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

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

Key VoIP technologies: Speech Processing Technology Minimize the bit rate (voice encoding technology, voice detection and suppression technology) while ensuring a certain speech quality) Ensure certain call quality in the IP environment (packet loss co

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

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

VoIP Voice IP) or Internet telephone technology refers to the Communication Service-voice, fax and/or voice and information applications transmitted through the Internet rather than the public exchange Telephone Network (PSTN. The basic steps involved in sending Internet phone calls include converting analog voice signals into digital voice signals and compressing signals into Internet Protocol IP addresses) information packages for transmission over

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

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 networks When 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

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,

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. This article describes the basic transmission process of VOIP.

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

When you look at a VoIP solution, one of the most difficult problems to solve is the labor cost problem. The difficulty of this issue may be second only to the quantification of the impact on user productivity. This is partly because the vendor promises that such integration will reduce staffing while doing marketing, so that your mind will have the impression of reducing staff. However, integration and technical support are new technologies. This tec

I. architecture of the billing systemThe design of the VoIP Billing system follows the design principle of real-time Internet billing, and features real-time, stability, reliability, portability, and scalability. The function design not only takes into account the basic functions of the Internet billing system, it also considers users' needs and the business characteristics of the VoIP system.The core part

above practices and other power-saving strategies, the ROCm chip can improve the power consumption efficiency of WLAN operations, which is up to six times better than the traditional WLAN Chip, thus improving the battery life. A new generation of 802.11 devices that can implement various VoIP applications now include such chips. Import voice to WLAN 802.11 WLAN can use high-performance components to provide reliable overall performance. However, this
