Understand the SIP session initialization Protocol; find out the real-time Transport Protocol, RTP and UDP protocol; Learn some audio and video coding standard; and finally the implemented application demo video call between two mobile phone platform android programming language. Next is the progress going into learn real-time Transport Protocol, RTP, is a protocol provides transport functions suitable for applications that transmit data to bring real-time features such as phone and interactive tv. Along with that was conducted to learn about the UDP protocol, the Protocol is message-oriented transport layer's smallest. Both RTP and UDP protocol that constitute a part of functions of the transport layer protocol. With an audience of sound and image, parallel understanding theory is carried encrypted/decrypted by preeminent compression standard and is popular nowadays is that the compression standard h.263, h.264 and g.711u, g. 711A aims to optimize bandwidth, improving transfer speeds.The last is going to deploy and execute the application. Conduct analysis, simulation and applications, along with using 3CX Phone System software, acts as a SIP Server to make the call.
