THE RESEARCH AND IMPLEMENTATION OF GENERAL SIP CALL CONTRAL MODEL

To simplify the development of SIP call control service, a general SIP call control model called SIPCC was put forward in this paper. The key issues about SIPCC, such as model and the underlying SIP protocol mapping, implement scheme about SIPCC resource adapter were specified. An example implementing a service based on SIPCC was introduced to illustrate how SIPCC can simplify the development of service.
