RADVISION's SIP server platform is a framework for building all SIP servers and supporting fast and effective application software development for SIP servers, as RADVISION's SIP toolkit is in the leading position in the market, therefore, the platform implements the functions of the

I believe everyone is in touch with the SIP protocol. In the previous article, we also discussed the content of the SIP protocol. If you are not clear about it, you can review it a little. We know that the SIP protocol has a huge development potential in the network communication field. Here we will explain the content of the IMS and

I have developed custom Sip/IMS video clients, and supported voice, video, and instant communication functions. The video formats support h263, h264, and MPEG4 soft decoding, and provide hardware coding/decoding interfaces, provide servers. If you are interested, please contact me.

The HTML5 SIP client is an open-source client that fully utilizes JavaScript to integrate social networking (Facebook, Twitter, Google +), online games, and e-commerce applications. No extensions, no plug-ins, or necessary gateways. The video stack technology relies on WebRTC. Like Demo Video demo on the home page, you can easily implement real-time video/audio calls between Chrome and IOS/Android mobile devices. This client is a technology that can

the Application Scenario (Call Center) of the author, the main problem to be solved is that the agent can traverse in the NAT environment and send information to the server. Because the SIP Soft Phone used by the agent is developed by our company, it can be ensured that rport and received are supported. 3.2 instance The following is an instance that sends the register information. The request's via header contains the rport parameter with no value,

In the process of this test, the most disturbing problem is that the gateway is not receiving the alerting event during the call, causing the state machine to be disturbed. In fact, the SIP protocol already defines the reliability of the temporary response. It is stipulated in the SIP standard that the definition of the reliable transmission of temporary messages during the call establishment process can be

We have already learned about the SIP protocol, which we will always see in the Unified Communication Platform and VOIP business. So here we will give you a brief discussion on the development of the SIP protocol and the SIP protocol stack. 1. About the SIP protocol Currently, there are three basic communication protoc

During our understanding of the SIP protocol stack, we found that the application of the SIP Protocol can be implemented on many platforms and devices. The following software is required for the establishment of the SIP Soft Phone development environment to develop a SIP-based soft phone on windows or linux platforms:

Project name Description Files Activity % SIPP SIPP is a performance testing tool for the SIP protocol. its main features are basic sipstone scenarios, TCP/UDP Transport, customizable (XML based) scenarios, dynamic adjustement of call-rate and a comprehensive set of real-time statistics. 84.69% Shtoom-a python sip framework phone A software

The pioneers in the converged communication field are currently sending the Session Initiation Protocol (SIP ). SIP has become the main protocol for VoIP and other real-time media communications on the packet network. There are several reasons for the popularity and success of SIP. First, SIP is regarded as a protocol

Today, wireless service providers have been seeking cheaper voice services to maintain their market share. Obviously, the secret to surpassing competitors is to launch some attractive services with additional charges. However, existing technologies such as SMS need the same cost model as voice. Therefore, wireless service providers focus on the commercial technology of Session Initiation Protocol (SIP. SIP

client should try again in the sip uri mode. If you receive a 420 (incorrect extension) Response (rfc3261 section 21.4.15 ), the request lists an extension option not supported by the proxy or uas in the require or proxy-require header domain. UAC should ignore the extensions listed in the response's unsupported header and try again. In all the above cases, the request is modified accordingly and a new request is created. This new request creates a n

According to the RFC3261-13.2.1, the offer/answer model used by the SIP is established in the dialog environment. The RFC also specifically imposes restrictions on offer/answer Interaction: 1.The initial offer must be in the invite message or the first reliable non-Failed response. Note: At that time, the reliability Effect of rfc3261 was only 2 **. Next we will talk about 1 ** (except 100. 2.If the initial offer is in the invite message, the answer m
