pstn conferencing

With the rapid development of computer and network technology, the traditional means of communication can't meet people's demands. Companies require the ability to conduct remote meetings and business exchanges , and in addition to meeting the basic requirements of traditional video conferencing audio / video Communications, modern conferences are more interested in providing a more diverse range of meeting discussions and functions. For example: Rem

academic research, we should translate Softswitch into soft switch more accurately. In the formal written language, "Softswitch" should be avoided as a short name for soft switches. There have been a lot of discussions about vswitches, and people have basically agreed on the technical characteristics of vswitches. Vswitches use MGCP/H.248 media control protocol technology to separate call control from media bearer. Therefore, some foreign scholars refer to soft switches as call proxy CA or medi

technology must use public transmission media. In other words, enterprise private network platforms cannot implement this function, although some network technologies can break through the LAN coverage, so that the transmission distance can reach several kilometers or even dozens of kilometers. Regardless of the construction cost, the requirement of Flexibility alone cannot be met by the private network. ◆ Various access channels are emerging For these reasons, remote access technology has long

. Therefore, the author believes that for the seriousness of academic research, we should translate Softswitch into soft switch more accurately. In the formal written language, "Softswitch" should be avoided as a short name for soft switches. There have been a lot of discussions about vswitches, and people have basically agreed on the technical characteristics of vswitches.

With the rapid development of the Internet era, online video conferencing has become one of the most important tools for business communication. Many enterprises have also seen business opportunities brought about by video conferences, so they are entering this industry. However, as domestic video conferences are still in development and lack of industry standards, the entire industry is in a state of disorder, for example, many video conferences clai

to build and maintain through servlet and JSP models-View-control architecture, but they are basically text-based, it is rarely integrated with a variety of collaborations used by some Windows-based applications, such as various VB controls that can be integrated with audio and video-based media applications. Figure 1 user experience More and more people expect Web applications to integrate traditional HTML interfaces with functions such as instant messaging, voice over

I. Introduction When a call is established for a traditional telephone exchange network, the signaling point code of the next exchange board is determined based on the E.164 number of the called phone number, and then the call is routed through the No. 7 signaling network according to the signaling point code, the essence of all call routes is to determine the signaling point encoding according to E.164, and then use the signaling point encoding for call routing. Unlike the traditional

Here we will be generated by conversations between the users of the media called the regular media ("regular medium"). Early media ("Early media") is compared to

NGN's streaming media service not only provides video stream services, such as broadcast and television and VoD, but also integrates voice, data, and video services for common and commercial users, for example, Caller-IDonTV ). At present, the NGNRelease1 architecture established by ITU-TFGNGN-FRA includes the IP Multimedia Service Section (including the simulation service of PSTN/ISDN) and the simulation service section of

interface between GSM system and other public telecommunication networkOther public telecommunication networks mainly refer to public telephone networks (PSTN), Integrated Services Digital Networks (ISDN), packet-switched public data networks (PSPDN) and circuit-switched public data networks (CSPDN). GSM systems are interconnected with these public telecommunication networks through MSC, and their interfaces must meet CCITT's relevant interfaces and

network, the operator's control over the network is reduced, and the control mode has undergone great changes. Through the above analysis, using the SIP Softswitch protocol will lose some existing functions in the telephone network to some extent. To introduce these functions, you need to expand the SIP Softswitch protocol. BICC provides basically all existing telephone network functions. We believe that the modified and standardized SIP can provide BICC with support for traditional services. C

Mobile video development Let's put the meeting room in our pocket.In this era, the mobile phone by the developers of the meaning has been far beyond the expectations of the public, with the Internet, the completion of electronic shopping, reading, read magazines, it seems that the main part of the phone call, send information has become an auxiliary function.Now, mobile phones in the " smart " premise, has become more and more occupy people's living space, because, in the Android,IOS and so on s

We all know that the Softswitch technology supports many different protocols from different standardization organizations. Here we analyze the next generation radio/TV Network Technology Based on the Softswitch technology. How to build a sustainable network, integrate data and voice services, speed up user-oriented business development, and improve its flexibility, to ensure that carriers can gain their expected market share in the future data multimedia business, this is the fundamental startin

existing telephone network functions to some extent. To introduce these features, you need to expand the SIP protocol. BICC provides basically all existing telephone network functions. We believe that the modified and standardized SIP can provide BICC with support for traditional services. Comparison of SIP-T and SIP-I There are two standard systems about intercommunication between Softswitch SIP domain and traditional PSTN, that is, SIP-T protocol f

suppliers have a set of tariff policies that suit their own characteristics based on their business needs. However, they must abide by the principle of uniform rate, only one Billing value can be calculated for a service under this billing policy, and there cannot be any ambiguous billing method.The most common billing methods are:1) billing by service duration, which is the most widely used billing method;2) billing by service count;3) paybytraffic may be upstream traffic, downstream traffic,
