PBX Group Call Logging via Segmented Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional private branch exchanges cannot determine whether incoming calls were routed to a specific extension phone or an extension group, leading to difficulties in maintaining an accurate log of calls for operators in group settings.
Innovation Solution
A private branch exchange system that includes a caller information detector, a group incoming call table correlating extension numbers with group numbers, and a controller to transmit incoming call signals to relevant extension phones and store caller information in a group log, allowing for identification and logging of calls addressed to an extension group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If incoming calls are separately registered in logs maintained for individual extension phones, then each extension phone can display its own call log, but it cannot be determined whether an incoming call was routed to a group or to a specific extension phone
Solution Approach 1:
The patent segments the logging function by creating separate log storage areas: individual extension phone logs and group logs. The controller identifies whether an incoming call is routed to a specific extension phone or to a group, and stores the call information in the appropriate log. This segmentation preserves call routing information while maintaining manageable log structures.
Solution Approach 2:
The controller acts as an intermediary between the call routing system and the log storage system. It receives call routing information, determines the destination (individual extension or group), and directs the logging accordingly. This intermediary function ensures accurate tracking of call routing without requiring complex modifications to the existing log infrastructure.
2Productivity
If operators in a group must check individual phone logs to determine if a call was answered, then call information is tracked, but operators waste time manually examining multiple logs
Solution Approach 1:
The patent merges the logging function for group calls into a centralized group log that is accessible to all operators in the group. When a call is routed to a group, the controller stores the call information in the group log, which all operators can view on their respective phones. This eliminates the need for operators to manually check individual phone logs, significantly reducing time loss while maintaining full call tracking capability.
3Ease of operation
If a centralized group log is implemented, then operators can easily access call information, but the system complexity increases
Solution Approach 1:
The controller performs preliminary action by automatically identifying whether an incoming call is routed to a specific extension phone or to a group, and pre-sorting the call information into the appropriate log before operators need to access it. This preliminary classification simplifies the operator's task of accessing call information while the controller handles the complexity of routing determination and log selection in the background.

AI summary
It is one objective of the present invention to provide a private branch exchange that can identify calls to be routed to an extension phone group.A private branch exchange according to this invention comprises: a caller information detector for, when a call is received, obtaining caller information; a group incoming call table in which two or more extension numbers are correlated with an extension incoming call group number; and an incoming call group controller for, when a call received through the telephone line is for an extension incoming call group number, extracting from the group incoming call table extension numbers that are correlated with the extension incoming call group number and transmitting an incoming call signal to extension phones corresponding to the extension numbers, and also for storing, in a group incoming call log table, a caller number that is obtained by the caller information detector.
