Aviation Command Communication System Analog Telephone (Softphone) Function

Core Function Implementation

Integrate complete pure software telephone functionality within the PC client and WEB interface, without relying on physical IP phone hardware, supporting all operations including call dialing, answering, hold, transfer, hang-up, caller ID, and call history query; after a user account logs into the softphone, the extension number and call functions move with the account to any authorized workstation, ensuring communication continuity in emergency scenarios.

Technical Implementation Solution

Softphone Core Engine: Develop a pure software telephone client based on SIP.js + WebRTC, seamlessly integrated with the backend domestic IP-PBX, compatible with mainstream voice protocols such as SIP and H.323, supporting HD Voice high-definition voice calls;

Account Roaming and Follow-me: User extension numbers, personal call settings, call history, and permission configurations are all bound to the user account. After logging into the system at any authorized workstation, the softphone automatically completes SIP registration and call functions become immediately available, achieving "account follow-me, uninterrupted communication";
