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 ......
Security is often one of the main reasons for enterprises not to use VoIP. Network administrators need to overcome such exaggerated publicity and apply correct security measures to maximize the reliability of voice networks and successfully launch such services.
Changing to VoIP requires many changes. In the old-fashioned TDM (time-division multiplexing) Speech Communication, PBX (switch) is a separate clos
Many people are discussing the advantages of various VoIP services, but when your company decides to use VoIP technology, there are many other decisions that need to be made apart from choosing a service enterprise.
If you have some knowledge about how to send calls to various hardware devices over an IP network and understand the components required for various functions of different components, you can ea
What is Question:pushkit?Answer:ios8 Apple introduced a new framework called Pushkit and a new push notification type, called VoIP push. The push method is designed to provide the ability to differentiate from normal APNs push. This push allows the app to execute the code (before it pops up to the user), and the default behavior of the notification differs from the APNS notification, which does not pop up notifications in its default behavior. At pres
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 network packets to the destination, and then the
IP Voice (voice over Ip,voip) applications more and more popular, common VoIP test model applications include: Test VoIP gateway, VoIP PBX, Gateway Controller (Gatekeeper), proxy server, media Gateway Controller, Soft switches and other internetwork gateways and WAN devices, VoIP
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 organizations and their ability to virtualize
VoIP and data convergence networks are consuming a lot of money from enterprises, but they still have a problem: "Is this network security ?" For Alphonse Edouard, vice president of IT affairs at Dune Capital Management, an investment company, VoIP has become a business foundation. Therefore, it is essential to ensure the security of VoIP.
Edouard said that voice
if your application needs to be able to receive messages sent from the server while the device is hibernating, then we can use the VoIP mode to achieve this requirement. But if the application is not a true VoIP app, then when you submit your app to AppStore it will basically be reject by Apple. But if your app is published internally or you just want to know how it works, it might help. first, how to apply
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
VoIP vulnerabilities have once become a threat to VoIP and its devices, resulting in unavailability or poor call quality. However, a recent finding shows that some types of VoIP attacks can be used to access the data network and steal information.
According to a survey by Sipera VIPER laboratory, portable computers running Vo
With the continuous expansion of data network bandwidth, hundreds of megabytes or even gigabit to the desktop has become possible. The increase of bandwidth also provides a powerful precondition for transmitting voice on the data network. At the same time, VoIP technology is increasingly mature, similar to voice compression, QoS quality assurance, such as the topic has been widely discussed and reached a consensus. It can be said that

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.
