We also talked about the SIP Protocol and related SIP protocol stack. In this paper, we propose a software structure and design implementation scheme of the software telephone based on the SIP protocol. this solution is based on the embedded Windows CE platform. The middleware uses the Open-Source SIP protocol stack oSIP/eXosip, through protocol stack transplantation and application development on the protocol stack, the SIP software phone is implemented. the test results show that the software

Single radio voice call continuity (srvcc) srvcc is an LTE functionality that allows a VoIP/IMS call in the LTE packet domain to be moved to a legacy voice domain (GSM/UMTS or CDMA 1X ). consider a case where a new LTE network operator wants to move voice services to VOIP over IMS in conjunction with the deployment of an LTE access network. in the

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, proxy/targeted servers, location servers, and PSTN gateways. Currently, the latest standard of the SIP protocol is RFC3261. Major network equipment providers can cu
in the Data step, PDV sets all variables as missing values, which are represented by "." in SAS. Then, assign values to the variables when executing other statements. However, if we use the retain statement in the Data step
PDV will not clear the variable corresponding to the retain statement, but will keep it until the next change is executed, so that it can complete the accumulation of the initial value not 0 as mentioned above.
