We have already learned about the SIP protocol, which we will always see in the Unified Communication Platform and VOIP business. So here we will give you a brief discussion on the development of the SIP protocol and the SIP protocol stack. 1. About the SIP protocol Currently, there are three basic communication protocols based on VOIP: H 323 protocol, SIP protocol, and MGCP protocol. The following section

Introduction 1. About the SIP protocol Currently, there are three basic communication protocols based on VOIP: H 323, SIP, and MGCP. The following describes the comparison between the H 323 protocol and the SIP protocol. H.323 was proposed by ITU. It attempts to regard IP phones as well-known traditional phones, but the transmission mode is changed from circuit switching to group switching, just like analog transmission to digital transmission, and co

Recently I have heard of many new forms of attacks on LAN, such as Voice over IP (VoIP) attacks or vulnerability attacks (using printers as attack sources. So how can we improve LAN security to prevent these attacks? These forms of attacks are constantly increasing and need to be paid attention to by users. In fact, the SANS Institute has recently listed client attacks as one of the most important vulnerabilities on the internet today. It can be said

As the most fashionable technology, VoIP has received wide attention. One of the most typical applications of VoIP is long-distance bypass, that is, the use of IP networks distributed across the branches of the enterprise to i

So in development we often need to do something in the background, such as GPs, playing music and so on.

zone-h.org, the agency that monitors and records cyber attacks, often uses intelligence from attackers themselves to think that Web servers are being attacked and the number of hacked sites is soaring-a trend that will intensify as more users adopt VoIP technology. But does this mean that the real catastrophe is merely an exaggerated phenomenon? From an IT professional's point of view, it's hard to say. "Is there an increase in the number of attacks o

Brief IntroductionCoordinate Conversion for Android:This implementation is a linear transformation using 7 Parameters(A, B, C, D, E, F and S) to transform the device coordinates (XD, YD)Into screen coordinates (XS, ys) using the following equations:S * xs = A * XD + B * YD + cS * ys = D * XD + E * YD + FXS, YS: LCD coordinatesXD, YD: Touch screen coordinatesIn the compiled Android root file system's system/etc/pointercal file, there are 7 data reco

used to manage SIP devices, such as desktop IP telephony, and also for distribution. Most importantly, it can also be used as a smart point to troubleshoot problems with local devices. Because enterprise communications are the lifeblood of any SMB, the reliability of a purely managed UCaaS solution continues to be a concern, and reliability is one of the most common complaints of end users. A retailer who provides high quality outdoor equipment and clothing for outdoor enthusiasts concludes th

In today's world, the network is more and more high, the communication between people and equipment with each passing day, a wide range. Some of these types of communication are well-known, such as IP voice (VoIP), digital images, multicast, video-on-demand, peer-to-peer file sharing, remote video conferencing, and so on. However, all of these applications have a common feature that the need for network bandwidth can be described as "insatiable". In

the Ethernet data transmission rate is increasing at 10 times times the rate (see Figure B). At the same time, Ethernet is starting to adopt new devices such as wireless and broadband modems. 　 Gigabit Ethernet can be run on the current super five and six types of systems, and prior to the release of six standards, some forward-looking and new technology users have purchased the latest six categories of products for their systems to validate their performance. With six categories of

The Beacon Communication FTTH Voice service solutions are available in two ways: based on traditional V5 solutions and VoIP solutions. For the traditional V5 solution, it is completely handled by the local equipment AN5116, without adding any external equipment, and the open V5 or PRI interface is used t

Switches are constantly evolving along the speed, multi-layer switching, and intelligent exchange directions. A new trend is that intelligent exchange at the edge access layer drives the development of intelligent exchange from the core of the network to the edge. In the past, the network architecture only adopted layer-3 routes of smart switches and layer-4 to layer-7 Smart switches at the core. On the edge, the network architecture adopted common layer-2 access switch products without any netw
