share a network. According to Edouard, the new QRadar module designed specifically to monitor VoIP networks meets this requirement. This VoIP module integrates network behavior analysis and security event Association to monitor the protocol, application, and security service layer of the entire network. Tom Turner, vice president of marketing at Q1 Labs, said co

VoIP (Voice over IP) is a shining noun in the IT industry and telecom industry at this stage, and we can literally know what it is to solve the problem of technology. To put it simply, the basic principle of VoIP is to compress and encode our voice with voice compression devices, then the voice data according to the relevant protocol packaging, through the IP net

, using IP Relay for the interconnection between headquarters and branch nodes can save the high cost of renting long-distance circuit relay. Therefore, VoIP technology in the enterprise-class user community will have a wide range of applications. However, in the implementation of the project or in the use of the process, users and equipment suppliers will be more focused on how to improve the voice quality and integration with the existing data netw

traditional phone number or mobile phone number on the public network. The most famous software phone number should be Skype. The following are some business-oriented software phone products: 3CX VoIP Phone for Windows: This is a software that uses the call Initiation Protocol (SIP) technology. The free version and Enterprise Edition are available. It supports services of Asterisk and Sipgate network telep

The earliest VoIP technology service was created to solve the long-distance telephone bill problem. However, with the continuous improvement of technology, the VoIP technology service has gradually expanded its scope, video, fax and other services, and it can also achieve low-cost and high-quality transmission functions. In itself, this has already greatly impacted the market ......

of Windows or Linux-based operating systems, these operating systems are more widely supported by developers and the possibility of application integration. However, this does not enable these operating systems to have more security vulnerabilities. As for whether organizations should use products based on Windows and Linux operating systems or products based on other operating systems, there is no correct answer for enterprises. This is just a matter of choice. If a standard-based product is u

VoIP Overview: VoIP (Voice over Internet Protocol) is a communication device that uses an IP network to transmit Voice and save user calls. It is mainly suitable for enterprises and group users with branches, it can save enterprises a lot of international, domestic and suburban long-distance calls. VoIP can digitize th

were vulnerable to buffer overflow attacks, resulting in phone paralysis. However, a similar attack uses the SIP protocol to exploit this overflow attack. This attack embeds the code into the SIP protocol, arrives at the victim machine, and establishes a connection from the victim machine to the hacker computer, allowing the hacker to view, copy, delete, or steal files. Joglekar said the vulnerability was

As enterprises move towards server virtualization, does the VoIP/ipserver adapt to the server consolidation plan? The answer is yes. PBX (Programmable switch) was previously an independent proprietary system. With the emergence of Internet protocol Voice Technology (VoIP) and network telephone technology (IPTS), PBX has become a system-based server. Why Should or

latency exceeds 3% ms or the packet loss rate exceeds, the call quality will be greatly affected. In addition, with congestion and other unpredictable factors, we can infer that the biggest weakness of VoIP is that it is highly sensitive to interference. DoS attacks are widely known as interference attacks. Attacks against VoIP (such as sending a large number of specially constructed packets) will cause de

the principle and technology of VoIPVoice communication through the Internet is a very complex system engineering, its application is very wide, so the technology involved is also particularly many, the most fundamental technology is the VoIP (voice over IP) technology, it can be said that the Internet voice communication is one of the most typical VoIP technology, It is also the most promising application

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

operators and equipment vendors cannot effectively avoid risks, long-distance VoIP will reappear, and local Softswitch will return to the PSTN to a certain extent. We should realize that voice is only one of the services in the next generation of telecommunication networks. Data features in network services will be even more prominent. Carriers and equipment vendors should not regard Softswitch as only one telephone platform. The soft switches that o

possible to transmit files through FTP; while ERP applications send less data, but they exchange data streams frequently between the sender and receiver. On the contrary, VoIP only occupies a small amount of network bandwidth, but it cannot tolerate network latency and changes. Even if the VoIP service and traditional data service are implemented in the same network, the voice stream and data stream cannot

VoIP refers to voice transmission over a network that uses the Internet Protocol. The IP address represents the Internet Protocol and is the hub of the Internet, internet protocols can transmit emails, instant messages, and webpages to thousands of PCs or mobile phones. Some people say it is the killer of telecommunications, and some say it is a revolutionary fac
