This tool is a real-time analysis of the SIP Communication Protocol, which is the main function of the Communication Engineering of zhongzheng University. In addition, the distributed design can be used to analyze cross-domain sip packets, draw a complete signaling flowchart, and control the web interface... background in view of the fact that there is no free communication protocol analysis software for th

Network integration of video surveillance services based on Ngn/ims (SIP Protocol) communication Platform

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to solve the problem: From the monitoring industr

SIP's most popular communication protocols are mature

Introduction Communication providers and their partners and users are increasingly eager for a new generation of IP-based services. Now we have the SIP Session Initiation Protocol. SIP was born less than a decade ago in the computer science laboratory. It is the first protocol suitable for multi-user sessions in various media content. Now it has become the specification of the Internet Engineering Task Gro

SIP protocol (Chinese)-1

1. Introduction to the SIP protocol Many applications on the internet need to establish and manage a session. The session here refers to the exchange of data between participants. Considering the actual situation of participants, the implementation of these applications is often very complicated: Participants may move between agents, they may have multiple names, the communication between them may be based on different media (such as text, multimedia,

In general, SIP is a lightweight signaling protocol, which can be used as a signaling for audio, video, and timely information. Speaking of how the SIP is coming out, we need to mention H.323, and the standard has to mention ITU-T, we will first talk about t

Voice and IP communication: Support for SIP protocol in Cisco Unified Communication (1)

The SIP Protocol provides a standard-based IP communication method for multiple devices and applications. This White Paper describes the support for the SIP protocol in the Cisco communications system. Cisco's Unified Communication System includes IP voice, data and video communication products and applications, which can help organizations communicate more effectively, simplify business processes, and achi

Using SIP to encapsulate C + + as Python

SIP is a tool for generating C + + interface code for Python, similar to SWIG, but using a different interface format. The idea originated in Swig, primarily to create the QT package for Python, which was used to create PyQt and Pykde , and to support the QT Signal/slot system. This article mainly introduces the compilation and installation of SIP and the birth of C + + code into Python under the window pla

In a conversation, there are other correlations that will be sent. A conversation is an end-to-end sip relationship between two users that lasts a certain amount of time. The dialog process requires that the information between the two user agents be ordered and that the request be routed properly. In this specification, only invite requests can be used to establish a session. When a UAC makes a request in a conversation, it follows not only the gener
