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

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

1 , what is SIPSIP (Session Initiation Protocol) belongs to the IP Application layer protocol, which is used to provide the user with session application on the IP network. A session refers to the communication of voice, video, and other media forms

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

Basic SIP Application As one of the main VOIP communication protocols, the SIP protocol is simple, flexible, and open, and is gradually dominant in the VOIP communication field. The main methods used for SIP Communication include SIP terminals,

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

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

In the dialog, other related information will be sent. A conversation is an end-to-end sip relationship between two users that lasts for a certain period of time. The dialog process requires that the information between the two user proxies is

For multi-user communications, there are also common protocols for standardized management, such as the previously mentioned SDP and SIP (Session initiation Protocol), which is a control protocol belonging to the application layer, primarily used to

1.1 SIP Message Classification SIP protocol is formed in the form of layer protocol, that is, its behavior is described in a set of relatively independent processing stages, the relationship between each phase is not very close. The SIP protocol

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the

The SIP protocol is an application-layer control protocol used to establish, modify, and terminate multimedia sessions. It draws a lot from mature HTTP protocols (such as text format encoding and method in request messages ), the text-based UTF-8
