VoIP Teleagent Voice Quality Management via RTP Snooping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing voice quality over VoIP networks for teleagents is challenging due to varying broadband connections, unreliable Internet Service Providers, and environmental factors within teleagents' homes, making it difficult to ensure toll-quality voice service across a large geographic area.
Innovation Solution
A voice quality management system that includes tools and modules to monitor and detect faults in the communication network, identify performance parameters affecting voice quality, and proactively address issues by removing teleagents with poor voice quality from the active pool until problems are resolved, using RTP snooping and synthetic traffic to verify corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If teleagents use low-cost unmanaged broadband services, then cost is reduced, but voice quality becomes unreliable
Solution Approach 1:
The system performs preliminary monitoring and detection of voice quality parameters before calls are assigned to teleagents. The proactive voice quality management system continuously monitors network conditions, jitter, and other performance metrics in advance, allowing the enterprise to identify and remove teleagents with poor voice quality connections before they are assigned customer calls, thus ensuring reliable voice quality while allowing teleagents to use cost-effective broadband services.
2Adaptability or versatility
If teleagents are deployed over large geographic areas, then telecommuting flexibility is improved, but network quality becomes difficult to manage
Solution Approach 1:
The system implements continuous feedback loops where voice quality parameters are monitored in real-time, compared against predefined thresholds, and automatically trigger actions such as removing teleagents from the active pool when quality degrades. This automated feedback mechanism simplifies network management across geographically distributed teleagents by eliminating the need for manual monitoring and intervention, thus maintaining adaptability while reducing management complexity.
3Reliability
If voice quality is monitored in real-time, then voice quality consistency is improved, but system complexity increases
Solution Approach 1:
The voice quality monitoring system is designed to be self-managing, automatically detecting voice quality parameters, comparing them against thresholds, and executing corrective actions without human intervention. The system monitors itself and the network conditions, automatically removing teleagents with poor voice quality from the active pool and restoring them when conditions improve, thus ensuring voice quality consistency while minimizing the complexity of manual monitoring and control.
4Reliability
If teleagents are removed from active pool when voice quality degrades, then voice quality reliability is improved, but call handling productivity decreases
Solution Approach 1:
The system maintains a reserve pool of pre-vetted teleagents with confirmed adequate voice quality connections. When active teleagents are removed due to voice quality degradation, the system can quickly assign calls from the reserve pool without significant disruption to call handling capacity. This beforehand preparation cushions the impact on productivity while maintaining voice quality reliability, as the reserve pool is pre-screened and ready to immediately承接 calls.
Data Source
AI summary
A system for transferring a call from one teleagent to another in response to a loss of voice quality in a voice over Internet protocol (VoIP) communication system. Network parameters that affect voice quality over broadband connections are detected manually or automatically and an alert is generated. In response to the alert, a supervisor can transfer the call in progress to a second agent so that a better communication link can be provided and voice quality restored. Such transfer can be seamless to the caller. In different embodiments, transfer, or intercept, can occur manually or automatically (e.g., without supervisor intervention).
