VOIP (Voice over IP) is a each other Voice or video on the IP network technology, is that people can enjoy cheaper rates, and even completely free, and all kinds of multimedia value-added services, service content and the method of telecom operators has changed dramatically. At the same time, in order to decrease the cost of calls to meet the needs of more users, more and more companies are using IP phone system. These companies usually have Ethernet network has been set up, using VoIP can unify different platform network and greatly reduce the telephone costs. VoIP technology is increasingly becoming one of the mainstream of the communication technology. In this paper, based on the SIP protocol of VoIP system scheme, key support SIP terminal softswitch solution was studied. On the basis of the origin
