Bidirectional Emulator for Legacy PBX to SIP Protocol Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy PBX and key systems face challenges in integrating with multi-vendor communication systems and devices, leading to loss of features and functionality when transitioning to SIP-based VoIP technology, resulting in high capital expenditure for enterprises.
Innovation Solution
A system and process that uses an emulator module with a line signal dictionary to translate communication protocols between legacy telephone devices and SIP communication servers, enabling bidirectional emulation and preserving feature functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy PBX and key systems are integrated with SIP communication servers, then compatibility and support for multi-vendor systems is improved, but loss of features and functionality occurs
Solution Approach 1:
The patent introduces an emulator module as an intermediary component between legacy PBX/key systems and SIP communication servers. This emulator module contains a line signal dictionary that stores waveform characterizations and translates signals bidirectionally, enabling legacy devices to communicate with SIP systems while preserving their original features and functionality without requiring direct integration that would cause feature loss.
2Adaptability or versatility
If legacy PBX and key systems are replaced with SIP-based systems, then modern communication technology adoption is improved, but capital expenditure increases
Solution Approach 1:
The patent creates a virtual copy of the legacy PBX and key system functionality through the emulator module. Instead of physically replacing legacy devices with expensive SIP-based hardware, the system copies the functionality of legacy systems into software-based emulators that run on existing SIP infrastructure, dramatically reducing capital expenditure while enabling modern technology adoption.
3Stability of the object's composition
If proprietary hardware and software are used for core communication platforms, then device deployment homogeneity is improved, but integration of multi-vendor systems is limited
Solution Approach 1:
The patent implements a universal emulator module that can handle multiple vendor-specific line signal protocols through a single platform. The line signal dictionary stores waveform characterizations for different device types, allowing the emulator to translate signals from various proprietary systems into a common SIP-based format, thereby enabling multi-vendor integration while maintaining deployment simplicity.

AI summary
The present systems and processes are directed to bridging telephone communications, such that a SIP communication server is able to communicate with the legacy PBX or key system interface for interworking connectivity of the devices. A bidirectional emulator module is provided permitting a communication session with legacy analog device and/or digital device. In certain embodiments, analog and digital telephones are registered with the emulator. An external telephone system such as a SIP communication server is also registered. A line dictionary contains the communication protocols of the analog and digital telephones and external telephone system. Outgoing line traffic and incoming line traffic are monitored in real-time, where the emulator module translates the user requests and line traffic according to the respective communication protocol data retrieved from the line dictionary.
