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

1. Definition of VoIP: voice services with certain service quality transmitted over an IP network.
2. 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

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
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
Sometimes, in the development process, if accidentally changed the project Administrator account password and forgot, there is the password in the database is MD5 encryption, this time how to do? The most rookie of me, just at the beginning is also very confused, but to the predecessors consulted for advice, I also checked the data, deliberately sorted out the record, And share them with you.
The premise is that you know which table the password exists in which field, but is

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,
