%X Through the analysis and research on the SIP protocol, this paper proposes a solution based on SIP softswitch. It can be used to implement the networking exchange between the base stations in the trunking system, to develop corresponding SIP agent and SIP proxy server, and to solve the NAT penetration problems. The system has been tested in the public security special network.
