SIP response code The response code is included, and the HTTP/1.1 response code is extended. Not all HTTP/1.1 Response codes are properly applied, but only pointed out in the discount. Other HTTP/1.1 Response codes should not be used. In addition, SIP also defines a new response code series, 6xx. 1. Temporary response 1xxA temporary response, that is, a message response, indicates that the other server is

The integration of unified communication involves software, hardware, mobile devices, and fixed devices. The standards and protocols are different. Therefore, the integration is difficult. In terms of IP phones and desktop applications, there are mainly SIP and H.323 Protocols; mobile videos are H.324M; Monitoring also includes H.323, SIP and proprietary protocols as well as MEPG2, MEPG4, and H. 264 and ot

In my previous article, I introduced how to use a SIP Soft Phone for direct calls. However, if many other users need to talk to each other, at the same time, authentication and control of User Account logon is required based on security considerations, in these cases, you need to establish a sipserver.Role of sipserver:Call control and processing functions, business provision/support functions, user management functions, protocol processing functions,

Haha. I 've talked about some SIP application scenarios. I will write some theoretical and boring things in the future. Before that, let's continue to make it easy to tell you a story about how to learn HTTP. At the very beginning, I took an HTTP book first. In short, it was a brick book. After reading the two chapters, we found that we should use the knowledge of TCP/IP. So let's look at TCP network programming. Two months later, I still don't kno

After OS X upgrades to El Capitan, it provides a security-related pattern called SIP (System Integrity Protection), also known as rootless mode, which is a new feature that emphasizes security for OS X, which prohibits the software from being used as root in Mac running on, upgrade to OS X 10.11 Maybe you'll see some apps are disabled so that/usr/bin folders we can't read and write properly, but it also causes some programs (such as homebrew and Git)

The concept of unified communication needs to be understood from the combination of multiple protocols. Among them, there is more participation in the SIP protocol. The integration of unified communication involves software, hardware, mobile devices, and fixed devices. The standards and protocols are different. Therefore, the integration is difficult. For IP phones and desktop applications, the main protocol is S
