1 IntroductionIn recent years, with the wide application of the IP network technology, more and more researchers are paying attention to the service quality issues that the IP network can provide, scientific and reliable measurement and evaluation of service quality is a critical issue in Network Measurement and network planning and design. As a pioneer in the Next Generation aggregation Service Network Based on packet transmission, VoIP will provide
The combination of communication services and IP networks, especially the Internet, is a natural process that continues to develop along with the generation of e-Mail and instant messages. VoIP-transmitting voice over packet-switched IP networks-is one of the most important trends in the telecom field. The rapid development of VoIP networks has two important factors: the transformation from traditional tele
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 factor in international affairs. In a word, it is widely praised. However, when you use this
For VoIP technology, there are many love, there are many hate. The following is a collection of six "difficult questions" about VoIP applications and reports in the past few years, as well as six reasons not to use VoIP. None of these questions will allow you to eliminate this technology from business considerations. However, all of these problems you have to con
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
China Telecom, China's largest fixed-line telephone operator, was announced last Sunday, Reuters (Beijing, September 12) reported, the VOIP network telephone services that provide voice transmission services over the Internet will be completely banned within the scope of their business areas.
VoIP is a new technology that transfers voice and video files over the Internet and provides communication and data
In the near future, VoIP will become the main way for most enterprises to communicate. For CIOs, you must first understand the five key points of VoIP in enterprise applications.
The comments of commercial technology practitioners on any emerging technology are divided into two parts. They will nod their heads and say, "Good, ......". IP-based Voice technology (VoIP
Currently, VoIP faces security issues of four main: blocking service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. and VOIP protocol security is not negligible pain.
Information security experts will warn you that if you do not deploy VoIP properly, Internet telephony will be attacked by hackers and malicious code.
Overview explanation
VoIP is the abbreviation for voice over Internet protocol, meaning to transmit voice over the Internet (Internet). VoIP technology is also often referred to as network telephony, IP telephony, or Internet telephony technology.
VoIP's most basic function is to provide internet-based, low-cost voice and fax services. It can also extend further to ip-based voice services.
As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful preconditions for voice transmission over the data network. At the same time, the VoIP technology is becoming increasingly mature. topics such as voice compression and Qos quality assurance have been widely discussed and reached consensus. It can be said that the
As long as your network architecture management and preparation are in place, VoIP will be excellent on the wide area network.
Enterprises should know that the performance of the VoIP system is no different from that of the traditional TDMPBX. According to MarkArman, vice president of the ShoreTel marketing department, using VoIP on the wide area network requires

With the development of China's routing industry, we have also promoted the update and upgrade of the VoIP router technology. Here we mainly introduce how to do a good job in the security vulnerabilities of the VoIP router technology. As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful precon
VOIP, also known as IP phone or IP phone, is the abbreviation of Voice Over IP. This technology is used to encode, digitize, compress, and compress Voice signals into Compressed Frames, then, the IP packet is converted to the IP packet for transmission over the IP network, thus achieving the purpose of voice communication over the IP network. The IP Phone greatly improves the utilization of network bandwidth and reduces the communication cost. its wid
VoIP has become a major topic in the era of integration. How to better utilize the functions of VoIP in the aspect of open-source and throttling, and reduce the communication costs of enterprises and individuals has also become a common concern in the industry.
At the beginning, as a technology used in Internet applications, VoIP was widely loved by Internet user
As VoIP continues to replace analog phones in the enterprise voice communication market, this technology is also rapidly adopted in residential environments and Small and Medium-Sized Enterprises (SMBs. The advantages of VoIP, such as multiple lines, the use of cheap digital media voice communication systems, and significantly reduce the communication rate, not only for large enterprises, but also for small
In the field of mobile instant messaging applications, VoIP is the most popular.
Unlike Common Instant Messaging Software, VoIP phones support instant messaging that is traditionally "online, one of the biggest advantages of VoIP is that you can directly use computer, mobile phone, Apple iphone, and other Internet terminals to call a phone to any mobile phone or
