Telecommunications Terminal Call Redirection for PBX Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications systems with private branch exchanges (PBXs) face challenges in efficiently redirecting calls between multiple PBX sites, leading to delays and increased toll charges, especially when users attempt to access features like call forwarding or voice mail from outside their home PBX area.
Innovation Solution
Implementing additional software on affiliated terminals to monitor user input and automatically redirect calls to a different PBX before the user completes dialing, ensuring seamless interaction with the new PBX using stored user profiles and authentication processes, thus reducing user awareness of the redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system waits for the user to complete dialing before redirecting the call, then the user can provide complete calling information, but call setup delays increase and productivity decreases
Solution Approach 1:
The system performs preliminary action by analyzing user input in real-time during the dialing process and making redirection decisions before the user completes dialing. The terminal monitors each digit entered and determines call redirection eligibility at intermediate stages, rather than waiting for complete dialing to finish.
Solution Approach 2:
The system implements feedback by continuously monitoring user input during dialing and adjusting the call setup process based on real-time analysis. The terminal provides feedback by determining whether redirection should be initiated based on the digits entered so far, creating an iterative decision-making process that balances accuracy and speed.
2Productivity
If the system redirects calls automatically before dialing completes, then call setup delays are reduced and productivity increases, but the complexity of the terminal software increases
Solution Approach 1:
The terminal software achieves multi-functionality by integrating multiple capabilities into a single system: it monitors user input, determines redirection eligibility, initiates redirection processes, and manages call setup. This universal approach consolidates what would otherwise be separate functions into one cohesive software system.
Solution Approach 2:
The terminal performs self-service by autonomously monitoring its own input, determining redirection decisions, and executing the redirection process without requiring external intervention. The system serves itself by making intelligent decisions about call routing based on real-time analysis of user input.
3Loss of energy
If the system redirects calls to different PBXs, then toll charges are optimized and cost decreases, but the user may become aware of the redirection and experience user experience degradation
Solution Approach 1:
The terminal acts as an intermediary between the user and the PBX redirection process. It mediates the interaction by transparently handling the redirection logic, presenting a consistent interface to the user while managing the complex redirection process in the background without user awareness.
Solution Approach 2:
The system applies local quality by maintaining different behaviors for different parts of the system: the user interface remains consistent and unchanged, while the underlying call routing logic adapts to optimize costs. The local quality of the user experience is preserved even as the global optimization of toll charges is achieved through redirection.

AI summary
An apparatus and methods are disclosed for use by organizations that have PBXs at a plurality of sites. The invention pertains to cell phone calls from an affiliated terminal to her “home” private branch exchange. For example, an employee who works at the Chicago branch office might call the Chicago office's PBX to invoke a feature such as setting up call forwarding, retrieving voice mail, etc. Such calls might be automatically and transparently directed to another PBX when it is advantageous to do so. In the illustrative embodiment, the need or desirability to redirect such calls to another PBX is ascertained while the caller is still in the process of entering all of the required calling information. The effect of assessing whether to redirect the call in parallel with the caller entering the information is to reduce the delays otherwise experienced by the caller when placing calls outside of the enterprise area served by the home private branch exchange.
