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 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

Point AP (AccessPoint). The Gateway can be the original wired VoIP gateway, so that the voice data is stored in the IP network and the PBX switch). This method enables the functions of traditional wired office phones and residential telephones to be implemented in VoWLAN. operators only need to add devices such as voice gateways and billing systems to provide VoWLAN applications for their WLAN hotspots, efficient combination of data communication and

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

Environment (1 + 1 protection switch ). Summary The Softswitch platform developed by the system platform of linghua cPSB-800 is an excellent solution in the VoIP market. Based on Softswitch, provides a variety of VoIP communication protocols and a common service platform for devices, such as H.323, MGCP, and SIP, as well as user devices such as IP Phone, Gateway, USB Phone, and TA, communication and manage

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. Therefore, before discussing the use of the Internet for voice

methods.Vswitch emphasizes multi-function convergenceEarly VoIP solutions were relatively complex and feature-specific. As the technology continues to improve, a highly integrated communication server integrates communication, video, data, and fax servers. Modern integrated communication devices with Voice/Data/video multimedia services will have a large market.The media switch integrates voice, data, fax, video applications, and IP voice calls. It i

1995 Israel VocalTec Company launched the Internet phone, not only is the beginning of VoIP network telephony, also opened the telecommunications IP prologue. People will not only be able to enjoy the cheaper and even completely free call and multimedia value-added services, the service content and the face of the telecommunications industry has also changed drastically. The beginning of the network phone is in the form of software, and only limited

assurance.　 : VoIP networks without call permission ControlThe network QoS mechanism we discussed in the previous article ensures that voice traffic is not disturbed by other network traffic. It can only control the existing traffic on the Internet. The call permit control ensures that the voice traffic in the network is not disturbed by other voice traffic and controls the traffic entering the network. Call permit control also allows the Voice Gatew

small, it is very simple and the WAN resource overhead is minimal. However, when there are a large number of Voice Gateway routers or New Voice Gateway routers are added, You need to configure each Voice Gateway Router, which has poor scalability. It adopts the control protocol of H.323 gateway and network guard to manage call routes, which has good scalability and simple network configuration. Each H.323 Voice Gateway Router registers its own call i

1. BackgroundWith the popularization of broadband Internet and great technological advances, VoIP has become a technology that can rival traditional telephone services and PBX products. The VoIP Terminal samples and codes audio and video analog signals into Compressed Frames, and then converts them into IP packets for transmission, thus achieving multimedia communication on the IP network. This article anal

QoS Assurance Measures for VoIP services are currently the topic most discussed in the industry. IETFInternet Engineering Task Force) several technical solutions to support QoS are recommended, mainly including: Integrated Service Int-serv) /Resource Reservation Protocol (RSVP), Differentiated Services (DiffServ), Multi-Protocol Label Switching (MPLS), and busine
