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.

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

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

multicast replication is dispersed on corridor switches, which can meet the access requirements of a large number of IPTV users. The solution supports PPPOE and DHCP + authentication. You can avoid the impact between users by Using VLAN or port isolation. Meanwhile, flexible QINQ can be used to precisely locate users and VLAN resources. In addition, the use of BRAS and home gateway to set the user's traffic and priority can effectively control the traffic in the access network, with QOS queue s

New things are always curious and worrying. Just like UC, its technology and market are not yet mature. Many enterprises are also holding a wait-and-see attitude. Therefore, the rise of mobile communication and wireless networks over the years has brought people to notice the Unified Communication UC technology. UC is a new product. This term covers speech, video, legacy applications in enterprise data networks, and network-centric applications. It can be said that UC is a reasonable development

Asterisk is a fully-software PBX system. It can run on Linux, BSD, Windows (simulated), and OS X. It provides all the features you want from the PBX, and is more than the PBX. Asterisk supports four types of VoIP protocols. By using relatively inexpensive hardware, it can interconnect with almost all standard-based telephone devices. Asterisk provides a directory-based voice mailbox Service (VOICEMAIL), teleconference, Interactive Voice Response (IVR

, but the traditional telecom market was not greatly affected. It seems that their business is not in conflict. Until the emergence of VoIP. In fact, the VoIP technology began to appear in 1990s. However, due to bandwidth restrictions and immature technology, the quality of calls cannot be guaranteed, therefore, it is not favored by consumers like Im. However, bandwidth is no longer a problem today. The
