Abstract: Aiming at the problems of complex and diversified communication networks in various emergency rescue scenarios and the independence of the command and communication systems of ordinary dispatch consoles, a SIP-based emergency communication console is proposed, which not only describes in detail the composition of the hardware modules of the console, but also elaborates on the application of SIP soft switching technology in the program. The console supports access to digital and analog communication networks to realize voice communication and multimedia video communication through wired and wireless broad band communication. Based on SIP soft switch technology, the concept of fully converged communication is proposed for the emergency communication needs under different emergency rescue scenarios to complete the unified command and dispatching, which provides a reference for the development direction of the emergency communication console.
