Voice communication over the Internet is a very complex system engineering and has a wide range of applications. Therefore, many technologies are involved. The most fundamental technology is the VoIP (Voice over IP) technology, it can be said that Internet voice communication is the most typical and promising application area of VoIP technology. Therefore, before discussing the use of the Internet for voice

What is VoIP? The complete name of VoIP is voice over Internet protocol, which is translated as Internet voice. It can be simply understood as a technology that uses an Internet system instead of a traditional telephone communication system for voice calls. In fact, the biggest difference between the two is that traditional voice calls use analog signal technology, which is prone to interference and difficu

The market advantage of VoIP is obvious. This voice technology, developed by the long-distance method, has impacted the market at its ultra-low price. How is the system of voice character completed by means of network? Now let's talk about the components of the VoIP system. Due to many developments and technical breakthroughs in related hardware, software, protocols and standards, the widespread use of

In recent years, with the continuous development of communication technology, a new technology has emerged. It integrates voice technology with network transmission, enabling data transmission on the Internet, it can also transmit voice and images. It is widely used to give full play to the role of the network, reduce repeated investment in equipment, reduce costs, and reduce expenses. This is the VoIP technology.

The transition to VoIP will incur a huge cost for enterprises. This requires a lot of time and money. From the largest enterprise to the smallest enterprise, manageable VoIP has become a reality. Many companies just don't have time to do this on their own. They need to hire a service provider to monitor the transition to VoIP and ensure high reliability and perfo

architecture? In the fuzzy definition of NGN, some people think that Softswitch is NGN, while others think that the traditional PSTN voice service supported by Softswitch is the whole of NGN. Yin Kang, Cisco's Asia Pacific NGN/VoIP chief technical consultant, believes that the ambiguity of the Softswitch technology concept reflects the industry's misunderstanding of softswitch in some aspects, there is a situation where the capability of one aspect i

By deploying VoIP phones in 250 offices and 10000 nodes, you can learn something about this technology. As a result, Alok Kapoor, managing director of Merrill Lynch Global individual customer Technology Global Private Client Technology, said in VoiceCon that he had specific suggestions on the implementation of this Technology. 1. There is a good measure of the performance of the existing system. Kapoor repeatedly stressed that the lack of information

In the past two years, unified communication has been a hot topic among vendors, especially among traditional communication equipment vendors. Zeus Kerravala, an analyst at the market research company Yankee Group, said, regarding the positioning of Unified Communication, most vendors use VoIP as the basis for Unified Communication, and use Unified Communication as a "thing" built on the basis of VoIP ". He

Recently I have heard of many new types of LAN attacks, such as VoIP attacks or the use of printers as attack sources. So how can LAN security measures protect us from these attacks? These attacks are on the rise. This is definitely a fact. In fact, the SANs Research Institute recently listed client attacks as one of the most serious vulnerabilities today. However, if anyone of us thinks we can fully protect ourselves from such attacks, we will be bra

No matter whether enterprise users are ready or not, IPv6 network deployment is just around the corner. The demand for advanced site selection technology is growing, and everything in life will be able to use this technology. At the same time, VoIP has become the mainstream technology and has become the basis of other network services. It is no longer the concept of "Next Generation" voice networks. So our worries also follow: What impact will these

Next we will introduce the VoIP protocol. We all know that VoIP is one of the most popular network businesses. The Application Basis of this Service is also a VoIP protocol. We will introduce this protocol in detail. VoIP protocol Currently, VoIP protocols are commonly used,

grouping network. It also provides users with both voice, data, and multimedia services through a converged network. At the 2006 China Information Industry Economy Annual Meeting, Zhao huiling, Vice President of China Telecom Group's Beijing Research Institute, pointed out: "to achieve integrated services to provide platforms, integrated business management platforms, and portal to differentiate customer groups, this is our long-term goal. Then, we stop Circuit Switching in the entire exchange

The VoIP network protocol is the support for VoIP services. In network communication, the use of this Protocol forms this business, and it is challenging the traditional communication market and traditional communication methods to the maximum extent. Let's take a look at this powerful VoIP. VoIP network protocol Curre

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
