This invention relates to the field of voice communication technology and discloses an intelligent call allocation system and method for voice gateways. The intelligent call allocation method for voice gateways includes: encapsulating performance data and node health into load fingerprints; generating capacity tokens and establishing a token pool in the voice gateway; using a utilization prediction model to predict utilization and a scheduling scoring model to calculate a comprehensive scheduling score; constructing a ready set based on candidate nodes; selecting the first node from the ready set for call allocation and monitoring call status; and activating a backpressure mechanism when the inbound call rate exceeds a preset multiple of the capacity token acquisition rate. This invention achieves precise capacity control and load allocation through load fingerprint generation and capacity token pooling management; improves prediction accuracy by predicting future node utilization through a utilization prediction model; and calculates a comprehensive scheduling score using an ensemble learning algorithm based on decision trees, providing an efficient, intelligent, and reliable call allocation method for enterprise voice networks.

This invention belongs to the field of communication noise detection and processing technology, and relates to a method and system for testing low-noise power supplies using waveforms. The method connects the power supply under test (DUT) and a voice gateway, and powers them on in real time. The voice gateway is connected to an external noise-shielded environment via its voice interface. Within this environment, the voice gateway is modulated to a periodic state of comfortable noise or a dial tone, and the sound is played. The playing sound is acquired and processed, and based on the processed sound and the sound signal waveform, the noise level of the DUT is detected in real time. This transforms uncontrollable human-induced noise into an electrical signal measurable by an oscilloscope, accurately determining whether the power supply meets requirements. In other words, by utilizing a clean environment, the unmeasurable power frequency noise on the telephone line is converted into a differential-mode signal measurable by an oscilloscope through a physical sound isolation process, providing testers with an objective experimental result.

This invention relates to the field of Internet communication technology, specifically to a cross-channel adaptive circuit breaker routing method for SMS based on time decay scoring. The method includes receiving service requests, real-time sliding collection of success rates, latency, and error codes for each channel, and introducing a time decay factor for index aggregation. Based on multi-dimensional operational indicators of the channels, index decay trends, and different service types, a dynamic channel comprehensive score is calculated and generated. Three-state management is implemented for each channel according to the dynamic comprehensive score. Based on the three-state management results, requests are routed to appropriate SMS channels. The overall message flow latency is monitored, and SMS flow is blocked in a timely manner, downgrading to a voice gateway for TTS calls. This invention achieves synchronous adaptation of the sample window and decay coefficient based on channel stability, ensuring accurate Rdecay calculation and avoiding scoring lag or distortion caused by traditional static parameter configuration, thus improving the accuracy of routing decisions.
