AI Technical Summary

Technical Problem

The hardware information of existing VoIP phones is implemented through system properties and default phone configuration files. This means that each version update requires modification of system code and configuration files, which is laborious to maintain and easily modified by users, failing to meet the ever-increasing model and functional requirements.

Method used

The configuration information is obtained through the user terminal, and encrypted configuration files and plaintext configuration files are compiled and generated. An encrypted script file is generated using the AESECB encryption method, and the executable file is decrypted and set as a system property when the VoIP phone starts up, thus distinguishing the hardware information and software logic differences of different products.

Benefits of technology

It enables differentiation of functionalities among different products without modifying the upper-layer software, thereby increasing product diversity, reducing maintenance time and costs, and enhancing security.
