Details：
Based on the NGN architecture and using the international standard SIP protocol, it has excellent compatibility and functional scalability. The system expands commonly used audio and video services, achieving for the first time the integration of multiple functions such as voice exchange, group call amplification, broadcasting, recording, video linkage, alarm, contingency plan, electronic map, etc. on the same platform. By integrating voice and video, efficient emergency response can be achieved. The system can adopt a fiber optic transmission architecture, support network cascade mode, and has various advantages such as stable transmission performance, long transmission distance, strong resistance to electromagnetic interference, and convenient networking.
