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
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.

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

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.

802.11 WLAN can use high-performance components to provide reliable overall performance. However, this
The combination of multimedia applications and traditional enterprise networks has become commonplace in enterprises. In particular, with the steady development of VoIP technology, IP voice has gradually become an indispensable new member in the enterprise network. However, this poses new challenges to enterprise network security. Recently, more and more attacks have been initiated against enterprise VoIP a
