Solution Overview

Problem

Conventional contact centers and automated call servicing systems face inefficiencies in testing and servicing, leading to processing bottlenecks, erroneous information, and mismanaged calls due to the lack of effective testing and servicing techniques, resulting in suboptimal customer experiences.

Innovation Solution

A modular system that connects users with SIP providers to execute servicing tasks through a central hosting server, enabling individual access to resources for efficient and accurate testing and servicing of telephony systems, reducing human and processing requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional testing and servicing techniques are used, then system complexity is reduced, but productivity and accessibility are severely limited due to processing bottlenecks and minimal user access

Engineering Contradiction:
Improvetesting and servicing efficiencyVSAvoidsystem architecture complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments testing and servicing functions into modular components distributed across multiple user devices and servers. Each user device can independently execute testing tasks against the telephony system, eliminating the need for a centralized complex testing infrastructure and allowing parallel access by multiple users simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system enables user devices to perform multiple functions including initiating test calls, receiving test results, and executing servicing tasks through a unified interface. The same communication infrastructure used for normal telephony operations is also utilized for testing and servicing, eliminating dedicated complex testing equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of time

If conventional centralized testing methods are used, then device complexity is minimized, but loss of time occurs due to processing bottlenecks and wait times for multiple users

Engineering Contradiction:
Improvewait time for testing and servicingVSAvoidaccessibility to testing resources
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system transitions from a single centralized testing queue to a distributed multi-dimensional architecture where multiple users can access testing resources simultaneously across different devices and locations. This eliminates the sequential processing bottleneck by adding spatial and temporal dimensions to resource access.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Users can independently initiate and execute their own testing and servicing tasks without requiring manual intervention from system administrators or shared technical support staff. The system provides self-service capabilities through automated task execution and result delivery directly to user devices.

Inventive Principle:
Principle #25Self-service

3Reliability

If conventional testing techniques are used, then system resources are conserved, but reliability deteriorates due to erratic performance and uncaptured call data

Engineering Contradiction:
Improvetesting accuracy and data captureVSAvoidprocessing resources and memory
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system creates virtual copies of telephony system components and test environments that can be accessed and tested without affecting the production system. Test calls and servicing tasks are executed in isolated virtual instances, ensuring accurate data capture and reliable testing results without consuming excessive physical resources.

Inventive Principle:
Principle #26Copying

AI summary

Modular technologies for servicing telephony systems are disclosed herein. An example method includes receiving a user request to service a telephony system of a user, and transmitting a set of available session initiation protocol (SIP) providers to a user computing device for analysis by the user. Responsive to receiving a user input, the example method includes connecting the user computing device to an SIP trunk, connecting to a serviceable call location included in the user request through the SIP trunk, wherein connecting to the serviceable call location initiates a data stream, and executing a servicing task included in the user request. The example method includes recording a portion of the data stream during execution of the servicing task, storing the portion of the data stream, and causing the user computing device to display the portion of the data stream for viewing by the user.
