The study and implementation of VoIP intelligent voice communication system based on SIP protocol

VoIP can make a real-time voice communication by using IP network. SIP protocol is an application-layer session control protocol which can implement VoIP system. Based on the research of VoIP related technology and SIP protocol, this paper proposes a design scheme of VoIP intelligent voice communication system which is based on C/S architecture and accords with the SIP protocol specifications. The design scheme is also implemented on the corresponding development platform. Besides, this paper also test and verify the conversation process of communication terminal and its functions. The system has the advantages of small investment, low cost, convenience and practicality, high reliability, good security, etc. It is of great application and popularization value.
