, domestic long-distance to 5

In traditional speech, we all communicate in Wired form. The first time was a analog signal, followed by a digital signal. Now, our voice communication methods can be implemented through network IP addresses. This leads to today's topic-VoIP and VoWLAN. VoWLAN Overview VoWLAN is one of the emerging applications of WLAN. VoIP transmits voice signals through a data network; WLAN), and uses wireless access poi

QoS can give priority to voice communication services under limited network resources. However, if too many voice communications occur, the network may be congested. How can this problem be solved?Call Control for enterprise VoIP networksWhen we configure the QoS function that supports voice on an enterprise's IP network router and switch, this IP network is ready to carry the voice application. However, in order to achieve the call, we also need to e

the Internet can make full use of the network and increase the chance for students to communicate and communicate with the outside world, the cost of communication between students and schools is reduced. However, this communication method requires less investment in the early stage, which is convenient to use and must meet the personalized communication characteristics of students, another important selling point is long calls and low costs. II. Introduction to

Application VoIP service quality (QoS) has four key steps: Application VoIP service quality (QoS) has four key steps. If you do not follow these four steps, your VoIP implementation will not realize its full potential. In addition to enabling the vro function, QoS has many things to do. Therefore, it takes some time for you to plan and design the correct QoS for

I. Overview As we all know, a company's business activities depend heavily on modern communication methods. Exchange of telephone, fax, data, and information is the fundamental guarantee for the survival and development of enterprises. At the same time, the extensive use of these devices has brought a burden to enterprises and increased their operating costs. In particular, large international groups and large enterprises have paid a lot of money for this. In recent years, with the continuous de

A router is a commonly used network device. How should we configure VOIP implementation? What are the specific operation steps? The following article will give you a detailed introduction. Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technolo

In Unified Communication, we can see many representative services, such as video communication and instant communication ...... Among them, VoIP is one of the "everyone". So why should we integrate VoIP into the field of Unified Communication and how should we integrate VoIP into the planning of enterprises? Today's enterprise communication industry is a popular

Is the network only an infrastructure? Obviously, the current applications have prompted the network to shoulder greater responsibilities. There are still some standard problems to integrate IP speech into traditional networks. What will happen in the future?When is the call no longer a traditional call? VoIP answers this question.All kinds of signals were transmitted through copper wires before January 1, 100. Later, radio broadcast and television si

Application Guide: clarifies the concepts of managed and hosted VoIP Managed, centralized user switch, and hosted VoIP. Oh, my God! There are many available products for enterprises looking for alternative products for the indoor telephone system. This product has various types and sizes. Hosted speech, IP centralized user switches, managed ip pbx, and network-based voice services are all alternative produc

emerging CTI (computer-telephone integration) and VoIP, and traditional PBX uses dedicated technologies, lack of openness and standards, and expensive. In recent years, with the popularity of the Internet and the success of IP, IPPBX Based on the IP protocol has emerged and is expected to solve the shortcomings of traditional PBX. The IPPBX telephone switch system will play an important role in the Communication Industry in the 21st century by integr

At present, many devices are often converted through routers and firewalls. However, the price of the devices that want to meet the OC192 line rate is usually very high, and the investment in comprehensive monitoring of the entire network is very huge. Therefore, using special algorithms and devices to analyze network data while reducing device prices is a feasible solution for the whole network monitoring of VoIP. This paper proposes a new algorithm

In recent research, Forrester recommends the following six steps to help IT organizations avoid VoIP security risks and ultimately ensure their UC systems are secure. In many companies, data networks and telecom worlds converge, and voice and video traffic runs on the same network as other data in the enterprise. Well-known industry terminology such as IP voice (Voice over IP, VoIP), IP telephony (IPT) and
