The traditional production of PBX is gradually decreasing, and network telephone is becoming t

The VoIP service provider's information online service organization recently released a guide to help new customers select appropriate VoIP solutions. This latest VoIP Guide reflects the increasing demand for VoIP services around the world. According to a recent report from Infonetics Research, revenue from res

Author: OrphousV Tianyang ForumThis time I will show the implementation process of several common attack forms.SIPSession Initiation Protocol (ietf rfc 3261) is a widely used VoIP Protocol. SIP is responsible for creating and disabling multimedia sessions, and VoIP involves multimedia sessions. In a phone conversation, the SIP message exchange method 1 is shown.Figure 1First, the User Agent (User Agent), th

At present, most enterprises in China have already connected to the data network and started to carry out various services, such as office systems, on the network, how to enable your data network to bring more benefits to enterprises is already a very realistic problem for enterprises. On the one hand, we consider using the data network to improve production efficiency, on the one hand, it is highly cost-effective to consider cost savings through data networks, especially for those enterprises w

From the security point of view, VoIP is ineffective, and it has both network and voice network weaknesses. However, the security challenges faced by VoIP are not unsolvable. All we need is a complete security plan. Step 1: three major security threats of VoIP are authentication failure, integrity failure, and privacy protection failure. When implementing

I. Industry Analysis 1. Overall Development Trend of the Communication Industry (1) The development from traditional analog communication technology to digital communication technology represented by VoIP. With the continuous development of IT technology and the wide application of digital technology in various industries, traditional single-function analog communication technology will inevitably be replaced by multi-functional and all-round digital

The softswitch system has a lot to learn about. Here we mainly introduce the best solution for the softswitch system to become a VOIP service, to provide telecom operators with a stable and efficient softswitch system, huaguo Shan information technology uses the Compact PCI architecture as the hardware basis of Softswitch. Leveraging the high-density architecture of the Blade Server, the computing capability of telecom operators exceeding 150,000 BHCA

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

1 Introduction At present, the telecom operation mode is facing a huge change. The traditional telecom business is undergoing profound changes in terms of concepts, technologies, businesses, investment, management and services. The new communication mode will be unified to the IP address. The VoIP (Voice over IP) uses the speech compression encoding technology, the grouping real-time transmission technology and the Control Protocol (RTP/RTCP) the tech

Many enterprises are considering migrating to VoIP. Network administrators have many considerations. The SearchVoIP.com website interviewed Doug Hyde, product line manager of the stack switch of 3Com, about some tips on mitigating this transition and ensuring that the network is ready for VoIP. Q: How can enterprises ensure the service quality of existing networks? Doug Hyde: an important aspect of ensuring

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

on mobile voice services, however, the performance evaluation results of traditional MANET for VOIP services are always unsatisfactory. Here, people are very concerned about whether the wireless mesh network can meet the quality requirements of users for real-time voice services. Iometrix, a professional testing company, conducted the first performance evaluation and testing of Wireless Mesh Networks Based on the draft study by the IEEE 802.11 Workin

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
