ZTE can also integrated services access network Msan and integrated services access Gateway MSAG and other products to provide customers with a full range of FTTx solutions.

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

construction and can provide a relatively guaranteed multi-service bearer quality. At this time, IP-based voice bearer has become a hot topic in Information Construction exploration. 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

that the ISDN service configuration file identifier (SPID) and switch type are correct. For more information, see Cisco documentation on the isdn test command. VoIP commandsThere are also several available test sub-commands for VoIP. In fact, I will talk about different VoIP test subcommands on Cisco routers in another article. So if you are using

So in development we often need to do something in the background, such as GPs, playing music and so on. So this time we need to manually declare the task in the background: Add the Uibackgroundmodes key value in Info.plist, which contains one or more string va

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

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

If your Skype or Second Life application is frequently disconnected, or when someone starts a World of Warcraft game, your iTunes Transfer Stream becomes congested, consider it, how to improve these problems without buying a new device. In the past few years, most of the wireless routers sold have QoS functions, but you may still want to update the firmware of the router to solve the problem. Let's take a Linksys router as an example. We can make some changes through the configuration program. F

In terms of restructuring the data center, how can we build a UC platform. What aspects should we know about the Unified Communication solution in this regard? Now let's discuss and summarize this question. Hope to help you. Reorganizing a data center Today's enterprise communication industry is a popular trend, that is, the Unified Communication, VoIP system and other communication applications as a software service together with other enterprise app

consider when deploying a Unified Communication System? First, SIP relay. The SIP relay "creates" another channel for external attacks to the enterprise's telephone system. In most VoIP architectures, the PSTN serves as a fireproof channel between the enterprise telephone system and the outside world. Logically, the more isolated the VoIP system is from the outside, the security risks and attacks it faces

application from the drop-down menu, and then select a higher priority level, medium, normal, or low), and then click the Add button. For example, you can set a lower priority for BitTorrent and other download services, and a higher priority for your VoIP service. Speaking of WMM, it is actually a subset of the IEEE 802.11e standard, which defines the quality of service QoS for Wi-Fi ). Without QoS, all applications running on different devices have
